Spontaneously arising channels transporting the phytohormone auxin, created by coordinated polar localizations of PIN-FORMED 1 (PIN1) auxin exporter, provide positional cues for these as well as other plant patterning processes. To find regulators acting downstream of auxin and the TIR1/AFB auxin signaling pathway essential for PIN1 coordinated polarization during auxin canalization, we performed microarray experiments. Besides the known components of general PIN polarity maintenance, such as PID and PIP5K kinases, we identified and characterized a new regulator of auxin canalization, the transcription factor WRKY DNA-BINDING PROTEIN 23 (WRKY23).\r\nNext, we designed a subsequent microarray experiment to further uncover other molecular players, downstream of auxin-TIR1/AFB-WRKY23 involved in the regulation of auxin-mediated PIN repolarization. We identified a novel and crucial part of the molecular machinery underlying auxin canalization. The auxin-regulated malectin-type receptor-like kinase CAMEL and the associated leucine-rich repeat receptor-like kinase CANAR target and directly phosphorylate PIN auxin transporters. camel and canar mutants are impaired in PIN1 subcellular trafficking and auxin-mediated repolarization leading to defects in auxin transport, ultimately to leaf venation and vasculature regeneration defects. Our results describe the CAMEL-CANAR receptor complex, which is required for auxin feed-back on its own transport and thus for coordinated tissue polarization during auxin canalization." alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Jakub full_name: Hajny, Jakub id: 4800CC20-F248-11E8-B48F-1D18A9856A87 last_name: Hajny orcid: 0000-0003-2140-7195 citation: ama: Hajny J.

Nonetheless, the evolutionary origin of their unprecedented morphological complexity remains largely an enigma. Here, we show that the coevolution of cis-regulatory and coding regions of PIN-FORMED (PIN) auxin transporters confined their expression to certain cell types and directed their subcellular localization to particular cell sides, which together enabled dynamic auxin gradients across tissues critical to the complex architecture of flowering plants. Extensive intraspecies and interspecies genetic complementation experiments with PINs from green alga up to flowering plant lineages showed that PIN genes underwent three subsequent, critical evolutionary innovations and thus acquired a triple function to regulate the development of three essential components of the flowering plant Arabidopsis: shoot/root, inflorescence, and floral organ. Our work highlights the critical role of functional innovations within the PIN gene family as essential prerequisites for the origin of flowering plants.' acknowledgement: 'We thank C.Löhne (Botanic Gardens, University of Bonn) for providing us with A. trichopoda.

MYB transcription factors play a crucial role in plants’ biological processes, but the function of pineapple MYB genes is still obscure. In this study, one of the pineapple MYB transcription factors, AcoMYB4, was isolated and characterized. The results showed that AcoMYB4 is localized in the cell nucleus, and its expression is induced by low temperature, drought, salt stress, and hormonal stimulation, especially by abscisic acid (ABA). Overexpression of AcoMYB4 in rice and Arabidopsis enhanced plant sensitivity to osmotic stress; it led to an increase in the number stomata on leaf surfaces and lower germination rate under salt and drought stress. Furthermore, in AcoMYB4 OE lines, the membrane oxidation index, free proline, and soluble sugar contents were decreased. In contrast, electrolyte leakage and malondialdehyde (MDA) content increased significantly due to membrane injury, indicating higher sensitivity to drought and salinity stresses. Besides the above, both the expression level and activities of several antioxidant enzymes were decreased, indicating lower antioxidant activity in AcoMYB4 transgenic plants. Moreover, under osmotic stress, overexpression of AcoMYB4 inhibited ABA biosynthesis through a decrease in the transcription of genes responsible for ABA synthesis (ABA1 and ABA2) and ABA signal transduction factor ABI5. These results suggest that AcoMYB4 negatively regulates osmotic stress by attenuating cellular ABA biosynthesis and signal transduction pathways.

MCS connections enable the nonvesicular exchange of information between organelles and allow them to coordinate responses to changing cellular environments. In plants, the importance of MCS components in the responses to environmental stress has been widely established, but the molecular mechanisms regulating interorganelle connectivity during stress still remain opaque. In this report, we use the model plant Arabidopsis thaliana to show that ionic stress increases endoplasmic reticulum (ER)–plasma membrane (PM) connectivity by promoting the cortical expansion of synaptotagmin 1 (SYT1)-enriched ER–PM contact sites (S-EPCSs). We define differential roles for the cortical cytoskeleton in the regulation of S-EPCS dynamics and ER–PM connectivity, and we identify the accumulation of phosphatidylinositol 4,5-bisphosphate [PI(4,5)P2] at the PM as a molecular signal associated with the ER–PM connectivity changes. Our study highlights the functional conservation of EPCS components and PM phosphoinositides as modulators of ER–PM connectivity in eukaryotes, and uncovers unique aspects of the spatiotemporal regulation of ER–PM connectivity in plants. article_processing_charge: No article_type: original author: - first_name: Eunkyoung full_name: Lee, Eunkyoung last_name: Lee - first_name: Steffen full_name: Vanneste, Steffen last_name: Vanneste - first_name: Jessica full_name: Pérez-Sancho, Jessica last_name: Pérez-Sancho - first_name: Francisco full_name: Benitez-Fuente, Francisco last_name: Benitez-Fuente - first_name: Matthew full_name: Strelau, Matthew last_name: Strelau - first_name: Alberto P. full_name: Macho, Alberto P. last_name: Macho - first_name: Miguel A. full_name: Botella, Miguel A. last_name: Botella - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Abel full_name: Rosado, Abel last_name: Rosado citation: ama: Lee E, Vanneste S, Pérez-Sancho J, et al.

In plants, it is unknown how cell polarities are connected to organismal axes and translated to division. Here, we identify Arabidopsis SOSEKI proteins that integrate apical–basal and radial organismal axes to localize to polar cell edges. Localization does not depend on tissue context, requires cell wall integrity and is defined by a transferrable, protein-specific motif. A Domain of Unknown Function in SOSEKI proteins resembles the DIX oligomerization domain in the animal Dishevelled polarity regulator. The DIX-like domain self-interacts and is required for edge localization and for influencing division orientation, together with a second domain that defines the polar membrane domain. Our work shows that SOSEKI proteins locally interpret global polarity cues and can influence cell division orientation. Furthermore, this work reveals that, despite fundamental differences, cell polarity mechanisms in plants and animals converge on a similar protein domain. article_processing_charge: No author: - first_name: Saiko full_name: Yoshida, Saiko id: 2E46069C-F248-11E8-B48F-1D18A9856A87 last_name: Yoshida - first_name: Alja full_name: Van Der Schuren, Alja last_name: Van Der Schuren - first_name: Maritza full_name: Van Dop, Maritza last_name: Van Dop - first_name: Luc full_name: Van Galen, Luc last_name: Van Galen - first_name: Shunsuke full_name: Saiga, Shunsuke last_name: Saiga - first_name: Milad full_name: Adibi, Milad last_name: Adibi - first_name: Barbara full_name: Möller, Barbara last_name: Möller - first_name: Colette A. full_name: Ten Hove, Colette A. last_name: Ten Hove - first_name: Peter full_name: Marhavy, Peter id: 3F45B078-F248-11E8-B48F-1D18A9856A87 last_name: Marhavy orcid: 0000-0001-5227-5741 - first_name: Richard full_name: Smith, Richard last_name: Smith - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Dolf full_name: Weijers, Dolf last_name: Weijers citation: ama: Yoshida S, Van Der Schuren A, Van Dop M, et al.

On a molecular level, stress conditions result in elevation of reactive oxygen species (ROS) production causing oxidative stress associated with oxidation of proteins and nucleic acids as well as impairment of membrane functions. Adaptation of root growth to ROS accumulation is facilitated through modification of auxin and cytokinin hormone homeostasis. Here, we report that in Arabidopsis root meristem, ROS-induced changes of auxin levels correspond to decreased abundance of PIN auxin efflux carriers at the plasma membrane (PM). Specifically, increase in H2O2 levels affects PIN2 endocytic recycling. We show that the PIN2 intracellular trafficking during adaptation to oxidative stress requires the function of the ADP-ribosylation factor (ARF)-guanine-nucleotide exchange factor (GEF) BEN1, an actin-associated regulator of the trafficking from the PM to early endosomes and, presumably, indirectly, trafficking to the vacuoles. We propose that H2O2 levels affect the actin dynamics thus modulating ARF-GEF-dependent trafficking of PIN2. This mechanism provides a way how root growth acclimates to stress and adapts to a changing environment. article_processing_charge: No author: - first_name: Marta full_name: Zwiewka, Marta last_name: Zwiewka - first_name: Agnieszka full_name: Bielach, Agnieszka last_name: Bielach - first_name: Prashanth full_name: Tamizhselvan, Prashanth last_name: Tamizhselvan - first_name: Sharmila full_name: Madhavan, Sharmila last_name: Madhavan - first_name: Eman Elrefaay full_name: Ryad, Eman Elrefaay last_name: Ryad - first_name: Shutang full_name: Tan, Shutang id: 2DE75584-F248-11E8-B48F-1D18A9856A87 last_name: Tan orcid: 0000-0002-0471-8285 - first_name: Mónika full_name: Hrtyan, Mónika id: 45A71A74-F248-11E8-B48F-1D18A9856A87 last_name: Hrtyan - first_name: Petre full_name: Dobrev, Petre last_name: Dobrev - first_name: Radomira full_name: Vanková, Radomira last_name: Vanková - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Vanesa B. full_name: Tognetti, Vanesa B. last_name: Tognetti citation: ama: Zwiewka M, Bielach A, Tamizhselvan P, et al.

In addition, axr3 mutants showed reduced auxin‐mediated starch granule accumulation and disruption of gravitropism within the root apex.\r\n\r\nOur results indicate that auxin‐mediated statolith production relies on the TIR1/AFB‐AXR3‐mediated auxin signaling pathway. In summary, we propose a dual role for auxin in gravitropism: the regulation of both gravity perception and response." article_processing_charge: No article_type: original author: - first_name: Yuzhou full_name: Zhang, Yuzhou id: 3B6137F2-F248-11E8-B48F-1D18A9856A87 last_name: Zhang orcid: 0000-0003-2627-6956 - first_name: P full_name: He, P last_name: He - first_name: X full_name: Ma, X last_name: Ma - first_name: Z full_name: Yang, Z last_name: Yang - first_name: C full_name: Pang, C last_name: Pang - first_name: J full_name: Yu, J last_name: Yu - first_name: G full_name: Wang, G last_name: Wang - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: G full_name: Xiao, G last_name: Xiao citation: ama: Zhang Y, He P, Ma X, et al.

Despite its importance, the regulation of PIN polar subcellular localization remains poorly understood. Here, we have employed advanced live-cell imaging techniques to study the roles of microtubules and actin microfilaments in the establishment of apical polar localization of PIN2 in the epidermis of the Arabidopsis root meristem.

Increased elongation growth of roots, hypocotyls and petioles in warm temperatures are hallmarks of seedling thermomorphogenesis. In the last decade, significant progress has been made to identify the molecular signaling components regulating these growth responses. Increased ambient temperature utilizes diverse components of the light sensing and signal transduction network to trigger growth adjustments. However, it remains unknown whether temperature sensing and responses are universal processes that occur uniformly in all plant organs. Alternatively, temperature sensing may be confined to specific tissues or organs, which would require a systemic signal that mediates responses in distal parts of the plant. Here we show that Arabidopsis (Arabidopsis thaliana) seedlings show organ-specific transcriptome responses to elevated temperatures, and that thermomorphogenesis involves both autonomous and organ-interdependent temperature sensing and signaling. Seedling roots can sense and respond to temperature in a shoot-independent manner, whereas shoot temperature responses require both local and systemic processes. The induction of cell elongation in hypocotyls requires temperature sensing in cotyledons, followed by generation of a mobile auxin signal. Subsequently, auxin travels to the hypocotyl where it triggers local brassinosteroid-induced cell elongation in seedling stems, which depends upon a distinct, permissive temperature sensor in the hypocotyl. article_processing_charge: No article_type: original author: - first_name: Julia full_name: Bellstaedt, Julia last_name: Bellstaedt - first_name: Jana full_name: Trenner, Jana last_name: Trenner - first_name: Rebecca full_name: Lippmann, Rebecca last_name: Lippmann - first_name: Yvonne full_name: Poeschl, Yvonne last_name: Poeschl - first_name: Xixi full_name: Zhang, Xixi id: 61A66458-47E9-11EA-85BA-8AEAAF14E49A last_name: Zhang orcid: 0000-0001-7048-4627 - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Marcel full_name: Quint, Marcel last_name: Quint - first_name: Carolin full_name: Delker, Carolin last_name: Delker citation: ama: Bellstaedt J, Trenner J, Lippmann R, et al.

Concentrations of auxin vary across different tissues, mediating distinct developmental outcomes and contributing to the functional diversity of auxin. However, the mechanisms that underlie these activities are poorly understood. Here we identify an auxin signalling mechanism, which acts in parallel to the canonical auxin pathway based on the transport inhibitor response1 (TIR1) and other auxin receptor F-box (AFB) family proteins (TIR1/AFB receptors)1,2, that translates levels of cellular auxin to mediate differential growth during apical-hook development. This signalling mechanism operates at the concave side of the apical hook, and involves auxin-mediated C-terminal cleavage of transmembrane kinase 1 (TMK1). The cytosolic and nucleus-translocated C terminus of TMK1 specifically interacts with and phosphorylates two non-canonical transcriptional repressors of the auxin or indole-3-acetic acid (Aux/IAA) family (IAA32 and IAA34), thereby regulating ARF transcription factors. In contrast to the degradation of Aux/IAA transcriptional repressors in the canonical pathway, the newly identified mechanism stabilizes the non-canonical IAA32 and IAA34 transcriptional repressors to regulate gene expression and ultimately inhibit growth. The auxin–TMK1 signalling pathway originates at the cell surface, is triggered by high levels of auxin and shares a partially overlapping set of transcription factors with the TIR1/AFB signalling pathway. This allows distinct interpretations of different concentrations of cellular auxin, and thus enables this versatile signalling molecule to mediate complex developmental outcomes. article_processing_charge: No article_type: original author: - first_name: Min full_name: Cao, Min last_name: Cao - first_name: Rong full_name: Chen, Rong last_name: Chen - first_name: Pan full_name: Li, Pan last_name: Li - first_name: Yongqiang full_name: Yu, Yongqiang last_name: Yu - first_name: Rui full_name: Zheng, Rui last_name: Zheng - first_name: Danfeng full_name: Ge, Danfeng last_name: Ge - first_name: Wei full_name: Zheng, Wei last_name: Zheng - first_name: Xuhui full_name: Wang, Xuhui last_name: Wang - first_name: Yangtao full_name: Gu, Yangtao last_name: Gu - first_name: Zuzana full_name: Gelová, Zuzana id: 0AE74790-0E0B-11E9-ABC7-1ACFE5697425 last_name: Gelová orcid: 0000-0003-4783-1752 - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Heng full_name: Zhang, Heng last_name: Zhang - first_name: Renyi full_name: Liu, Renyi last_name: Liu - first_name: Jun full_name: He, Jun last_name: He - first_name: Tongda full_name: Xu, Tongda last_name: Xu citation: ama: Cao M, Chen R, Li P, et al.

To elucidate the evolutionary origins of this developmentally crucial mechanism, we analysed the single PIN homologue of a simple green alga Klebsormidium flaccidum. KfPIN functions as a plasma membrane-localized auxin exporter in land plants and heterologous models. While its role in algae remains unclear, PIN-driven auxin export is probably an ancient and conserved trait within streptophytes. article_processing_charge: No article_type: original author: - first_name: Roman full_name: Skokan, Roman last_name: Skokan - first_name: Eva full_name: Medvecká, Eva last_name: Medvecká - first_name: Tom full_name: Viaene, Tom last_name: Viaene - first_name: Stanislav full_name: Vosolsobě, Stanislav last_name: Vosolsobě - first_name: Marta full_name: Zwiewka, Marta last_name: Zwiewka - first_name: Karel full_name: Müller, Karel last_name: Müller - first_name: Petr full_name: Skůpa, Petr last_name: Skůpa - first_name: Michal full_name: Karady, Michal last_name: Karady - first_name: Yuzhou full_name: Zhang, Yuzhou last_name: Zhang - first_name: Dorina P. full_name: Janacek, Dorina P. last_name: Janacek - first_name: Ulrich Z. full_name: Hammes, Ulrich Z. last_name: Hammes - first_name: Karin full_name: Ljung, Karin last_name: Ljung - first_name: Tomasz full_name: Nodzyński, Tomasz last_name: Nodzyński - first_name: Jan full_name: Petrášek, Jan last_name: Petrášek - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Skokan R, Medvecká E, Viaene T, et al.

Both the pathogen and the plant are under high selective pressure to rapidly adapt and co-evolve in what is usually referred to as molecular arms race. Components of the host’s immune system form a network that processes information about molecules with a foreign origin and damage-associated signals, integrating them with developmental and abiotic cues to adapt the plant’s responses. Both in the case of nucleotide-binding leucine-rich repeat receptors and leucine-rich repeat receptor kinases interaction networks have been extensively characterized. However, little is known on whether pathogenic effectors form complexes to overcome plant immunity and promote disease. Ustilago maydis, a biotrophic fungal pathogen that infects maize plants, produces effectors that target hubs in the immune network of the host cell. Here we assess the capability of U. maydis effector candidates to interact with each other, which may play a crucial role during the infection process. Using a systematic yeast-two-hybrid approach and based on a preliminary pooled screen, we selected 63 putative effectors for one-on-one matings with a library of nearly 300 effector candidates. We found that 126 of these effector candidates interacted either with themselves or other predicted effectors. Although the functional relevance of the observed interactions remains elusive, we propose that the observed abundance in complex formation between effectors adds an additional level of complexity to effector research and should be taken into consideration when studying effector evolution and function. Based on this fundamental finding, we suggest various scenarios which could evolutionarily drive the formation and stabilization of an effector interactome. article_number: '1437' article_processing_charge: No article_type: original author: - first_name: André full_name: Alcântara, André last_name: Alcântara - first_name: Jason full_name: Bosch, Jason last_name: Bosch - first_name: Fahimeh full_name: Nazari, Fahimeh last_name: Nazari - first_name: Gesa full_name: Hoffmann, Gesa last_name: Hoffmann - first_name: Michelle C full_name: Gallei, Michelle C id: 35A03822-F248-11E8-B48F-1D18A9856A87 last_name: Gallei orcid: 0000-0003-1286-7368 - first_name: Simon full_name: Uhse, Simon last_name: Uhse - first_name: Martin A. full_name: Darino, Martin A. last_name: Darino - first_name: Toluwase full_name: Olukayode, Toluwase last_name: Olukayode - first_name: Daniel full_name: Reumann, Daniel last_name: Reumann - first_name: Laura full_name: Baggaley, Laura last_name: Baggaley - first_name: Armin full_name: Djamei, Armin last_name: Djamei citation: ama: Alcântara A, Bosch J, Nazari F, et al.

In contrast, although small molecules can acutely and reversibly perturb CME, the few chemical CME inhibitors that have been applied to plants are either ineffective or show undesirable side effects. Here, we identify the previously described endosidin9 (ES9) as an inhibitor of clathrin heavy chain (CHC) function in both Arabidopsis and human cells through affinity-based target isolation, in vitro binding studies and X-ray crystallography. Moreover, we present a chemically improved ES9 analog, ES9-17, which lacks the undesirable side effects of ES9 while retaining the ability to target CHC. ES9 and ES9-17 have expanded the chemical toolbox used to probe CHC function, and present chemical scaffolds for further design of more specific and potent CHC inhibitors across different systems. article_processing_charge: No article_type: original author: - first_name: Wim full_name: Dejonghe, Wim last_name: Dejonghe - first_name: Isha full_name: Sharma, Isha last_name: Sharma - first_name: Bram full_name: Denoo, Bram last_name: Denoo - first_name: Steven full_name: De Munck, Steven last_name: De Munck - first_name: Qing full_name: Lu, Qing last_name: Lu - first_name: Kiril full_name: Mishev, Kiril last_name: Mishev - first_name: Haydar full_name: Bulut, Haydar last_name: Bulut - first_name: Evelien full_name: Mylle, Evelien last_name: Mylle - first_name: Riet full_name: De Rycke, Riet last_name: De Rycke - first_name: Mina K full_name: Vasileva, Mina K id: 3407EB18-F248-11E8-B48F-1D18A9856A87 last_name: Vasileva - first_name: Daniel V. full_name: Savatin, Daniel V. last_name: Savatin - first_name: Wim full_name: Nerinckx, Wim last_name: Nerinckx - first_name: An full_name: Staes, An last_name: Staes - first_name: Andrzej full_name: Drozdzecki, Andrzej last_name: Drozdzecki - first_name: Dominique full_name: Audenaert, Dominique last_name: Audenaert - first_name: Klaas full_name: Yperman, Klaas last_name: Yperman - first_name: Annemieke full_name: Madder, Annemieke last_name: Madder - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Daniël full_name: Van Damme, Daniël last_name: Van Damme - first_name: Kris full_name: Gevaert, Kris last_name: Gevaert - first_name: Volker full_name: Haucke, Volker last_name: Haucke - first_name: Savvas N. full_name: Savvides, Savvas N. last_name: Savvides - first_name: Johan full_name: Winne, Johan last_name: Winne - first_name: Eugenia full_name: Russinova, Eugenia last_name: Russinova citation: ama: Dejonghe W, Sharma I, Denoo B, et al.

An important role in these processes play the phytohormones and among them, auxin is crucial as it controls many important functions. It is transported through the whole plant body by creating local and temporal concentration maxima and minima, which have an impact on the cell status, tissue and organ identity. Auxin has the property to undergo a directional and finely regulated cell-to-cell transport, which is enabled by the transport proteins, localized on the plasma membrane. An important role in this process have the PIN auxin efflux proteins, which have an asymmetric/polar subcellular localization and determine the directionality of the auxin transport. During the last years, there were significant advances in understanding how the trafficking molecular machineries function, including studies on molecular interactions, function, subcellular localization and intracellular distribution. However, there is still a lack of detailed characterization on the steps of endocytosis, exocytosis, endocytic recycling and degradation. Due to this fact, I focused on the identification of novel trafficking factors and better characterization of the intracellular trafficking pathways. My PhD thesis consists of an introductory chapter, three experimental chapters, a chapter containing general discussion, conclusions and perspectives and also an appendix chapter with published collaborative papers.\r\nThe first chapter is separated in two different parts: I start by a general introduction to auxin biology and then I introduce the trafficking pathways in the model plant Arabidopsis thaliana. Then, I explain also the phosphorylation-signals for polar targeting and also the roles of the phytohormone strigolactone.\r\nThe second chapter includes the characterization of bar1/sacsin mutant, which was identified in a forward genetic screen for novel trafficking components in Arabidopsis thaliana, where by the implementation of an EMS-treated pPIN1::PIN1-GFP marker line and by using the established inhibitor of ARF-GEFs, Brefeldin A (BFA) as a tool to study trafficking processes, we identified a novel factor, which is mediating the adaptation of the plant cell to ARF-GEF inhibition. The mutation is in a previously uncharacterized gene, encoding a very big protein that we, based on its homologies, called SACSIN with domains suggesting roles as a molecular chaperon or as a component of the ubiquitin-proteasome system. Our physiology and imaging studies revealed that SACSIN is a crucial plant cell component of the adaptation to the ARF-GEF inhibition.\r\nThe third chapter includes six subchapters, where I focus on the role of the phytohormone strigolactone, which interferes with auxin feedback on PIN internalization. Strigolactone moderates the polar auxin transport by increasing the internalization of the PIN auxin efflux carriers, which reduces the canalization related growth responses. In addition, I also studied the role of phosphorylation in the strigolactone regulation of auxin feedback on PIN internalization. In this chapter I also present my results on the MAX2-dependence of strigolactone-mediated root growth inhibition and I also share my results on the auxin metabolomics profiling after application of GR24.\r\nIn the fourth chapter I studied the effect of two small molecules ES-9 and ES9-17, which were identified from a collection of small molecules with the property to impair the clathrin-mediated endocytosis.\r\nIn the fifth chapter, I discuss all my observations and experimental findings and suggest alternative hypothesis to interpret my results.\r\nIn the appendix there are three collaborative published projects. In the first, I participated in the characterization of the role of ES9 as a small molecule, which is inhibitor of clathrin- mediated endocytosis in different model organisms. In the second paper, I contributed to the characterization of another small molecule ES9-17, which is a non-protonophoric analog of ES9 and also impairs the clathrin-mediated endocytosis not only in plant cells, but also in mammalian HeLa cells. Last but not least, I also attach another paper, where I tried to establish the grafting method as a technique in our lab to study canalization related processes." acknowledged_ssus: - _id: LifeSc - _id: Bio alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Mina K full_name: Vasileva, Mina K id: 3407EB18-F248-11E8-B48F-1D18A9856A87 last_name: Vasileva citation: ama: Vasileva MK.

Plant cells have evolved diverse mechanisms to regulate PD plasticity in response to numerous environmental stimuli. In particular, during defense against plant pathogens, the defense hormone, salicylic acid (SA), plays a crucial role in the regulation of PD permeability in a callose-dependent manner. Here, we uncover a mechanism by which plants restrict the spreading of virus and PD cargoes using SA signaling by increasing lipid order and closure of PD. We showed that exogenous SA application triggered the compartmentalization of lipid raft nanodomains through a modulation of the lipid raft-regulatory protein, Remorin (REM). Genetic studies, superresolution imaging, and transmission electron microscopy observation together demonstrated that Arabidopsis REM1.2 and REM1.3 are crucial for plasma membrane nanodomain assembly to control PD aperture and functionality. In addition, we also found that a 14-3-3 epsilon protein modulates REM clustering and membrane nanodomain compartmentalization through its direct interaction with REM proteins. This study unveils a molecular mechanism by which the key plant defense hormone, SA, triggers membrane lipid nanodomain reorganization, thereby regulating PD closure to impede virus spreading. article_processing_charge: No article_type: original author: - first_name: D full_name: Huang, D last_name: Huang - first_name: Y full_name: Sun, Y last_name: Sun - first_name: Z full_name: Ma, Z last_name: Ma - first_name: M full_name: Ke, M last_name: Ke - first_name: Y full_name: Cui, Y last_name: Cui - first_name: Z full_name: Chen, Z last_name: Chen - first_name: C full_name: Chen, C last_name: Chen - first_name: C full_name: Ji, C last_name: Ji - first_name: TM full_name: Tran, TM last_name: Tran - first_name: L full_name: Yang, L last_name: Yang - first_name: SM full_name: Lam, SM last_name: Lam - first_name: Y full_name: Han, Y last_name: Han - first_name: G full_name: Shu, G last_name: Shu - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Y full_name: Miao, Y last_name: Miao - first_name: L full_name: Jiang, L last_name: Jiang - first_name: X full_name: Chen, X last_name: Chen citation: ama: Huang D, Sun Y, Ma Z, et al.

The main aim of my thesis is to decipher the basic mechanisms of CME and post-endocytic trafficking in the whole multicellular organ systems of Arabidopsis. The first chapter of my thesis describes the search for new components involved in CME. Tandem affinity purification was conducted using CLC and its interacting partners were identified. Amongst the identified proteins were the Auxilin-likes1 and 2 (Axl1/2), putative uncoating factors, for which we made a full functional analysis. Over-expression of Axl1/2 causes extreme modifications in the dynamics of the machinery proteins and inhibition of endocytosis altogether. However the loss of function of the axl1/2 did not present any cellular or physiological phenotype, meaning Auxilin-likes do not form the major uncoating machinery. The second chapter of my thesis describes the establishment/utilisation of techniques to capture the dynamicity and the complexity of CME and post-endocytic trafficking. We have studied the development of endocytic pits at the PM – specifically, the mode of membrane remodeling during pit development and the role of actin in it, given plant cells possess high turgor pressure. Utilizing the improved z-resolution of TIRF and VAEM techniques, we captured the time-lapse of the endocytic events at the plasma membrane; and using particle detection software, we quantitatively analysed all the endocytic trajectories in an unbiased way to obtain the endocytic rate of the system. This together with the direct analysis of cargo internalisation from the PM provided an estimate on the endocytic potential of the cell. We also developed a methodology for ultrastructural analysis of different populations of Clathrin-Coated Structures (CCSs) in both PM and endomembranes in unroofed protoplasts. Structural analysis, together with the intensity profile of CCSs at the PM show that the mode of CCP development at the PM follows ‘Constant curvature model’; meaning that clathrin polymerisation energy is a major contributing factor of membrane remodeling. In addition, other analyses clearly show that actin is not required for membrane remodeling during invagination or any other step of CCP development, despite the prevalent high turgor pressure. However, actin is essential in orchestrating the post-endocytic trafficking of CCVs facilitating the EE formation. We also observed that the uncoating process post-endocytosis is not immediate; an alternative mechanism of uncoating – Sequential multi-step process – functions in the cell. Finally we also looked at one of the important physiological stimuli modulating the process – hormone, auxin. auxin has been known to influence CME before. We have made a detailed study on the concentration-time based effect of auxin on the machinery proteins, CCP development, and the specificity of cargoes endocytosed. To this end, we saw no general effect of auxin on CME at earlier time points. However, very low concentration of IAA, such as 50nM, accelerates endocytosis of specifically PIN2 through CME. Such a tight regulatory control with high specificity to PIN2 could be essential in modulating its polarity.

lang: eng text: "A process of restorative patterning in plant roots correctly replaces eliminated cells to heal local injuries despite the absence of cell migration, which underpins wound healing in animals. \r\n\r\nPatterning in plants relies on oriented cell divisions and acquisition of specific cell identities. Plants regularly endure wounds caused by abiotic or biotic environmental stimuli and have developed extraordinary abilities to restore their tissues after injuries. Here, we provide insight into a mechanism of restorative patterning that repairs tissues after wounding. Laser-assisted elimination of different cells in Arabidopsis root combined with live-imaging tracking during vertical growth allowed analysis of the regeneration processes in vivo. Specifically, the cells adjacent to the inner side of the injury re-activated their stem cell transcriptional programs. They accelerated their progression through cell cycle, coordinately changed the cell division orientation, and ultimately acquired de novo the correct cell fates to replace missing cells. These observations highlight existence of unknown intercellular positional signaling and demonstrate the capability of specified cells to re-acquire stem cell programs as a crucial part of the plant-specific mechanism of wound healing." acknowledged_ssus: - _id: Bio article_processing_charge: No author: - first_name: Petra full_name: Marhavá, Petra id: 44E59624-F248-11E8-B48F-1D18A9856A87 last_name: Marhavá - first_name: Lukas full_name: Hörmayer, Lukas id: 2EEE7A2A-F248-11E8-B48F-1D18A9856A87 last_name: Hörmayer orcid: 0000-0001-8295-2926 - first_name: Saiko full_name: Yoshida, Saiko id: 2E46069C-F248-11E8-B48F-1D18A9856A87 last_name: Yoshida - first_name: Peter full_name: Marhavy, Peter id: 3F45B078-F248-11E8-B48F-1D18A9856A87 last_name: Marhavy orcid: 0000-0001-5227-5741 - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Marhavá P, Hörmayer L, Yoshida S, Marhavý P, Benková E, Friml J.

These challenges often lead to the induction of wounds or destruction of already specified and developed tissues. Additionally, wounding makes plants vulnerable to invasion by pathogens, which is why wound signalling often triggers specific defence responses. To stay competitive or, eventually, survive under these circumstances, plants need to regenerate efficiently, which in rigid, tissue migration-incompatible plant tissues requires post-embryonic patterning and organogenesis. Now, several studies used laser-assisted single cell ablation in the Arabidopsis root tip as a minimal wounding proxy. Here, we discuss their findings and put them into context of a broader spectrum of wound signalling, pathogen responses and tissue as well as organ regeneration. article_processing_charge: No article_type: original author: - first_name: Lukas full_name: Hörmayer, Lukas id: 2EEE7A2A-F248-11E8-B48F-1D18A9856A87 last_name: Hörmayer orcid: 0000-0001-8295-2926 - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Hörmayer L, Friml J.

PIN auxin efflux carriers regulate directional auxin movement by establishing local auxin maxima, minima, and gradients that drive multiple developmental processes and responses to environmental signals. Auxin has been proposed to modulate its own transport by regulating subcellular PIN trafficking via processes such as clathrin-mediated PIN endocytosis and constitutive recycling. Here, we further investigated the mechanisms by which auxin affects PIN trafficking by screening auxin analogs and identified pinstatic acid (PISA) as a positive modulator of polar auxin transport in Arabidopsis thaliana. PISA had an auxin-like effect on hypocotyl elongation and adventitious root formation via positive regulation of auxin transport. PISA did not activate SCFTIR1/AFB signaling and yet induced PIN accumulation at the cell surface by inhibiting PIN internalization from the plasma membrane. This work demonstrates PISA to be a promising chemical tool to dissect the regulatory mechanisms behind subcellular PIN trafficking and auxin transport. acknowledgement: "We thank Dr. H.

Factors regulating plant growth, among them the hormone auxin, have been recognized as regulators of microtubule array orientations. Some previous work in the field has aimed at elucidating the causal relationship between cell growth, the signaling of auxin or other growth-regulating factors, and microtubule array reorientations, with various conclusions. Here, we revisit this problem of causality with a comprehensive set of experiments in Arabidopsis thaliana, using the now available pharmacological and genetic tools. We use isolated, auxin-depleted hypocotyls, an experimental system allowing for full control of both growth and auxin signaling. We demonstrate that reorientation of microtubules is not directly triggered by an auxin signal during growth activation. Instead, reorientation is triggered by the activation of the growth process itself and is auxin-independent in its nature. We discuss these findings in the context of previous relevant work, including that on the mechanical regulation of microtubule array orientation. article_number: '3337' article_processing_charge: Yes article_type: original author: - first_name: Maciek full_name: Adamowski, Maciek id: 45F536D2-F248-11E8-B48F-1D18A9856A87 last_name: Adamowski orcid: 0000-0001-6463-5257 - first_name: Lanxin full_name: Li, Lanxin id: 367EF8FA-F248-11E8-B48F-1D18A9856A87 last_name: Li orcid: 0000-0002-5607-272X - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Adamowski M, Li L, Friml J.

The plant tissue origin and the method by which they are induced determine the physiological properties of emerged ARs. Hence, a standard method encompassing all types of AR does not exist. Here we describe a method for the induction and analysis of AR that emerge from the etiolated hypocotyl of dicot plants. The hypocotyl is formed during embryogenesis and shows a determined developmental pattern which usually does not involve AR formation. However, the hypocotyl shows propensity to form de novo roots under specific circumstances such as removal of the root system, high humidity or flooding, or during de-etiolation. The hypocotyl AR emerge from a pericycle-like cell layer surrounding the vascular tissue of the central cylinder, which is reminiscent to the developmental program of lateral roots. Here we propose an easy protocol for in vitro hypocotyl AR induction from etiolated Arabidopsis seedlings. alternative_title: - MIMB article_processing_charge: No author: - first_name: Hoang full_name: Trinh, Hoang last_name: Trinh - first_name: Inge full_name: Verstraeten, Inge id: 362BF7FE-F248-11E8-B48F-1D18A9856A87 last_name: Verstraeten orcid: 0000-0001-7241-2328 - first_name: Danny full_name: Geelen, Danny last_name: Geelen citation: ama: 'Trinh H, Verstraeten I, Geelen D.

In plants, whole-mount in situ immunolocalization remains a challenging method, especially in tissues protected by waxy layers and complex cell wall carbohydrates. Here, we present a robust method for whole-mount in situ immunolocalization in primary root meristems and lateral root primordia in Arabidopsis thaliana. For good epitope preservation, fixation is done in an alkaline paraformaldehyde/glutaraldehyde mixture. This fixative is suitable for detecting a wide range of proteins, including integral transmembrane proteins and proteins peripherally attached to the plasma membrane. From initiation until emergence from the primary root, lateral root primordia are surrounded by several layers of differentiated tissues with a complex cell wall composition that interferes with the efficient penetration of all buffers. Therefore, immunolocalization in early lateral root primordia requires a modified method, including a strong solvent treatment for removal of hydrophobic barriers and a specific cocktail of cell wall-degrading enzymes. The presented method allows for easy, reliable, and high-quality in situ detection of the subcellular localization of endogenous proteins in primary and lateral root meristems without the need of time-consuming crosses or making translational fusions to fluorescent proteins. alternative_title: - Methods in Molecular Biology author: - first_name: Michael full_name: Karampelias, Michael last_name: Karampelias - first_name: Ricardo full_name: Tejos, Ricardo last_name: Tejos - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Steffen full_name: Vanneste, Steffen last_name: Vanneste citation: ama: 'Karampelias M, Tejos R, Friml J, Vanneste S.

Local differences in auxin concentrations are achieved mainly by polarized cellular distribution of PIN auxin transporters, but whether other mechanisms involving auxin homeostasis are also relevant for the formation of auxin gradients is not clear. Here we show that auxin methylation is required for asymmetric auxin distribution across the hypocotyl, particularly during its response to gravity. We found that loss-of-function mutants in Arabidopsis IAA CARBOXYL METHYLTRANSFERASE1 (IAMT1) prematurely unfold the apical hook, and that their hypocotyls are impaired in gravitropic reorientation. This defect is linked to an auxin-dependent increase in PIN gene expression, leading to an increased polar auxin transport and lack of asymmetric distribution of PIN3 in the iamt1 mutant. Gravitropic reorientation in the iamt1 mutant could be restored with either endodermis-specific expression of IAMT1 or partial inhibition of polar auxin transport, which also results in normal PIN gene expression levels. We propose that IAA methylation is necessary in gravity-sensing cells to restrict polar auxin transport within the range of auxin levels that allow for differential responses. article_processing_charge: No author: - first_name: Mohamad full_name: Abbas, Mohamad id: 47E8FC1C-F248-11E8-B48F-1D18A9856A87 last_name: Abbas - first_name: García J full_name: Hernández, García J last_name: Hernández - first_name: Stephan full_name: Pollmann, Stephan last_name: Pollmann - first_name: Sophia L full_name: Samodelov, Sophia L last_name: Samodelov - first_name: Martina full_name: Kolb, Martina last_name: Kolb - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Ulrich Z full_name: Hammes, Ulrich Z last_name: Hammes - first_name: Matias D full_name: Zurbriggen, Matias D last_name: Zurbriggen - first_name: Miguel full_name: Blázquez, Miguel last_name: Blázquez - first_name: David full_name: Alabadí, David last_name: Alabadí citation: ama: Abbas M, Hernández GJ, Pollmann S, et al.

However, the biological relevance of most CLE genes remains to be functionally characterized. Here, we report that CLE9, which is expressed in stomata, acts as an essential regulator in the induction of stomatal closure. Exogenous application of CLE9 peptides or overexpression of CLE9 effectively led to stomatal closure and enhanced drought tolerance, whereas CLE9 loss-of-function mutants were sensitivity to drought stress. CLE9-induced stomatal closure was impaired in abscisic acid (ABA)-deficient mutants, indicating that ABA is required for CLE9-medaited guard cell signalling. We further deciphered that two guard cell ABA-signalling components, OST1 and SLAC1, were responsible for CLE9-induced stomatal closure. MPK3 and MPK6 were activated by the CLE9 peptide, and CLE9 peptides failed to close stomata in mpk3 and mpk6 mutants. In addition, CLE9 peptides stimulated the induction of hydrogen peroxide (H2O2) and nitric oxide (NO) synthesis associated with stomatal closure, which was abolished in the NADPH oxidase-deficient mutants or nitric reductase mutants, respectively. Collectively, our results reveal a novel ABA-dependent function of CLE9 in the regulation of stomatal apertures, thereby suggesting a potential role of CLE9 in the stress acclimatization of plants. article_processing_charge: No author: - first_name: Luosha full_name: Zhang, Luosha last_name: Zhang - first_name: Xiong full_name: Shi, Xiong last_name: Shi - first_name: Yutao full_name: Zhang, Yutao last_name: Zhang - first_name: Jiajing full_name: Wang, Jiajing last_name: Wang - first_name: Jingwei full_name: Yang, Jingwei last_name: Yang - first_name: Takashi full_name: Ishida, Takashi last_name: Ishida - first_name: Wenqian full_name: Jiang, Wenqian last_name: Jiang - first_name: Xiangyu full_name: Han, Xiangyu last_name: Han - first_name: Jingke full_name: Kang, Jingke last_name: Kang - first_name: Xuening full_name: Wang, Xuening last_name: Wang - first_name: Lixia full_name: Pan, Lixia last_name: Pan - first_name: Shuo full_name: Lv, Shuo last_name: Lv - first_name: Bing full_name: Cao, Bing last_name: Cao - first_name: Yonghong full_name: Zhang, Yonghong last_name: Zhang - first_name: Jinbin full_name: Wu, Jinbin last_name: Wu - first_name: Huibin full_name: Han, Huibin id: 31435098-F248-11E8-B48F-1D18A9856A87 last_name: Han - first_name: Zhubing full_name: Hu, Zhubing last_name: Hu - first_name: Langjun full_name: Cui, Langjun last_name: Cui - first_name: Shinichiro full_name: Sawa, Shinichiro last_name: Sawa - first_name: Junmin full_name: He, Junmin last_name: He - first_name: Guodong full_name: Wang, Guodong last_name: Wang citation: ama: Zhang L, Shi X, Zhang Y, et al.

The main paradigm of GA signaling puts forward transcriptional regulation via the degradation of DELLA transcriptional repressors. GA has also been shown to regulate tropic responses by modulation of the plasma membrane incidence of PIN auxin transporters by an unclear mechanism. Here we uncovered the cellular and molecular mechanisms by which GA redirects protein trafficking and thus regulates cell surface functionality. Photoconvertible reporters revealed that GA balances the protein traffic between the vacuole degradation route and recycling back to the cell surface. Low GA levels promote vacuolar delivery and degradation of multiple cargos, including PIN proteins, whereas high GA levels promote their recycling to the plasma membrane. This GA effect requires components of the retromer complex, such as Sorting Nexin 1 (SNX1) and its interacting, microtubule (MT)-associated protein, the Cytoplasmic Linker-Associated Protein (CLASP1). Accordingly, GA regulates the subcellular distribution of SNX1 and CLASP1, and the intact MT cytoskeleton is essential for the GA effect on trafficking. This GA cellular action occurs through DELLA proteins that regulate the MT and retromer presumably via their interaction partners Prefoldins (PFDs). Our study identified a branching of the GA signaling pathway at the level of DELLA proteins, which, in parallel to regulating transcription, also target by a nontranscriptional mechanism the retromer complex acting at the intersection of the degradation and recycling trafficking routes. By this mechanism, GA can redirect receptors and transporters to the cell surface, thus coregulating multiple processes, including PIN-dependent auxin fluxes during tropic responses. acknowledgement: "We gratefully acknowledge M.

The stigma tissue plays a key role in flower receptivity by intercepting pollen and initiating pollen tube growth toward the ovary. In this article, we show that a developmentally controlled cell death programme terminates the functional life span of stigma cells in Arabidopsis. We identified the leaf senescence regulator ORESARA1 (also known as ANAC092) and the previously uncharacterized KIRA1 (also known as ANAC074) as partially redundant transcription factors that modulate stigma longevity by controlling the expression of programmed cell death-associated genes. KIRA1 expression is sufficient to induce cell death and terminate floral receptivity, whereas lack of both KIRA1 and ORESARA1 substantially increases stigma life span. Surprisingly, the extension of stigma longevity is accompanied by only a moderate extension of flower receptivity, suggesting that additional processes participate in the control of the flower's receptive life span. acknowledgement: We gratefully acknowledge funding from the Chinese Scholarship Council (CSC; project number 201206910025 to Z.G.), the Fonds Wetenschappelijk Onderzoek (FWO; project number G005112N to A.D.; fellowship number 12I7417N to Z.L.), the Belgian Federal Science Policy Office (BELSPO; to Y.S.), the Agency for Innovation by Science and Technology of Belgium (IWT; fellowship number 121110 to M.V.D.), the Hercules foundation (grant AUGE-09-029 to K.D.), and the ERC StG PROCELLDEATH (project number 639234 to M.K.N.). article_processing_charge: No author: - first_name: Zhen full_name: Gao, Zhen last_name: Gao - first_name: Anna full_name: Daneva, Anna last_name: Daneva - first_name: Yuliya full_name: Salanenka, Yuliya id: 46DAAE7E-F248-11E8-B48F-1D18A9856A87 last_name: Salanenka - first_name: Matthias full_name: Van Durme, Matthias last_name: Van Durme - first_name: Marlies full_name: Huysmans, Marlies last_name: Huysmans - first_name: Zongcheng full_name: Lin, Zongcheng last_name: Lin - first_name: Freya full_name: De Winter, Freya last_name: De Winter - first_name: Steffen full_name: Vanneste, Steffen last_name: Vanneste - first_name: Mansour full_name: Karimi, Mansour last_name: Karimi - first_name: Jan full_name: Van De Velde, Jan last_name: Van De Velde - first_name: Klaas full_name: Vandepoele, Klaas last_name: Vandepoele - first_name: Davy full_name: Van De Walle, Davy last_name: Van De Walle - first_name: Koen full_name: Dewettinck, Koen last_name: Dewettinck - first_name: Bart full_name: Lambrecht, Bart last_name: Lambrecht - first_name: Moritz full_name: Nowack, Moritz last_name: Nowack citation: ama: Gao Z, Daneva A, Salanenka Y, et al.

At the onset of embryo development in Arabidopsis thaliana, the zygote divides asymmetrically, producing a small apical embryonic cell and a larger basal cell that connects the embryo to the maternal tissue2. The coordinated and synchronous development of the embryo and the surrounding integuments, and the alignment of their growth axes, suggest communication between maternal tissues and the embryo. In contrast to animals, however, where a network of maternal factors that direct embryo patterning have been identified3,4, only a few maternal mutations have been described to affect embryo development in plants5–7. Early embryo patterning in Arabidopsis requires accumulation of the phytohormone auxin in the apical cell by directed transport from the suspensor8–10. However, the origin of this auxin has remained obscure. Here we investigate the source of auxin for early embryogenesis and provide evidence that the mother plant coordinates seed development by supplying auxin to the early embryo from the integuments of the ovule. We show that auxin response increases in ovules after fertilization, due to upregulated auxin biosynthesis in the integuments, and this maternally produced auxin is required for correct embryo development.' acknowledgement: This work was further supported by the Czech Science Foundation GACR (GA13-40637S) to J.F.; article_processing_charge: No author: - first_name: Hélène full_name: Robert, Hélène last_name: Robert - first_name: Chulmin full_name: Park, Chulmin last_name: Park - first_name: Carla full_name: Gutièrrez, Carla last_name: Gutièrrez - first_name: Barbara full_name: Wójcikowska, Barbara last_name: Wójcikowska - first_name: Aleš full_name: Pěnčík, Aleš last_name: Pěnčík - first_name: Ondřej full_name: Novák, Ondřej last_name: Novák - first_name: Junyi full_name: Chen, Junyi last_name: Chen - first_name: Wim full_name: Grunewald, Wim last_name: Grunewald - first_name: Thomas full_name: Dresselhaus, Thomas last_name: Dresselhaus - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Thomas full_name: Laux, Thomas last_name: Laux citation: ama: Robert H, Park C, Gutièrrez C, et al.

Here, we report that AtNHX5 and AtNHX6, functioning as H+ leak, control auxin homeostasis and auxin-mediated development. We found that nhx5 nhx6 exhibited growth variations of auxin-related defects. We further showed that nhx5 nhx6 was affected in auxin homeostasis. Genetic analysis showed that AtNHX5 and AtNHX6 were required for the function of the ER-localized auxin transporter PIN5. Although AtNHX5 and AtNHX6 were co-localized with PIN5 at ER, they did not interact directly. Instead, the conserved acidic residues in AtNHX5 and AtNHX6, which are essential for exchange activity, were required for PIN5 function. AtNHX5 and AtNHX6 regulated the pH in ER. Overall, AtNHX5 and AtNHX6 may regulate auxin transport across the ER via the pH gradient created by their transport activity. H+-leak pathway provides a fine-tuning mechanism that controls cellular auxin fluxes.

It has been firmly established that canonical, nuclear auxin signalling acts through regulation of gene transcription(2). Here, we combined microfluidics, live imaging, genetic engineering and computational modelling to reanalyse the classical case of root growth inhibition(3) by auxin. We show that Arabidopsis roots react to addition and removal of auxin by extremely rapid adaptation of growth rate. This process requires intracellular auxin perception but not transcriptional reprogramming. The formation of the canonical TIR1/AFB-Aux/IAA co-receptor complex is required for the growth regulation, hinting to a novel, non-transcriptional branch of this signalling pathway. Our results challenge the current understanding of root growth regulation by auxin and suggest another, presumably non-transcriptional, signalling output of the canonical auxin pathway. article_processing_charge: No article_type: original author: - first_name: Matyas full_name: Fendrych, Matyas id: 43905548-F248-11E8-B48F-1D18A9856A87 last_name: Fendrych orcid: 0000-0002-9767-8699 - first_name: Maria full_name: Akhmanova, Maria id: 3425EC26-F248-11E8-B48F-1D18A9856A87 last_name: Akhmanova orcid: 0000-0003-1522-3162 - first_name: Jack full_name: Merrin, Jack id: 4515C308-F248-11E8-B48F-1D18A9856A87 last_name: Merrin orcid: 0000-0001-5145-4609 - first_name: Matous full_name: Glanc, Matous last_name: Glanc - first_name: Shinya full_name: Hagihara, Shinya last_name: Hagihara - first_name: Koji full_name: Takahashi, Koji last_name: Takahashi - first_name: Naoyuki full_name: Uchida, Naoyuki last_name: Uchida - first_name: Keiko U full_name: Torii, Keiko U last_name: Torii - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Fendrych M, Akhmanova M, Merrin J, et al.

PINs are localized at the plasma membrane (PM) and on constitutively recycling endomembrane vesicles. Therefore, PINs can mediate auxin transport either by direct translocation across the PM or by pumping auxin into secretory vesicles (SVs), leading to its secretory release upon fusion with the PM. Which of these two mechanisms dominates is a matter of debate. Here, we addressed the issue with a mathematical modeling approach. We demonstrate that the efficiency of secretory transport depends on SV size, half-life of PINs on the PM, pH, exocytosis frequency and PIN density. 3D structured illumination microscopy (SIM) was used to determine PIN density on the PM. Combining this data with published values of the other parameters, we show that the transport activity of PINs in SVs would have to be at least 1000× greater than on the PM in order to produce a comparable macroscopic auxin transport. If both transport mechanisms operated simultaneously and PINs were equally active on SVs and PM, the contribution of secretion to the total auxin flux would be negligible. In conclusion, while secretory vesicle-mediated transport of auxin is an intriguing and theoretically possible model, it is unlikely to be a major mechanism of auxin transport inplanta. acknowledgement: 'European Research Council (ERC): 742985 to Jiri Friml; M.A. was supported by the Austrian Science Fund (FWF) (M2379-B28); AJ was supported by the Austria Science Fund (FWF): I03630 to Jiri Friml.' article_processing_charge: No article_type: original author: - first_name: Sander full_name: Hille, Sander last_name: Hille - first_name: Maria full_name: Akhmanova, Maria id: 3425EC26-F248-11E8-B48F-1D18A9856A87 last_name: Akhmanova orcid: 0000-0003-1522-3162 - first_name: Matous full_name: Glanc, Matous id: 1AE1EA24-02D0-11E9-9BAA-DAF4881429F2 last_name: Glanc orcid: 0000-0003-0619-7783 - first_name: Alexander J full_name: Johnson, Alexander J id: 46A62C3A-F248-11E8-B48F-1D18A9856A87 last_name: Johnson orcid: 0000-0002-2739-8843 - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: 'Hille S, Akhmanova M, Glanc M, Johnson AJ, Friml J.

However, this crop is very sensitive to temperature changes. Specifically, processes during wheat leaf, flower, and seed development and photosynthesis, which all contribute to the yield of this crop, are affected by high temperature. While this has to some extent been investigated on physiological, developmental, and molecular levels, very little is known about early signalling events associated with an increase in temperature. Phosphorylation-mediated signalling mechanisms, which are quick and dynamic, are associated with plant growth and development, also under abiotic stress conditions. Therefore, we probed the impact of a short-term and mild increase in temperature on the wheat leaf and spikelet phosphoproteome. In total, 3822 (containing 5178 phosphosites) and 5581 phosphopeptides (containing 7023 phosphosites) were identified in leaf and spikelet samples, respectively. Following statistical analysis, the resulting data set provides the scientific community with a first large-scale plant phosphoproteome under the control of higher ambient temperature. This community resource on the high temperature-mediated wheat phosphoproteome will be valuable for future studies. Our analyses also revealed a core set of common proteins between leaf and spikelet, suggesting some level of conserved regulatory mechanisms. Furthermore, we observed temperature-regulated interconversion of phosphoforms, which probably impacts protein activity. acknowledgement: TZ is supported by a grant from the Chinese Scholarship Council. article_processing_charge: No author: - first_name: Lam full_name: Vu, Lam last_name: Vu - first_name: Tingting full_name: Zhu, Tingting last_name: Zhu - first_name: Inge full_name: Verstraeten, Inge id: 362BF7FE-F248-11E8-B48F-1D18A9856A87 last_name: Verstraeten orcid: 0000-0001-7241-2328 - first_name: Brigitte full_name: Van De Cotte, Brigitte last_name: Van De Cotte - first_name: Kris full_name: Gevaert, Kris last_name: Gevaert - first_name: Ive full_name: De Smet, Ive last_name: De Smet citation: ama: Vu L, Zhu T, Verstraeten I, Van De Cotte B, Gevaert K, De Smet I.

In plants, ARF-GEFs play essential roles in endocytosis, vacuolar trafficking, recycling, secretion, and polar trafficking. Moreover, they are important for plant development, mainly through controlling the polar subcellular localization of PIN-FORMED (PIN) transporters of the plant hormone auxin. Here, using a chemical genetics screen in Arabidopsis thaliana, we identified Endosidin 4 (ES4), an inhibitor of eukaryotic ARF-GEFs. ES4 acts similarly to and synergistically with the established ARF-GEF inhibitor Brefeldin A and has broad effects on intracellular trafficking, including endocytosis, exocytosis, and vacuolar targeting. Additionally, Arabidopsis and yeast (Sacharomyces cerevisiae) mutants defective in ARF-GEF show altered sensitivity to ES4. ES4 interferes with the activation-based membrane association of the ARF1 GTPases, but not of their mutant variants that are activated independently of ARF-GEF activity. Biochemical approaches and docking simulations confirmed that ES4 specifically targets the SEC7 domain-containing ARF-GEFs. These observations collectively identify ES4 as a chemical tool enabling the study of ARF-GEF-mediated processes, including ARF-GEF-mediated plant development. acknowledgement: We thank Gerd Jürgens, Sandra Richter, and Sheng Yang He for providing antibodies; Maciek Adamowski, Fernando Aniento, Sebastian Bednarek, Nico Callewaert, Matyás Fendrych, Elena Feraru, and Mugurel I.

In Arabidopsis, lateral root cap (LRC) cells covering the meristematic zone are regularly lost through programmed cell death, while the outermost layer of the root cap covering the tip is repeatedly sloughed. Efficient coordination with stem cells producing new layers is needed to maintain a constant size of the cap. We present a signalling pair, the peptide IDA-LIKE1 (IDL1) and its receptor HAESA-LIKE2 (HSL2), mediating such communication. Live imaging over several days characterized this process from initial fractures in LRC cell files to full separation of a layer. Enhanced expression of IDL1 in the separating root cap layers resulted in increased frequency of sloughing, balanced with generation of new layers in a HSL2-dependent manner. Transcriptome analyses linked IDL1-HSL2 signalling to the transcription factors BEARSKIN1/2 and genes associated with programmed cell death. Mutations in either IDL1 or HSL2 slowed down cell division, maturation and separation. Thus, IDL1-HSL2 signalling potentiates dynamic regulation of the homeostatic balance between stem cell division and sloughing activity. article_processing_charge: No article_type: original author: - first_name: Chun Lin full_name: Shi, Chun Lin last_name: Shi - first_name: Daniel full_name: Von Wangenheim, Daniel id: 49E91952-F248-11E8-B48F-1D18A9856A87 last_name: Von Wangenheim orcid: 0000-0002-6862-1247 - first_name: Ullrich full_name: Herrmann, Ullrich last_name: Herrmann - first_name: Mari full_name: Wildhagen, Mari last_name: Wildhagen - first_name: Ivan full_name: Kulik, Ivan id: F0AB3FCE-02D1-11E9-BD0E-99399A5D3DEB last_name: Kulik - first_name: Andreas full_name: Kopf, Andreas last_name: Kopf - first_name: Takashi full_name: Ishida, Takashi last_name: Ishida - first_name: Vilde full_name: Olsson, Vilde last_name: Olsson - first_name: Mari Kristine full_name: Anker, Mari Kristine last_name: Anker - first_name: Markus full_name: Albert, Markus last_name: Albert - first_name: Melinka A full_name: Butenko, Melinka A last_name: Butenko - first_name: Georg full_name: Felix, Georg last_name: Felix - first_name: Shinichiro full_name: Sawa, Shinichiro last_name: Sawa - first_name: Manfred full_name: Claassen, Manfred last_name: Claassen - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Reidunn B full_name: Aalen, Reidunn B last_name: Aalen citation: ama: Shi CL, von Wangenheim D, Herrmann U, et al.

SL signalling is perceived by an α/β hydrolase, DWARF 14 (D14). A close homolog of D14, KARRIKIN INSENSTIVE2 (KAI2), is involved in perception of an uncharacterized molecule called karrikin (KAR). Recent studies in Arabidopsis identified the SUPPRESSOR OF MAX2 1 (SMAX1) and SMAX1-LIKE 7 (SMXL7) to be potential SCF–MAX2 complex-mediated proteasome targets of KAI2 and D14, respectively. Genetic studies on SMXL7 and SMAX1 demonstrated distinct developmental roles for each, but very little is known about these repressors in terms of their sequence features. In this study, we performed an extensive comparative analysis of SMXLs and determined their phylogenetic and evolutionary history in the plant lineage. Our results show that SMXL family members can be sub-divided into four distinct phylogenetic clades/classes, with an ancient SMAX1. Further, we identified the clade-specific motifs that have evolved and that might act as determinants of SL-KAR signalling specificity. These specificities resulted from functional diversities among the clades. Our results suggest that a gradual co-evolution of SMXL members with their upstream receptors D14/KAI2 provided an increased specificity to both the SL perception and response in land plants. acknowledgement: "This project received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Actions and it is co-financed by the South Moravian Region under grant agreement No. 665860 (SS).

In plants, a directional distribution of the plant hormone auxin is at the core of many developmental programs. A feedback regulation of auxin on the polarized localization of PIN auxin transporters in individual cells has been proposed as a self-organizing mechanism for coordinated tissue polarization, but the molecular mechanisms linking auxin signalling to PIN-dependent auxin transport remain unknown. We performed a microarray-based approach to find regulators of the auxin-induced PIN relocation in the Arabidopsis thaliana root. We identified a subset of a family of phosphatidylinositol transfer proteins (PITP), the PATELLINs (PATL). Here, we show that PATLs are expressed in partially overlapping cells types in different tissues going through mitosis or initiating differentiation programs. PATLs are plasma membrane-associated proteins accumulated in Arabidopsis embryos, primary roots, lateral root primordia, and developing stomata. Higher order patl mutants display reduced PIN1 repolarization in response to auxin, shorter root apical meristem, and drastic defects in embryo and seedling development. This suggests PATLs redundantly play a crucial role in polarity and patterning in Arabidopsis. article_number: jcs.204198 article_processing_charge: No author: - first_name: Ricardo full_name: Tejos, Ricardo last_name: Tejos - first_name: Cecilia full_name: Rodríguez Furlán, Cecilia last_name: Rodríguez Furlán - first_name: Maciek full_name: Adamowski, Maciek id: 45F536D2-F248-11E8-B48F-1D18A9856A87 last_name: Adamowski orcid: 0000-0001-6463-5257 - first_name: Michael full_name: Sauer, Michael last_name: Sauer - first_name: Lorena full_name: Norambuena, Lorena last_name: Norambuena - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Tejos R, Rodríguez Furlán C, Adamowski M, Sauer M, Norambuena L, Friml J.

In plants, PIN auxin transporters are prominent polarity markers crucial for a plethora of developmental processes. Cell polarity mechanisms in plants are distinct from other eukaryotes and still largely elusive. In particular, how the cell polarities are propagated and maintained following cell division remains unknown. Plant cytokinesis is orchestrated by the cell plate—a transient centrifugally growing endomembrane compartment ultimately forming the cross wall1. Trafficking of polar membrane proteins is typically redirected to the cell plate, and these will consequently have opposite polarity in at least one of the daughter cells2–5. Here, we provide mechanistic insights into post-cytokinetic re-establishment of cell polarity as manifested by the apical, polar localization of PIN2. We show that the apical domain is defined in a cell-intrinsic manner and that re-establishment of PIN2 localization to this domain requires de novo protein secretion and endocytosis, but not basal-to-apical transcytosis. Furthermore, we identify a PINOID-related kinase WAG1, which phosphorylates PIN2 in vitro6 and is transcriptionally upregulated specifically in dividing cells, as a crucial regulator of post-cytokinetic PIN2 polarity re-establishment. article_processing_charge: No author: - first_name: Matous full_name: Glanc, Matous id: 1AE1EA24-02D0-11E9-9BAA-DAF4881429F2 last_name: Glanc orcid: 0000-0003-0619-7783 - first_name: Matyas full_name: Fendrych, Matyas id: 43905548-F248-11E8-B48F-1D18A9856A87 last_name: Fendrych orcid: 0000-0002-9767-8699 - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Glanc M, Fendrych M, Friml J.

CME is essential for many developmental and physiological processes in plants, but its underlying mechanism is not well characterised compared to that in yeast and animal systems. Here, we searched for new factors involved in CME in Arabidopsis thaliana by performing Tandem Affinity Purification of proteins that interact with clathrin light chain, a principal component of the clathrin coat. Among the confirmed interactors, we found two putative homologues of the clathrin-coat uncoating factor auxilin previously described in non-plant systems. Overexpression of AUXILIN-LIKE1 and AUXILIN-LIKE2 in A. thaliana caused an arrest of seedling growth and development. This was concomitant with inhibited endocytosis due to blocking of clathrin recruitment after the initial step of adaptor protein binding to the plasma membrane. By contrast, auxilin-like(1/2) loss-of-function lines did not present endocytosis-related developmental or cellular phenotypes under normal growth conditions. This work contributes to the on-going characterization of the endocytotic machinery in plants and provides a robust tool for conditionally and specifically interfering with CME in A. thaliana. acknowledgement: We thank James Matthew Watson, Monika Borowska, and Peggy Stolt-Bergner at ProTech Facility of the Vienna Biocenter Core Facilities for the CRISPR/CAS9 construct; Anna Müller for assistance with molecular cloning; Sebastian Bednarek, Liwen Jiang, and Daniël Van Damme for sharing published material; Matyáš Fendrych, Daniël Van Damme, and Lindy Abas for valuable discussions; and Martine De Cock for help with correcting the manuscript.

The canalization hypothesis proposes that the auxin feedback on its polar flow is a crucial, plant-specific mechanism mediating multiple self-organizing developmental processes. Here, we used the auxin effect on the PIN polar localization in Arabidopsis thaliana roots as a proxy for the auxin feedback on the PIN polarity during canalization. We performed microarray experiments to find regulators of this process that act downstream of auxin. We identified genes that were transcriptionally regulated by auxin in an AXR3/IAA17- and ARF7/ARF19-dependent manner. Besides the known components of the PIN polarity, such as PID and PIP5K kinases, a number of potential new regulators were detected, among which the WRKY23 transcription factor, which was characterized in more detail. Gain- and loss-of-function mutants confirmed a role for WRKY23 in mediating the auxin effect on the PIN polarity. Accordingly, processes requiring auxin-mediated PIN polarity rearrangements, such as vascular tissue development during leaf venation, showed a higher WRKY23 expression and required the WRKY23 activity. Our results provide initial insights into the auxin transcriptional network acting upstream of PIN polarization and, potentially, canalization-mediated plant development. article_processing_charge: Yes author: - first_name: Tomas full_name: Prat, Tomas id: 3DA3BFEE-F248-11E8-B48F-1D18A9856A87 last_name: Prat - first_name: Jakub full_name: Hajny, Jakub id: 4800CC20-F248-11E8-B48F-1D18A9856A87 last_name: Hajny orcid: 0000-0003-2140-7195 - first_name: Wim full_name: Grunewald, Wim last_name: Grunewald - first_name: Mina K full_name: Vasileva, Mina K id: 3407EB18-F248-11E8-B48F-1D18A9856A87 last_name: Vasileva - first_name: Gergely full_name: Molnar, Gergely id: 34F1AF46-F248-11E8-B48F-1D18A9856A87 last_name: Molnar - first_name: Ricardo full_name: Tejos, Ricardo last_name: Tejos - first_name: Markus full_name: Schmid, Markus last_name: Schmid - first_name: Michael full_name: Sauer, Michael last_name: Sauer - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Prat T, Hajny J, Grunewald W, et al.

PIN polarity switches in response to different developmental and environmental signals have been shown to redirect auxin fluxes mediating certain developmental responses. PIN phosphorylation at different sites and by different kinases is crucial for PIN function. Here we investigate the role of PIN phosphorylation during gravitropic response. Loss- and gain-of-function mutants in PINOID and related kinases but not in D6PK kinase as well as mutations mimicking constitutive dephosphorylated or phosphorylated status of two clusters of predicted phosphorylation sites partially disrupted PIN3 phosphorylation and caused defects in gravitropic bending in roots and hypocotyls. In particular, they impacted PIN3 polarity rearrangements in response to gravity and during feed-back regulation by auxin itself. Thus PIN phosphorylation, besides regulating transport activity and apical-basal targeting, is also important for the rapid polarity switches in response to environmental and endogenous signals. article_number: '10279' article_processing_charge: No author: - first_name: Peter full_name: Grones, Peter id: 399876EC-F248-11E8-B48F-1D18A9856A87 last_name: Grones - first_name: Melinda F full_name: Abas, Melinda F id: 3CFB3B1C-F248-11E8-B48F-1D18A9856A87 last_name: Abas - first_name: Jakub full_name: Hajny, Jakub id: 4800CC20-F248-11E8-B48F-1D18A9856A87 last_name: Hajny orcid: 0000-0003-2140-7195 - first_name: Angharad full_name: Jones, Angharad last_name: Jones - first_name: Sascha full_name: Waidmann, Sascha last_name: Waidmann - first_name: Jürgen full_name: Kleine Vehn, Jürgen last_name: Kleine Vehn - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Grones P, Abas MF, Hajny J, et al.

We demonstrate that all known genes involved in auxin biosynthesis also have a role in root formation, from the initiation of a root meristem during embryogenesis to the generation of a functional root system with a primary root, secondary lateral root branches and adventitious roots. Furthermore, the versatile adaptation of root development in response to environmental challenges is mediated by both local and distant control of auxin biosynthesis. In conclusion, auxin homeostasis mediated by spatial and temporal regulation of auxin biosynthesis plays a central role in determining root architecture. article_number: '2587' article_processing_charge: No author: - first_name: Damilola full_name: Olatunji, Damilola last_name: Olatunji - first_name: Danny full_name: Geelen, Danny last_name: Geelen - first_name: Inge full_name: Verstraeten, Inge id: 362BF7FE-F248-11E8-B48F-1D18A9856A87 last_name: Verstraeten orcid: 0000-0001-7241-2328 citation: ama: Olatunji D, Geelen D, Verstraeten I.

The middle ground tissue layer comprises the majority of the plant body and serves a wide range of functions, including photosynthesis, selective nutrient uptake and storage, and gravity sensing. Ground tissue patterning and maintenance in Arabidopsis are controlled by a well-established gene network revolving around the key regulator SHORT-ROOT (SHR). In contrast, it is completely unknown how ground tissue identity is first specified from totipotent precursor cells in the embryo. The plant signaling molecule auxin, acting through AUXIN RESPONSE FACTOR (ARF) transcription factors, is critical for embryo patterning. The auxin effector ARF5/MONOPTEROS (MP) acts both cell-autonomously and noncell-autonomously to control embryonic vascular tissue formation and root initiation, respectively. Here we show that auxin response and ARF activity cell-autonomously control the asymmetric division of the first ground tissue cells. By identifying embryonic target genes, we show that MP transcriptionally initiates the ground tissue lineage and acts upstream of the regulatory network that controls ground tissue patterning and maintenance. Strikingly, whereas the SHR network depends on MP, this MP function is, at least in part, SHR independent. Our study therefore identifies auxin response as a regulator of ground tissue specification in the embryonic root, and reveals that ground tissue initiation and maintenance use different regulators and mechanisms. Moreover, our data provide a framework for the simultaneous formation of multiple cell types by the same transcriptional regulator. author: - first_name: Barbara full_name: Möller, Barbara last_name: Möller - first_name: Colette full_name: Ten Hove, Colette last_name: Ten Hove - first_name: Daoquan full_name: Xiang, Daoquan last_name: Xiang - first_name: Nerys full_name: Williams, Nerys last_name: Williams - first_name: Lorena full_name: López, Lorena last_name: López - first_name: Saiko full_name: Yoshida, Saiko id: 2E46069C-F248-11E8-B48F-1D18A9856A87 last_name: Yoshida - first_name: Margot full_name: Smit, Margot last_name: Smit - first_name: Raju full_name: Datla, Raju last_name: Datla - first_name: Dolf full_name: Weijers, Dolf last_name: Weijers citation: ama: Möller B, Ten Hove C, Xiang D, et al.

In land plants, several exocyst subunits are encoded by double or triple paralogs, culminating in tens of EXO70 paralogs. Out of 23 Arabidopsis thaliana EXO70 isoforms, we analyzed seven isoforms expressed in pollen. Genetic and microscopic analyses of single mutants in EXO70A2, EXO70C1, EXO70C2, EXO70F1, EXO70H3, EXO70H5, and EXO70H6 genes revealed that only a loss-of-function EXO70C2 allele resulted in a significant male-specific transmission defect (segregation 40%:51%:9%) due to aberrant pollen tube growth. Mutant pollen tubes grown in vitro exhibited an enhanced growth rate and a decreased thickness of the tip cell wall, causing tip bursts. However, exo70C2 pollen tubes could frequently recover and restart their speedy elongation, resulting in a repetitive stop-and-go growth dynamics. A pollenspecific depletion of the closest paralog, EXO70C1, using artificial microRNA in the exo70C2 mutant background, resulted in a complete pollen-specific transmission defect, suggesting redundant functions of EXO70C1 and EXO70C2. Both EXO70C1 and EXO70C2, GFP tagged and expressed under the control of their native promoters, localized in the cytoplasm of pollen grains, pollen tubes, and also root trichoblast cells. The expression of EXO70C2-GFP complemented the aberrant growth of exo70C2 pollen tubes. The absent EXO70C2 interactions with core exocyst subunits in the yeast two-hybrid assay, cytoplasmic localization, and genetic effect suggest an unconventional EXO70 function possibly as a regulator of exocytosis outside the exocyst complex. In conclusion, EXO70C2 is a novel factor contributing to the regulation of optimal tip growth of Arabidopsis pollen tubes.

The soil resources that plants require are often distributed in a highly heterogeneous pattern. To aid foraging, plants have evolved roots whose growth and development are highly responsive to soil signals. As a result, 3D root architecture is shaped by myriad environmental signals to ensure resource capture is optimised and unfavourable environments are avoided. The first signals sensed by newly germinating seeds — gravity and light — direct root growth into the soil to aid seedling establishment. Heterogeneous soil resources, such as water, nitrogen and phosphate, also act as signals that shape 3D root growth to optimise uptake. Root architecture is also modified through biotic interactions that include soil fungi and neighbouring plants. This developmental plasticity results in a ‘custom-made’ 3D root system that is best adapted to forage for resources in each soil environment that a plant colonises. author: - first_name: Emily full_name: Morris, Emily last_name: Morris - first_name: Marcus full_name: Griffiths, Marcus last_name: Griffiths - first_name: Agata full_name: Golebiowska, Agata last_name: Golebiowska - first_name: Stefan full_name: Mairhofer, Stefan last_name: Mairhofer - first_name: Jasmine full_name: Burr Hersey, Jasmine last_name: Burr Hersey - first_name: Tatsuaki full_name: Goh, Tatsuaki last_name: Goh - first_name: Daniel full_name: Von Wangenheim, Daniel id: 49E91952-F248-11E8-B48F-1D18A9856A87 last_name: Von Wangenheim orcid: 0000-0002-6862-1247 - first_name: Brian full_name: Atkinson, Brian last_name: Atkinson - first_name: Craig full_name: Sturrock, Craig last_name: Sturrock - first_name: Jonathan full_name: Lynch, Jonathan last_name: Lynch - first_name: Kris full_name: Vissenberg, Kris last_name: Vissenberg - first_name: Karl full_name: Ritz, Karl last_name: Ritz - first_name: Darren full_name: Wells, Darren last_name: Wells - first_name: Sacha full_name: Mooney, Sacha last_name: Mooney - first_name: Malcolm full_name: Bennett, Malcolm last_name: Bennett citation: ama: Morris E, Griffiths M, Golebiowska A, et al.

Substantial effort has been put into research on cellular trafficking of PIN proteins, which is thought to underlie their polar distribution. I participated in a forward genetic screen aimed at identifying novel regulators of PIN polarity. The screen yielded several genes which may be involved in PIN polarity regulation or participate in polar auxin transport by other means. Chapter 2 focuses on the endomembrane system, with particular attention to clathrin-mediated endocytosis. The project started with identification of several proteins that interact with clathrin light chains. Among them, I focused on two putative homologues of auxilin, which in non-plant systems is an endocytotic factor known for uncoating clathrin-coated vesicles in the final step of endocytosis. The body of my work consisted of an in-depth characterization of transgenic A. thaliana lines overexpressing these putative auxilins in an inducible manner. Overexpression of these proteins leads to an inhibition of endocytosis, as documented by imaging of cargoes and clathrin-related endocytic machinery. An extension of this work is an investigation into a concept of homeostatic regulation acting between distinct transport processes in the endomembrane system. With auxilin overexpressing lines, where endocytosis is blocked specifically, I made observations on the mutual relationship between two opposite trafficking processes of secretion and endocytosis. In Chapter 3, I analyze cortical microtubule arrays and their relationship to auxin signaling and polarized growth in elongating cells. In plants, microtubules are organized into arrays just below the plasma membrane, and it is thought that their function is to guide membrane-docked cellulose synthase complexes. These, in turn, influence cell wall structure and cell shape by directed deposition of cellulose fibres. In elongating cells, cortical microtubule arrays are able to reorient in relation to long cell axis, and these reorientations have been linked to cell growth and to signaling of growth-regulating factors such as auxin or light. In this chapter, I am addressing the causal relationship between microtubule array reorientation, growth, and auxin signaling. I arrive at a model where array reorientation is not guided by auxin directly, but instead is only controlled by growth, which, in turn, is regulated by auxin. alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Maciek full_name: Adamowski, Maciek id: 45F536D2-F248-11E8-B48F-1D18A9856A87 last_name: Adamowski orcid: 0000-0001-6463-5257 citation: ama: Adamowski M.

This regulation is achieved by different mechanisms, including auxin biosynthesis, metabolic conversions, degradation, and transport. Here, we introduce cis-cinnamic acid (c-CA) as a novel and unique addition to a small group of endogenous molecules affecting in planta auxin concentrations. c-CA is the photo-isomerization product of the phenylpropanoid pathway intermediate trans-CA (t-CA). When grown on c-CA-containing medium, an evolutionary diverse set of plant species were shown to exhibit phenotypes characteristic for high auxin levels, including inhibition of primary root growth, induction of root hairs, and promotion of adventitious and lateral rooting. By molecular docking and receptor binding assays, we showed that c-CA itself is neither an auxin nor an anti-auxin, and auxin profiling data revealed that c-CA does not significantly interfere with auxin biosynthesis. Single cell-based auxin accumulation assays showed that c-CA, and not t-CA, is a potent inhibitor of auxin efflux. Auxin signaling reporters detected changes in spatiotemporal distribution of the auxin response along the root of c-CA-treated plants, and long-distance auxin transport assays showed no inhibition of rootward auxin transport. Overall, these results suggest that the phenotypes of c-CA-treated plants are the consequence of a local change in auxin accumulation, induced by the inhibition of auxin efflux. This work reveals a novel mechanism how plants may regulate auxin levels and adds a novel, naturally occurring molecule to the chemical toolbox for the studies of auxin homeostasis. article_processing_charge: No article_type: original author: - first_name: Ward full_name: Steenackers, Ward last_name: Steenackers - first_name: Petr full_name: Klíma, Petr last_name: Klíma - first_name: Mussa full_name: Quareshy, Mussa last_name: Quareshy - first_name: Igor full_name: Cesarino, Igor last_name: Cesarino - first_name: Robert full_name: Kumpf, Robert last_name: Kumpf - first_name: Sander full_name: Corneillie, Sander last_name: Corneillie - first_name: Pedro full_name: Araújo, Pedro last_name: Araújo - first_name: Tom full_name: Viaene, Tom last_name: Viaene - first_name: Geert full_name: Goeminne, Geert last_name: Goeminne - first_name: Moritz full_name: Nowack, Moritz last_name: Nowack - first_name: Karin full_name: Ljung, Karin last_name: Ljung - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Joshua full_name: Blakeslee, Joshua last_name: Blakeslee - first_name: Ondřej full_name: Novák, Ondřej last_name: Novák - first_name: Eva full_name: Zažímalová, Eva last_name: Zažímalová - first_name: Richard full_name: Napier, Richard last_name: Napier - first_name: Wout full_name: Boerjan, Wout last_name: Boerjan - first_name: Bartel full_name: Vanholme, Bartel last_name: Vanholme citation: ama: Steenackers W, Klíma P, Quareshy M, et al.

Auxin transport between cells is mediated by a complex system of transporters such as AUX1/LAX, PIN, and ABCB proteins, and their localization and activity is thought to be influenced by phosphatases and kinases. Flavonols have been shown to alter auxin transport activity and changes in flavonol accumulation in the Arabidopsis thaliana rol1-2 mutant cause defects in auxin transport and seedling development. A new mutation in ROOTS CURL IN NPA 1 (RCN1), encoding a regulatory subunit of the phosphatase PP2A, was found to suppress the growth defects of rol1-2 without changing the flavonol content. rol1-2 rcn1-3 double mutants show wild type-like auxin transport activity while levels of free auxin are not affected by rcn1-3. In the rol1-2 mutant, PIN2 shows a flavonol-induced basal-to-apical shift in polar localization which is reversed in the rol1-2 rcn1-3 to basal localization. In vivo analysis of PINOID action, a kinase known to influence PIN protein localization in a PP2A-antagonistic manner, revealed a negative impact of flavonols on PINOID activity. Together, these data suggest that flavonols affect auxin transport by modifying the antagonistic kinase/phosphatase equilibrium. acknowledgement: European Research Council (project ERC-2011-StG-20101109-PSDP), European Social Fund (CZ.1.07/2.3.00/20.0043) and the Czech Science Foundation (GA13-40637S) [JF]. article_number: '41906' article_processing_charge: No author: - first_name: Benjamin full_name: Kuhn, Benjamin last_name: Kuhn - first_name: Tomasz full_name: Nodzyński, Tomasz last_name: Nodzyński - first_name: Sanae full_name: Errafi, Sanae last_name: Errafi - first_name: Rahel full_name: Bucher, Rahel last_name: Bucher - first_name: Shibu full_name: Gupta, Shibu last_name: Gupta - first_name: Bibek full_name: Aryal, Bibek last_name: Aryal - first_name: Petre full_name: Dobrev, Petre last_name: Dobrev - first_name: Laurent full_name: Bigler, Laurent last_name: Bigler - first_name: Markus full_name: Geisler, Markus last_name: Geisler - first_name: Eva full_name: Zažímalová, Eva last_name: Zažímalová - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Christoph full_name: Ringli, Christoph last_name: Ringli citation: ama: Kuhn B, Nodzyński T, Errafi S, et al.

Polarly localized auxin efflux proteins, including PIN-FORMED1 (PIN1), are dynamically transported between the endosomes and the plasma membrane (PM) in the plant cells. The intracellular trafficking of PIN1 protein is sensitive to a fungal toxin brefeldin A (BFA), which is known to inhibit guanine-nucleotide exchange factors for ADP ribosylation factors (ARF GEFs) such as GNOM. However, the molecular details of the BFA-sensitive trafficking pathway have not been revealed fully. In a previous study, we have identified an Arabidopsis mutant BFA-visualized endocytic trafficking defective 3 (ben3) which exhibited reduced sensitivity to BFA in terms of BFA-induced intracellular PIN1 agglomeration. Here, we show that BEN3 encodes a member of BIG family ARF GEFs, BIG2. Fluorescent proteins tagged BEN3/BIG2 co-localized with markers for TGN / early endosome (EE). Inspection of conditionally induced de novo synthesized PIN1 confirmed that its secretion to the PM is BFA-sensitive and established BEN3/BIG2 as a crucial component of this BFA action at the level of TGN/EE. Furthermore, ben3 mutation alleviated BFA-induced agglomeration of another TGN-localized ARF GEF BEN1/MIN7. Taken together our results suggest that BEN3/BIG2 is an ARF GEF component, which confers BFA sensitivity to the TGN/EE in Arabidopsis. article_number: 1801-1811 article_processing_charge: No author: - first_name: Saeko full_name: Kitakura, Saeko last_name: Kitakura - first_name: Maciek full_name: Adamowski, Maciek id: 45F536D2-F248-11E8-B48F-1D18A9856A87 last_name: Adamowski orcid: 0000-0001-6463-5257 - first_name: Yuki full_name: Matsuura, Yuki last_name: Matsuura - first_name: Luca full_name: Santuari, Luca last_name: Santuari - first_name: Hirotaka full_name: Kouno, Hirotaka last_name: Kouno - first_name: Kohei full_name: Arima, Kohei last_name: Arima - first_name: Christian full_name: Hardtke, Christian last_name: Hardtke - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Tatsuo full_name: Kakimoto, Tatsuo last_name: Kakimoto - first_name: Hirokazu full_name: Tanaka, Hirokazu last_name: Tanaka citation: ama: Kitakura S, Adamowski M, Matsuura Y, et al.

Thus far, studies on vascular patterning and regeneration have been conducted mainly in trees—woody plants—with a well-developed layer of vascular cambium and secondary tissues. Trees are difficult to use as genetic models, i.e., due to long generation time, unstable environmental conditions, and lack of available mutants and transgenic lines. Therefore, the use of the main genetic model plant Arabidopsis thaliana (L.) Heynh., with a wealth of available marker and transgenic lines, provides a unique opportunity to address molecular mechanism of vascular tissue formation and regeneration. With specific treatments, the tiny weed Arabidopsis can serve as a model to understand the growth of mighty trees and interconnect a tree physiology with molecular genetics and cell biology of Arabidopsis. alternative_title: - Agricultural and Biological Sciences author: - first_name: Ewa full_name: Mazur, Ewa last_name: Mazur - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: 'Mazur E, Friml J.

The Arabidopsis root is a widely used model for developmental, physiological and cell biological studies. Live imaging greatly aids these efforts, but the horizontal sample position and continuous root tip displacement present significant difficulties. Here, we develop a confocal microscope setup for vertical sample mounting and integrated directional illumination. We present TipTracker – a custom software for automatic tracking of diverse moving objects usable on various microscope setups. Combined, this enables observation of root tips growing along the natural gravity vector over prolonged periods of time, as well as the ability to induce rapid gravity or light stimulation. We also track migrating cells in the developing zebrafish embryo, demonstrating the utility of this system in the acquisition of high-resolution data sets of dynamic samples. We provide detailed descriptions of the tools enabling the easy implementation on other microscopes. acknowledged_ssus: - _id: M-Shop - _id: Bio acknowledgement: "Funding: Marie Curie Actions (FP7/2007-2013 no 291734) to Daniel von Wangenheim; Austrian Science Fund (M 2128-B21) to Matyáš Fendrych; Austrian Science Fund (FWF01_I1774S) to Eva Benková; European Research Council (FP7/2007-2013 no 282300) to Jiří Friml. \r\nThe authors are grateful to the Miba Machine Shop at IST Austria for their contribution to the microscope setup and to Yvonne Kemper for reading, understanding and correcting the manuscript.\r\n#BioimagingFacility" article_number: e26792 article_processing_charge: Yes author: - first_name: Daniel full_name: Von Wangenheim, Daniel id: 49E91952-F248-11E8-B48F-1D18A9856A87 last_name: Von Wangenheim orcid: 0000-0002-6862-1247 - first_name: Robert full_name: Hauschild, Robert id: 4E01D6B4-F248-11E8-B48F-1D18A9856A87 last_name: Hauschild orcid: 0000-0001-9843-3522 - first_name: Matyas full_name: Fendrych, Matyas id: 43905548-F248-11E8-B48F-1D18A9856A87 last_name: Fendrych orcid: 0000-0002-9767-8699 - first_name: Vanessa full_name: Barone, Vanessa id: 419EECCC-F248-11E8-B48F-1D18A9856A87 last_name: Barone orcid: 0000-0003-2676-3367 - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: von Wangenheim D, Hauschild R, Fendrych M, Barone V, Benková E, Friml J.

In plants, the mechanisms underlying the polar localization of cargo proteins are still largely unknown and appear to be fundamentally distinct from those operating in mammals. Here, we present a systematic, quantitative comparative analysis of the polar delivery and subcellular localization of proteins that characterize distinct polar plasma membrane domains in plant cells. The combination of microscopic analyses and computational modeling revealed a mechanistic framework common to diverse polar cargos and underlying the establishment and maintenance of apical, basal, and lateral polar domains in plant cells. This mechanism depends on the polar secretion, constitutive endocytic recycling, and restricted lateral diffusion of cargos within the plasma membrane. Moreover, our observations suggest that polar cargo distribution involves the individual protein potential to form clusters within the plasma membrane and interact with the extracellular matrix. Our observations provide insights into the shared cellular mechanisms of polar cargo delivery and polarity maintenance in plant cells. acknowledgement: "We thank Bonnie Bartel, Jenny Russinova and Niko Geldner\r\nfor sharing published material, Martine de Cock and Annick\r\nBleys for help in preparing the manuscript.

Regardless of the developmental importance of PINs, the structure of these transporters is poorly characterized. Here, we present experimental data concerning protein topology of plasma membrane-localized PINs. Utilizing approaches based on pH-dependent quenching of fluorescent reporters combined with immunolocalization techniques, we mapped the membrane topology of PINs and further cross-validated our results using available topology modeling software. We delineated the topology of PIN1 with two transmembrane (TM) bundles of five α-helices linked by a large intracellular loop and a C-terminus positioned outside the cytoplasm. Using constraints derived from our experimental data, we also provide an updated position of helical regions generating a verisimilitude model of PIN1. Since the canonical long PINs show a high degree of conservation in TM domains and auxin transport capacity has been demonstrated for Arabidopsis representatives of this group, this empirically enhanced topological model of PIN1 will be an important starting point for further studies on PIN structure–function relationships. In addition, we have established protocols that can be used to probe the topology of other plasma membrane proteins in plants. © 2016 The Authors acknowledgement: This research has been financially supported by the Ministry of Education, Youth and Sports of the Czech Republic under the project CEITEC 2020 (LQ1601) (T.N., M.Z., M.P., J.H.), Czech Science Foundation (13-40637S [J.F., M.Z.], 13-39982S [J.H.]); Research Foundation Flanders (Grant number FWO09/PDO/196) (S.V.) and the European Research Council (project ERC-2011-StG-20101109-PSDP) (J.F.).

Here we show apex decapitation activated competition for dominance in adjacent upper and lower axillary buds. A two-nodal-bud pea (Pisum sativum L.) was used as a model system to monitor and assess auxin flow, auxin transport channels, and dormancy and initiation status of axillary buds. Auxin flow was manipulated by lateral stem wounds or chemically by auxin efflux inhibitors 2,3,5-triiodobenzoic acid (TIBA), 1-N-naphtylphtalamic acid (NPA), or protein synthesis inhibitor cycloheximide (CHX) treatments, which served to interfere with axillary bud competition. Redirecting auxin flow to different points influenced which bud formed the outgrowing and dominant shoot. The obtained results proved that competition between upper and lower axillary buds as secondary auxin sources is based on the same auxin canalization principle that operates between the shoot apex and axillary bud. © The Author(s) 2016. acknowledgement: This research was carried out under the project CEITEC 2020 (LQ1601) with financial support from the Ministry of Education, Youth and Sports of the Czech Republic under the National Sustainability Programme II., supported by the project “CEITEC–Central European Institute of Technology” (CZ.1.05/1.1.00/02.0068) and the Agronomy faculty grant from Mendel University “IGA AF MENDELU” (IP 14/2013). article_number: '35955' author: - first_name: Jozef full_name: Balla, Jozef last_name: Balla - first_name: Zuzana full_name: Medved'Ová, Zuzana last_name: Medved'Ová - first_name: Petr full_name: Kalousek, Petr last_name: Kalousek - first_name: Natálie full_name: Matiješčuková, Natálie last_name: Matiješčuková - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Vilém full_name: Reinöhl, Vilém last_name: Reinöhl - first_name: Stanislav full_name: Procházka, Stanislav last_name: Procházka citation: ama: Balla J, Medved’Ová Z, Kalousek P, et al.

In plants, the hormone auxin regulates growth and development at every stage of a plant’s life cycle. Auxin signaling occurs through binding of the auxin molecule to a TIR1/AFB F-box ubiquitin ligase, allowing interaction with Aux/IAA transcriptional repressor proteins. These are subsequently ubiquitinated and degraded via the 26S proteasome, leading to derepression of auxin response factors (ARFs). How auxin is able to elicit such a diverse range of developmental responses through a single signaling module has not yet been resolved. Here we present an alternative auxin-sensing mechanism in which the ARF ARF3/ETTIN controls gene expression through interactions with process-specific transcription factors. This noncanonical hormonesensing mechanism exhibits strong preference for the naturally occurring auxin indole 3-acetic acid (IAA) and is important for coordinating growth and patterning in diverse developmental contexts such as gynoecium morphogenesis, lateral root emergence, ovule development, and primary branch formation. Disrupting this IAA-sensing ability induces morphological aberrations with consequences for plant fitness. Therefore, our findings introduce a novel transcription factor-based mechanism of hormone perception in plants. © 2016 Simonini et al. acknowledgement: "We thank Norwich Research Park Bioimaging, Grant Calder, Roy\r\nDunford, Caroline Smith, Paul Thomas, and Mark Youles for\r\ntechnical support; Charlie Scutt, Alejandro Ferrando, and George\r\nLomonossoff for plasmids; Toshiro Ito for seeds; Brendan Davies\r\nand Barry Causier for the REGIA library; and Mark Buttner,\r\nSimona Masiero, Fabio Rossi, Doris Wagner, and Jun Xiao for\r\nhelp and material.

Here, we combined in silico and in vivo approaches to identify a minimal mechanism producing auxin gradient-guided differential growth during the establishment of the apical hook in the model plant Arabidopsis thaliana. Computer simulation models based on experimental data demonstrate that asymmetric expression of the PIN-FORMED auxin efflux carrier at the concave (inner) versus convex (outer) side of the hook suffices to establish an auxin maximum in the epidermis at the concave side of the apical hook. Furthermore, we propose a mechanism that translates this maximum into differential growth, and thus curvature, of the apical hook. Through a combination of experimental and in silico computational approaches, we have identified the individual contributions of differential cell elongation and proliferation to defining the apical hook and reveal the role of auxin-ethylene crosstalk in balancing these two processes. © 2016 American Society of Plant Biologists.

Gravitropism involves gravity perception, signal transduction, and asymmetric growth response, with organ bending as a consequence [1]. Asymmetric growth results from the asymmetric distribution of the plant-specific signaling molecule auxin [2] that is generated by lateral transport, mediated in the hypocotyl predominantly by the auxin transporter PIN-FORMED3 (PIN3) [3–5]. Gravity stimulation polarizes PIN3 to the bottom sides of endodermal cells, correlating with increased auxin accumulation in adjacent tissues at the lower side of the stimulated organ, where auxin induces cell elongation and, hence, organ bending. A curvature response allows the hypocotyl to resume straight growth at a defined angle [6], implying that at some point auxin symmetry is restored to prevent overbending. Here, we present initial insights into cellular and molecular mechanisms that lead to the termination of the tropic response. We identified an auxin feedback on PIN3 polarization as underlying mechanism that restores symmetry of the PIN3-dependent auxin flow. Thus, two mechanistically distinct PIN3 polarization events redirect auxin fluxes at different time points of the gravity response: first, gravity-mediated redirection of PIN3-mediated auxin flow toward the lower hypocotyl side, where auxin gradually accumulates and promotes growth, and later PIN3 polarization to the opposite cell side, depleting this auxin maximum to end the bending. Accordingly, genetic or pharmacological interference with the late PIN3 polarization prevents termination of the response and leads to hypocotyl overbending. This observation reveals a role of auxin feedback on PIN polarity in the termination of the tropic response. © 2016 Elsevier Ltd' acknowledgement: "We thank Dr. Jie Li (Key Laboratory of Plant Molecular Physiology, Chinese Academy of Science, China) for the pPIN3::PIN3-GFP/DII::VENUS line and Martine De Cock for help in preparing the manuscript.

Since decades ago, it has been the prime receptor candidate for the plant hormone auxin with a plethora of described functions in auxin signaling and development. The developmental importance of ABP1 has recently been questioned by identification of Arabidopsis thaliana abp1 knock-out alleles that show no obvious phenotypes under normal growth conditions. In this study, we examined the contradiction between the normal growth and development of the abp1 knock-outs and the strong morphological defects observed in three different ethanol-inducible abp1 knock-down mutants ( abp1-AS, SS12K, SS12S). By analyzing segregating populations of abp1 knock-out vs. abp1 knock-down crosses we show that the strong morphological defects that were believed to be the result of conditional down-regulation of ABP1 can be reproduced also in the absence of the functional ABP1 protein. This data suggests that the phenotypes in abp1 knock-down lines are due to the off-target effects and asks for further reflections on the biological function of ABP1 or alternative explanations for the missing phenotypic defects in the abp1 loss-of-function alleles. acknowledgement: "This work was supported by ERC Independent Research grant (ERC-2011-StG-20101109-PSDP to JF).

In this way trajectories of individual endosomes can be mapped and linked to physiological processes as cell growth. However, other aspects of dynamic behavior including endosomal interactions are difficult to follow in this manner. Therefore, we characterized the localization and dynamic properties of early and late endosomes throughout the entire course of root hair formation by means of spinning disc time lapse imaging and post-acquisition automated multitracking and quantitative analysis. Our results show differential motile behavior of early and late endosomes and interactions of late endosomes that may be specified to particular root hair domains. Detailed data analysis revealed a particular transient interaction between late endosomes—termed herein as dancing-endosomes—which is not concluding to vesicular fusion. Endosomes preferentially located in the root hair tip interacted as dancing-endosomes and traveled short distances during this interaction. Finally, sizes of early and late endosomes were addressed by means of super-resolution structured illumination microscopy (SIM) to corroborate measurements on the spinning disc. This is a first study providing quantitative microscopic data on dynamic spatio-temporal interactions of endosomes during root hair tip growth. acknowledgement: "This work was supported by National Program for Sustainability I (grant no.

The RON3 gene was map-based cloned starting from the ron3-1 leaf mutant and found to be a unique, plant-specific gene coding for a protein with high and dispersed proline content. The ron3-1 and ron3-2 mutant phenotypes [i.e., reduced apical dominance, primary root length, lateral root emergence, and growth; increased ectopic stages II, IV, and V lateral root primordia; decreased auxin maxima in indole-3-acetic acid (IAA)-treated root apical meristems; hypergravitropic root growth and response; increased IAA levels in shoot apices; and reduced auxin accumulation in root meristems] support a role for RON3 in auxin biology. The affinity-purified PP2A complex with RON3 as bait suggested that RON3 might act in PIN transporter trafficking. Indeed, pharmacological interference with vesicle trafficking processes revealed that single ron3-2 and double ron3-2 rcn1 mutants have altered PIN polarity and endocytosis in specific cells. Our data indicate that RON3 contributes to auxin-mediated development by playing a role in PIN recycling and polarity establishment through regulation of the PP2A complex activity. acknowledgement: "This work was supported by the Ghent University Special Research Fund (M.K.), the European Research Council (Project ERC-2011-StG-20101109-PSDP) (to J.F.), and the Körber European Science Foun-\r\ndation (J.F.).

Polarity and flexibility of this process is provided by constant cycling of auxin transporter vesicles along actin filaments, coordinated by a positive auxinactin feedback loop. Both polar auxin transport and vesicle cycling are inhibited by synthetic auxin transport inhibitors, such as 1-Nnaphthylphthalamic acid (NPA), counteracting the effect of auxin; however, underlying targets and mechanisms are unclear. Using NMR, we map the NPA binding surface on the Arabidopsis thaliana ABCB chaperone TWISTED DWARF1 (TWD1).We identify ACTIN7 as a relevant, although likely indirect, TWD1 interactor, and show TWD1-dependent regulation of actin filament organization and dynamics and that TWD1 is required for NPA-mediated actin cytoskeleton remodeling. The TWD1-ACTIN7 axis controls plasma membrane presence of efflux transporters, and as a consequence act7 and twd1 share developmental and physiological phenotypes indicative of defects in auxin transport. These can be phenocopied by NPA treatment or by chemical actin (de)stabilization. We provide evidence that TWD1 determines downstreamlocations of auxin efflux transporters by adjusting actin filament debundling and dynamizing processes and mediating NPA action on the latter. This function appears to be evolutionary conserved since TWD1 expression in budding yeast alters actin polarization and cell polarity and provides NPA sensitivity. acknowledgement: ' This work was supported by grants from the European Social Fund (CZ.1.07/2.3.00/20.0043), the Czech Science Foundation GAČR (GA13-40637S) to J.F. and M.Z., the Ministry of Education, Youth, and Sports of the Czech Republic under the project CEITEC 2020 (LQ1601) to M.Z., the Ministry for Higher Education and Research of Luxembourg (REC-LOCM-20140703) to C.T., the Partial Funding Program for Short Stays Abroad of CONICET Argentina (to N.I.B.), Swiss National Funds, the Pool de Recherche of the University of Fribourg, and the Novartis Foundation (all to M.G.).

Here, we investigated putative sorting signals in the large cytosolic loop of the Arabidopsis (Arabidopsis thaliana) PIN-FORMED1 (PIN1) auxin transporter, which are involved in binding μ-adaptins and thus in PIN1 trafficking and localization. We found that Phe-165 and Tyr-280, Tyr-328, and Tyr-394 are involved in the binding of different μ-adaptins in vitro. However, only Phe-165, which binds μA(μ2)- and μD(μ3)-adaptin, was found to be essential for PIN1 trafficking and localization in vivo. The PIN1:GFP-F165A mutant showed reduced endocytosis but also localized to intracellular structures containing several layers of membranes and endoplasmic reticulum (ER) markers, suggesting that they correspond to ER or ER-derived membranes. While PIN1:GFP localized normally in a μA (μ2)-adaptin mutant, it accumulated in big intracellular structures containing LysoTracker in a μD (μ3)-adaptin mutant, consistent with previous results obtained with mutants of other subunits of the AP-3 complex. Our data suggest that Phe-165, through the binding of μA (μ2)- and μD (μ3)-adaptin, is important for PIN1 endocytosis and for PIN1 trafficking along the secretory pathway, respectively. acknowledgement: "We thank Dr. R.

Although the PEPR-mediated signaling components and responses have been studied extensively, the contributions of the subcellular localization and dynamics of the active PEPRs remain largely unknown. We used live-cell imaging of the fluorescently labeled and bioactive pep1 to visualize the intracellular behavior of the PEPRs in the Arabidopsis root meristem. We found that AtPep1 decorated the plasma membrane (PM) in a receptor-dependent manner and cointernalized with PEPRs. Trafficking of the AtPep1-PEPR1 complexes to the vacuole required neither the trans-Golgi network/early endosome (TGN/EE)-localized vacuolar H+ -ATPase activity nor the function of the brefeldin A-sensitive ADP-ribosylation factor-guanine exchange factors (ARF-GEFs). In addition, AtPep1 and different TGN/EE markers colocalized only rarely, implying that the intracellular route of this receptor-ligand pair is largely independent of the TGN/EE. Inducible overexpression of the Arabidopsis clathrin coat disassembly factor, Auxilin2, which inhibits clathrin-mediated endocytosis (CME), impaired the AtPep1-PEPR1 internalization and compromised AtPep1-mediated responses. Our results show that clathrin function at the PM is required to induce plant defense responses, likely through CME of cell surface-located signaling components.\r\n" acknowledgement: "F.A.O.-M. was supported by special\r\nresearch funding from the Flemish Government for a joint doctorate fellowship\r\nat Ghent University, and funding from the Student Program\r\n–\r\nGraduate Studies\r\nPlan Program from the Coordination for the Improvement of Higher Educa-\r\ntion Personnel, Brazil, for a doctorate fellowship at the University of São Paulo.\r\nX.Z. and Q.L. are indebted to the China Science Council and G.P.d.O. to the\r\n“\r\nCiência sem Fronteiras\r\n”\r\nfor predoctoral fellowships.

The hormone auxin is redistributed in stimulated organs leading to differential growth and bending. Auxin application triggers rapid cell wall acidification and elongation of aerial organs of plants, but the molecular players mediating these effects are still controversial. Here we use genetically-encoded pH and auxin signaling sensors, pharmacological and genetic manipulations available for Arabidopsis etiolated hypocotyls to clarify how auxin is perceived and the downstream growth executed. We show that auxin-induced acidification occurs by local activation of H+-ATPases, which in the context of gravity response is restricted to the lower organ side. This auxin-stimulated acidification and growth require TIR1/AFB-Aux/IAA nuclear auxin perception. In addition, auxin-induced gene transcription and specifically SAUR proteins are crucial downstream mediators of this growth. Our study provides strong experimental support for the acid growth theory and clarified the contribution of the upstream auxin perception mechanisms. acknowledgement: "The authors express their gratitude to Veronika Bierbaum, Robert Hauschild for help with MATLAB,\r\nDaniel von Wangenheim for the gravitropism assay.

Cytokinins have also been proposed to play a role in controlling root gravitropism, but conclusive evidence is lacking. We present a detailed study of the dynamics of root bending early after gravistimulation, which revealed a delayed gravitropic response in transgenic lines with depleted endogenous cytokinins (Pro35S:AtCKX) and cytokinin signaling mutants. Pro35S:AtCKX lines, as well as a cytokinin receptor mutant ahk3, showed aberrations in the auxin response distribution in columella cells consistent with defects in the auxin transport machinery. Using in vivo real-time imaging of PIN3-GFP and PIN7-GFP in AtCKX3 overexpression and ahk3 backgrounds, we observed wild-type-like relocalization of PIN proteins in the columella early after gravistimulation, with gravity-induced relocalization of PIN7 faster than that of PIN3. Nonetheless, the cellular distribution of PIN3 and PIN7 and expression of PIN7 and the auxin influx carrier AUX1 was affected in AtCKX overexpression lines. Based on the retained cytokinin sensitivity in pin3 pin4 pin7 mutant, we propose the AUX1-mediated auxin transport rather than columella-located PIN proteins as a target of endogenous cytokinins in the control of root gravitropism. acknowledgement: 'Funded by Ministry of Education, Youth and Sports Czech Republic.

A series of complex structural changes follows, generating mature pollen grains capable of performing the double fertilization of the female megasporophyte. Several signaling molecules, including hormones and lipids, have been involved in the regulation and appropriate control of pollen development. Phosphatidylinositol 4-phophate 5-kinases (PIP5K), which catalyze the biosynthesis of the phosphoinositide PtdIns(4,5)P2, are important for tip polar growth of root hairs and pollen tubes, embryo development, vegetative plant growth, and responses to the environment. Here, we report a role of PIP5Ks during microgametogenesis. PIP5K1 and PIP5K2 are expressed during early stages of pollen development and their transcriptional activity respond to auxin in pollen grains. Early male gametophytic lethality to certain grade was observed in both pip5k1-/- and pip5k2-/- single mutants. The number of pip5k mutant alleles is directly related to the frequency of aborted pollen grains suggesting the two genes are involved in the same function. Indeed PIP5K1 and PIP5K2 are functionally redundant since homozygous double mutants did not render viable pollen grains. The loss of function of PIP5K1 and PIP5K2results in defects in vacuole morphology in pollen at the later stages and epidermal root cells. Our results show that PIP5K1, PIP5K2 and phosphoinositide signaling are important cues for early developmental stages and vacuole formation during microgametogenesis. acknowledgement: the Odysseus Program of the Research Foundation-Flanders [G091608] to JF. author: - first_name: José full_name: Ugalde, José last_name: Ugalde - first_name: Cecilia full_name: Rodríguez Furlán, Cecilia last_name: Rodríguez Furlán - first_name: Riet full_name: De Rycke, Riet last_name: De Rycke - first_name: Lorena full_name: Norambuena, Lorena last_name: Norambuena - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Gabriel full_name: León, Gabriel last_name: León - first_name: Ricardo full_name: Tejos, Ricardo last_name: Tejos citation: ama: Ugalde J, Rodríguez Furlán C, De Rycke R, et al.

Among the eight members of the Arabidopsis PIN family, PIN6 is the least characterized candidate. In this study we generated functional, fluorescent protein-tagged PIN6 proteins and performed comprehensive analysis of their subcellular localization and also performed a detailed functional characterization of PIN6 and its developmental roles. The localization study of PIN6 revealed a dual localization at the plasma membrane (PM) and endoplasmic reticulum (ER). Transport and metabolic profiling assays in cultured cells and Arabidopsis strongly suggest that PIN6 mediates both auxin transport across the PM and intracellular auxin homeostasis, including the regulation of free auxin and auxin conjugates levels. As evidenced by the loss- and gain-of-function analysis, the complex function of PIN6 in auxin transport and homeostasis is required for auxin distribution during lateral and adventitious root organogenesis and for progression of these developmental processes. These results illustrate a unique position of PIN6 within the family of PIN auxin transporters and further add complexity to the developmentally crucial process of auxin transport. acknowledgement: This work was supported by the European Research Council (project ERC-2011-StG-20101109-PSDP, project CEITEC (CZ.1.05/1.1.00/02.0068) and the Czech Science Foundation GACR (project no. 13-4063 7S to J.F.) author: - first_name: Sibu full_name: Simon, Sibu id: 4542EF9A-F248-11E8-B48F-1D18A9856A87 last_name: Simon orcid: 0000-0002-1998-6741 - first_name: Petr full_name: Skůpa, Petr last_name: Skůpa - first_name: Tom full_name: Viaene, Tom last_name: Viaene - first_name: Marta full_name: Zwiewka, Marta last_name: Zwiewka - first_name: Ricardo full_name: Tejos, Ricardo last_name: Tejos - first_name: Petr full_name: Klíma, Petr last_name: Klíma - first_name: Mária full_name: Čarná, Mária last_name: Čarná - first_name: Jakub full_name: Rolčík, Jakub last_name: Rolčík - first_name: Riet full_name: De Rycke, Riet last_name: De Rycke - first_name: Ignacio full_name: Moreno, Ignacio last_name: Moreno - first_name: Petre full_name: Dobrev, Petre last_name: Dobrev - first_name: Ariel full_name: Orellana, Ariel last_name: Orellana - first_name: Eva full_name: Zažímalová, Eva last_name: Zažímalová - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Simon S, Skůpa P, Viaene T, et al.

The shoot apical meristem (SAM) provides a stable environment for the maintenance of stem cells. All cells inside the SAM divide, yet boundaries and patterns are maintained. Experimental evidence indicates that patterning is independent of cell lineage, thus a dynamic self-regulatory mechanism is required. A pivotal role in the organization of the SAM is played by the WUSCHEL gene (WUS). An important question in this regard is that how WUS expression is positioned in the SAM via a cell-lineage independent signaling mechanism. In this study we demonstrate via mathematical modeling that a combination of an inhibitor of the Cytokinin (CK) receptor, Arabidopsis histidine kinase 4 (AHK4) and two morphogens originating from the top cell layer, can plausibly account for the cell lineage-independent centering of WUS expression within SAM. Furthermore, our laser ablation and microsurgical experiments support the hypothesis that patterning in SAM occurs at the level of CK reception and signaling. The model suggests that the interplay between CK signaling, WUS/CLV feedback loop and boundary signals can account for positioning of the WUS expression, and provides directions for further experimental investigation. acknowledgement: We thank J. Traas, B. Müller and V. Reddy for providing seed materials and Y. Deb for advice regarding the laser ablation experiments.

Auxin is directionally transported from cell to cell by the action of specific auxin influx [AUXIN-RESISTANT1 (AUX1)] and efflux [PIN-FORMED (PIN)] transport regulators, whose polar, subcellular localizations are aligned with the direction of the auxin flow. Auxin itself regulates its own transport by modulation of the expression and subcellular localization of the auxin transporters. Increased auxin levels promote the transcription of PIN2 and AUX1 genes as well as stabilize PIN proteins at the plasma membrane, whereas prolonged auxin exposure increases the turnover of PIN proteins and their degradation in the vacuole. In this study, we applied a forward genetic approach, to identify molecular components playing a role in the auxin-mediated degradation. We generated EMS-mutagenized Arabidopsis PIN2::PIN2:GFP, AUX1::AUX1:YFP eir1aux1 populations and designed a screen for mutants with persistently strong fluorescent signals of the tagged PIN2 and AUX1 after prolonged treatment with the synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D). This approach yielded novel auxin degradation mutants defective in trafficking and degradation of PIN2 and AUX1 proteins and established a role for auxin-mediated degradation in plant development. acknowledgement: 'European Social Fund (CZ.1.07/2.3.00/20.0043) and the Czech Science Foundation GAČR (GA13-40637S) to JF.

Mitochondrial uncouplers dissipate this proton gradient and disrupt numerous cellular processes, including vesicular trafficking, mainly through energy depletion. Here we show that Endosidin9 (ES9), a novel mitochondrial uncoupler, is a potent inhibitor of clathrin-mediated endocytosis (CME) in different systems and that ES9 induces inhibition of CME not because of its effect on cellular ATP, but rather due to its protonophore activity that leads to cytoplasm acidification. We show that the known tyrosine kinase inhibitor tyrphostinA23, which is routinely used to block CME, displays similar properties, thus questioning its use as a specific inhibitor of cargo recognition by the AP-2 adaptor complex via tyrosine motif-based endocytosis signals. Furthermore, we show that cytoplasm acidification dramatically affects the dynamics and recruitment of clathrin and associated adaptors, and leads to reduction of phosphatidylinositol 4,5-biphosphate from the plasma membrane. acknowledgement: "We thank Yvon Jaillais, Ikuko Hara-Nishimura, Akihiko Nakano, Takashi Ueda and Jinxing Lin for providing materials, Natasha Raikhel, Glenn Hicks, Steffen Vanneste, and Ricardo Tejos for useful suggestions, Patrick Callaerts for providing S2 Drosophila cell cultures, Michael Sixt for providing HeLa cells, Annick Bleys for literature searches, VIB Bio Imaging Core for help with imaging conditions and Martine De Cock for help in preparing the article.

Particularly, the characterization of the CLE41-PXY/TDR signaling pathway has greatly advanced our understanding on the potential roles of CLE peptides in vascular development and wood formation. Nevertheless, our knowledge on this gene family in a tree species is limited. In a recent study, we reported on a systematically investigation of the CLE gene family in Populus trichocarpa . The potential roles of PtCLE genes were studied by comparative analysis and transcriptional pro fi ling. Among fi fty PtCLE members, many PtCLE proteins share identical CLE motifs or contain the same CLE motif as that of AtCLEs, while PtCLE genes exhibited either comparable or distinct expression patterns comparing to their Arabidopsis counterparts. These fi ndings indicate the existence of both functional conservation and functional divergence between PtCLEs and their AtCLE orthologues. Our results provide valuable resources for future functional investigations of these critical signaling molecules in woody plants.

According to the canalization hypothesis, the plant hormone auxin serves as polarizing signal that mediates directional channel formation underlying the spatio-temporal vasculature patterning. A necessary part of canalization is a positive feedback between auxin signaling and polarity of the intercellular auxin flow. The cellular and molecular mechanisms of this process are still poorly understood, not the least, because of a lack of a suitable model system. We show that the main genetic model plant, Arabidopsis (Arabidopsis thaliana) can be used to study the canalization during vascular cambium regeneration and new vasculature formation. We monitored localized auxin responses, directional auxin-transport channels formation, and establishment of new vascular cambium polarity during regenerative processes after stem wounding. The increased auxin response above and around the wound preceded the formation of PIN1 auxin transporter-marked channels from the primarily homogenous tissue and the transient, gradual changes in PIN1 localization preceded the polarity of newly formed vascular tissue. Thus, Arabidopsis is a useful model for studies of coordinated tissue polarization and vasculature formation after wounding allowing for genetic and mechanistic dissection of the canalization hypothesis. acknowledgement: We wish to thank Prof. Ewa U.

This dual V-ATPase function has impeded our understanding of how the pH homeostasis within the plant TGN/EE controls exo- and endocytosis. Here, we show that the weak V-ATPase mutant deetiolated3 (det3) displayed a pH increase in the TGN/EE, but not in the vacuole, strongly impairing secretion and recycling of the brassinosteroid receptor and the cellulose synthase complexes to the plasma membrane, in contrast to mutants lacking tonoplast-localized V-ATPase activity only. The brassinosteroid insensitivity and the cellulose deficiency defects in det3 were tightly correlated with reduced Golgi and TGN/EE motility. Thus, our results provide strong evidence that acidification of the TGN/EE, but not of the vacuole, is indispensable for functional secretion and recycling in plants. article_number: '15094' article_processing_charge: No article_type: original author: - first_name: Luo full_name: Yu, Luo last_name: Yu - first_name: Stefan full_name: Scholl, Stefan last_name: Scholl - first_name: Anett full_name: Doering, Anett last_name: Doering - first_name: Zhang full_name: Yi, Zhang last_name: Yi - first_name: Niloufer full_name: Irani, Niloufer last_name: Irani - first_name: Simone full_name: Di Rubbo, Simone last_name: Di Rubbo - first_name: Lutz full_name: Neumetzler, Lutz last_name: Neumetzler - first_name: Praveen full_name: Krishnamoorthy, Praveen last_name: Krishnamoorthy - first_name: Isabelle full_name: Van Houtte, Isabelle last_name: Van Houtte - first_name: Evelien full_name: Mylle, Evelien last_name: Mylle - first_name: Volker full_name: Bischoff, Volker last_name: Bischoff - first_name: Samantha full_name: Vernhettes, Samantha last_name: Vernhettes - first_name: Johan full_name: Winne, Johan last_name: Winne - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: York full_name: Stierhof, York last_name: Stierhof - first_name: Karin full_name: Schumacher, Karin last_name: Schumacher - first_name: Staffan full_name: Persson, Staffan last_name: Persson - first_name: Eugenia full_name: Russinova, Eugenia last_name: Russinova citation: ama: Yu L, Scholl S, Doering A, et al.

Ammonium stress rapidly leads to various metabolic and hormonal imbalances that ultimately inhibit root and shoot growth in many plant species, including Arabidopsis thaliana (L.) Heynh. To identify molecular and genetic factors involved in seedling survival with prolonged exclusive NH4+ nutrition, a transcriptomic analysis with microarrays was used. Substantial transcriptional differences were most pronounced in (NH4)2SO4-grown seedlings, compared with plants grown on KNO3 or NH4NO3. Consistent with previous physiological analyses, major differences in the expression modules of photosynthesis-related genes, an altered mitochondrial metabolism, differential expression of the primary NH4+ assimilation, alteration of transporter gene expression and crucial changes in cell wall biosynthesis were found. A major difference in plant hormone responses, particularly of auxin but not cytokinin, was striking. The activity of the DR5::GUS reporter revealed a dramatically decreased auxin response in (NH4)2SO4-grown primary roots. The impaired root growth on (NH4)2SO4 was partially rescued by exogenous auxin or in specific mutants in the auxin pathway. The data suggest that NH4+-induced nutritional and metabolic imbalances can be partially overcome by elevated auxin levels. article_processing_charge: No article_type: original author: - first_name: Huaiyu full_name: Yang, Huaiyu last_name: Yang - first_name: Jenny full_name: Von Der Fecht Bartenbach, Jenny last_name: Von Der Fecht Bartenbach - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Jan full_name: Lohmann, Jan last_name: Lohmann - first_name: Benjamin full_name: Neuhäuser, Benjamin last_name: Neuhäuser - first_name: Uwe full_name: Ludewig, Uwe last_name: Ludewig citation: ama: Yang H, Von Der Fecht Bartenbach J, Friml J, Lohmann J, Neuhäuser B, Ludewig U.

The Arabidopsis R2R3-MYB transcription factor FOUR LIPS (FLP) and its paralogue MYB88 regulate terminal divisions during stomatal development, as well as female reproductive development and stress responses. Here we show that FLP and MYB88 act redundantly but differentially in regulating the transcription of PIN3 and PIN7 in gravity-sensing cells of primary and lateral roots. On the one hand, FLP is involved in responses to gravity stimulation in primary roots, whereas on the other, FLP and MYB88 function complementarily in establishing the gravitropic set-point angles of lateral roots. Our results support a model in which FLP and MYB88 expression specifically determines the temporal-spatial patterns of PIN3 and PIN7 transcription that are closely associated with their preferential functions during root responses to gravity. article_number: '8822' author: - first_name: Hongzhe full_name: Wang, Hongzhe last_name: Wang - first_name: Kezhen full_name: Yang, Kezhen last_name: Yang - first_name: Junjie full_name: Zou, Junjie last_name: Zou - first_name: Lingling full_name: Zhu, Lingling last_name: Zhu - first_name: Zidian full_name: Xie, Zidian last_name: Xie - first_name: Miyoterao full_name: Morita, Miyoterao last_name: Morita - first_name: Masao full_name: Tasaka, Masao last_name: Tasaka - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Erich full_name: Grotewold, Erich last_name: Grotewold - first_name: Tom full_name: Beeckman, Tom last_name: Beeckman - first_name: Steffen full_name: Vanneste, Steffen last_name: Vanneste - first_name: Fred full_name: Sack, Fred last_name: Sack - first_name: Jie full_name: Le, Jie last_name: Le citation: ama: Wang H, Yang K, Zou J, et al.

Furthermore, strigolactones are involved in the regulation of lateral and adventitious root development, root cell division [5, 6], secondary growth [7], and leaf senescence [8]. Recently, we discovered the strigolactone transporter Petunia axillaris PLEIOTROPIC DRUG RESISTANCE 1 (PaPDR1), which is required for efficient mycorrhizal colonization and inhibition of lateral bud outgrowth [9]. However, how strigolactones are transported through the plant remained unknown. Here we show that PaPDR1 exhibits a cell-type-specific asymmetric localization in different root tissues. In root tips, PaPDR1 is co-expressed with the strigolactone biosynthetic gene DAD1 (CCD8), and it is localized at the apical membrane of root hypodermal cells, presumably mediating the shootward transport of strigolactone. Above the root tip, in the hypodermal passage cells that form gates for the entry of mycorrhizal fungi, PaPDR1 is present in the outer-lateral membrane, compatible with its postulated function as strigolactone exporter from root to soil. Transport studies are in line with our localization studies since (1) a papdr1 mutant displays impaired transport of strigolactones out of the root tip to the shoot as well as into the rhizosphere and (2) DAD1 expression and PIN1/PIN2 levels change in plants deregulated for PDR1 expression, suggestive of variations in endogenous strigolactone contents. In conclusion, our results indicate that the polar localizations of PaPDR1 mediate directional shootward strigolactone transport as well as localized exudation into the soil. acknowledgement: "This work was funded by a grant of the Swiss National Foundation to E.M.\r\nWe thank Dr. José María Mateos (University of Zurich) for providing us with the vibratome, Prof. Dolf Weijers (Wageningen University, the Netherlands) for shipping us his set of ligation-independent cloning vectors, Prof. Bruno Humbel (University of Lausanne) for suggestions on GFP-PDR1 detection, and Dr. Undine Krügel (University of Zurich) and Prof. Michal Jasinski (Polish Academy of Science) for hints on protein quantification." author: - first_name: Joëlle full_name: Sasse, Joëlle last_name: Sasse - first_name: Sibu full_name: Simon, Sibu id: 4542EF9A-F248-11E8-B48F-1D18A9856A87 last_name: Simon orcid: 0000-0002-1998-6741 - first_name: Christian full_name: Gübeli, Christian last_name: Gübeli - first_name: Guowei full_name: Liu, Guowei last_name: Liu - first_name: Xi full_name: Cheng, Xi last_name: Cheng - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Harro full_name: Bouwmeester, Harro last_name: Bouwmeester - first_name: Enrico full_name: Martinoia, Enrico last_name: Martinoia - first_name: Lorenzo full_name: Borghi, Lorenzo last_name: Borghi citation: ama: Sasse J, Simon S, Gübeli C, et al.

In animals and plants, different forms of PCD play crucial roles in development, immunity, and responses to the environment. While the molecular control of some animal PCD forms such as apoptosis is known in great detail, we still know comparatively little about the regulation of the diverse types of plant PCD. In part, this deficiency in molecular understanding is caused by the lack of reliable reporters to detect PCD processes. Here, we addressed this issue by using a combination of bioinformatics approaches to identify commonly regulated genes during diverse plant PCD processes in Arabidopsis (Arabidopsis thaliana). Our results indicate that the transcriptional signatures of developmentally controlled cell death are largely distinct from the ones associated with environmentally induced cell death. Moreover, different cases of developmental PCD share a set of cell death-associated genes. Most of these genes are evolutionary conserved within the green plant lineage, arguing for an evolutionary conserved core machinery of developmental PCD. Based on this information, we established an array of specific promoter-reporter lines for developmental PCD in Arabidopsis. These PCD indicators represent a powerful resource that can be used in addition to established morphological and biochemical methods to detect and analyze PCD processes in vivo and in planta. author: - first_name: Yadira full_name: Olvera Carrillo, Yadira last_name: Olvera Carrillo - first_name: Michiel full_name: Van Bel, Michiel last_name: Van Bel - first_name: Tom full_name: Van Hautegem, Tom last_name: Van Hautegem - first_name: Matyas full_name: Fendrych, Matyas id: 43905548-F248-11E8-B48F-1D18A9856A87 last_name: Fendrych orcid: 0000-0002-9767-8699 - first_name: Marlies full_name: Huysmans, Marlies last_name: Huysmans - first_name: Mária full_name: Šimášková, Mária last_name: Šimášková - first_name: Matthias full_name: Van Durme, Matthias last_name: Van Durme - first_name: Pierre full_name: Buscaill, Pierre last_name: Buscaill - first_name: Susana full_name: Rivas, Susana last_name: Rivas - first_name: Núria full_name: Coll, Núria last_name: Coll - first_name: Frederik full_name: Coppens, Frederik last_name: Coppens - first_name: Steven full_name: Maere, Steven last_name: Maere - first_name: Moritz full_name: Nowack, Moritz last_name: Nowack citation: ama: Olvera Carrillo Y, Van Bel M, Van Hautegem T, et al.

Here, its role in root development was explored. Compared to the wild type, the elp2 mutant exhibited an accelerated differentiation of its root stem cells and cell division was more active in its quiescent centre (QC). The key transcription factors responsible for maintaining root stem cell and QC identity, such as AP2 transcription factors PLT1 (PLETHORA1) and PLT2 (PLETHORA2), GRAS transcription factors such as SCR (SCARECROW) and SHR (SHORT ROOT) and WUSCHEL-RELATED HOMEOBOX5 transcription factor WOX5, were all strongly down-regulated in the mutant. On the other hand, expression of the G2/M transition activator CYCB1 was substantially induced in elp2. The auxin efflux transporters PIN1 and PIN2 showed decreased protein levels and PIN1 also displayed mild polarity alterations in elp2, which resulted in a reduced auxin content in the root tip. Either the acetylation or methylation level of each of these genes differed between the mutant and the wild type, suggesting that the ELP2 regulation of root development involves the epigenetic modification of a range of transcription factors and other developmental regulators. author: - first_name: Yuebin full_name: Jia, Yuebin last_name: Jia - first_name: Huiyu full_name: Tian, Huiyu last_name: Tian - first_name: Hongjiang full_name: Li, Hongjiang id: 33CA54A6-F248-11E8-B48F-1D18A9856A87 last_name: Li orcid: 0000-0001-5039-9660 - first_name: Qianqian full_name: Yu, Qianqian last_name: Yu - first_name: Lei full_name: Wang, Lei last_name: Wang - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Zhaojun full_name: Ding, Zhaojun last_name: Ding citation: ama: Jia Y, Tian H, Li H, et al.

Despite significant effort, evidence of developmental functions of cyclophilin A in non-plant systems has remained obscure. Mutations in a tomato (Solanum lycopersicum) cyclophilin A ortholog, DIAGEOTROPICA (DGT), have been shown to abolish the organogenesis of lateral roots; however, a mechanistic explanation of the phenotype is lacking. Here, we show that the dgt mutant lacks auxin maxima relevant to priming and specification of lateral root founder cells. DGT is expressed in shoot and root, and localizes to both the nucleus and cytoplasm during lateral root organogenesis. Mutation of ENTIRE/ IAA9, a member of the auxin-responsive Aux/IAA protein family of transcriptional repressors, partially restores the inability of dgt to initiate lateral root primordia but not the primordia outgrowth. By comparison, grafting of a wild-type scion restores the process of lateral root formation, consistent with participation of a mobile signal. Antibodies do not detect movement of the DGT protein into the dgt rootstock; however, experiments with radiolabeled auxin and an auxin-specific microelectrode demonstrate abnormal auxin fluxes. Functional studies of DGT in heterologous yeast and tobacco-leaf auxin-transport systems demonstrate that DGT negatively regulates PIN-FORMED (PIN) auxin efflux transporters by affecting their plasma membrane localization. Studies in tomato support complex effects of the dgt mutation on PIN expression level, expression domain and plasma membrane localization. Our data demonstrate that DGT regulates auxin transport in lateral root formation. author: - first_name: Maria full_name: Ivanchenko, Maria last_name: Ivanchenko - first_name: Jinsheng full_name: Zhu, Jinsheng last_name: Zhu - first_name: Bangjun full_name: Wang, Bangjun last_name: Wang - first_name: Eva full_name: Medvecka, Eva id: 298814E2-F248-11E8-B48F-1D18A9856A87 last_name: Medvecka - first_name: Yunlong full_name: Du, Yunlong last_name: Du - first_name: Elisa full_name: Azzarello, Elisa last_name: Azzarello - first_name: Stefano full_name: Mancuso, Stefano last_name: Mancuso - first_name: Molly full_name: Megraw, Molly last_name: Megraw - first_name: Sergei full_name: Filichkin, Sergei last_name: Filichkin - first_name: Joseph full_name: Dubrovsky, Joseph last_name: Dubrovsky - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Markus full_name: Geisler, Markus last_name: Geisler citation: ama: Ivanchenko M, Zhu J, Wang B, et al.

Auxin levels are sensed and interpreted by distinct receptor systems that activate a broad range of cellular responses. The Auxin-Binding Protein1 (ABP1) that has been identified based on its ability to bind auxin with high affinity is a prime candidate for the extracellular receptor responsible for mediating a range of auxin effects, in particular, the fast non-transcriptional ones. Contradictory genetic studies suggested prominent or no importance of ABP1 in many developmental processes. However, how crucial the role of auxin binding to ABP1 is for its functions has not been addressed. Here, we show that the auxin-binding pocket of ABP1 is essential for its gain-of-function cellular and developmental roles. In total, 16 different abp1 mutants were prepared that possessed substitutions in the metal core or in the hydrophobic amino acids of the auxin-binding pocket as well as neutral mutations. Their analysis revealed that an intact auxin-binding pocket is a prerequisite for ABP1 to activate downstream components of the ABP1 signalling pathway, such as Rho of Plants (ROPs) and to mediate the clathrin association with membranes for endocytosis regulation. In planta analyses demonstrated the importance of the auxin binding pocket for all known ABP1-mediated postembryonic developmental processes, including morphology of leaf epidermal cells, root growth and root meristem activity, and vascular tissue differentiation. Taken together, these findings suggest that auxin binding to ABP1 is central to its function, supporting the role of ABP1 as auxin receptor. acknowledgement: This work was supported by ERC Independent Research grant (ERC-2011-StG- 20101109-PSDP to JF); the European Social Fund and the state budget of the Czech Republic [the project ‘Employment of Newly Graduated Doctors of Science for Scientific Excellence’ (CZ.1.07/2.3.00/30.0009) to TN]; the Czech Science Foundation (GACR) [project 13-40637S to JF]. article_type: original author: - first_name: Peter full_name: Grones, Peter id: 399876EC-F248-11E8-B48F-1D18A9856A87 last_name: Grones - first_name: Xu full_name: Chen, Xu id: 4E5ADCAA-F248-11E8-B48F-1D18A9856A87 last_name: Chen - first_name: Sibu full_name: Simon, Sibu id: 4542EF9A-F248-11E8-B48F-1D18A9856A87 last_name: Simon orcid: 0000-0002-1998-6741 - first_name: Walter full_name: Kaufmann, Walter id: 3F99E422-F248-11E8-B48F-1D18A9856A87 last_name: Kaufmann orcid: 0000-0001-9735-5315 - first_name: Riet full_name: De Rycke, Riet last_name: De Rycke - first_name: Tomasz full_name: Nodzyński, Tomasz last_name: Nodzyński - first_name: Eva full_name: Zažímalová, Eva last_name: Zažímalová - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Grones P, Chen X, Simon S, et al.

Here we propose that AUXIN RESPONSE FACTOR7 (ARF7) and the ARF7-regulated FOUR LIPS/MYB124 (FLP) transcription factors jointly form a coherent feed-forward motif that mediates the auxin-responsive PIN3 transcription in planta to steer the early steps of lateral root formation. This regulatory mechanism might endow the PIN3 circuitry with a temporal 'memory' of auxin stimuli, potentially maintaining and enhancing the robustness of the auxin flux directionality during lateral root development. The cooperative action between canonical auxin signalling and other transcription factors might constitute a general mechanism by which transcriptional auxin-sensitivity can be regulated at a tissue-specific level. acknowledgement: 'of the European Research Council (project ERC-2011-StG-20101109-PSDP) (to J.F.), a FEBS long-term fellowship (to P.M.)

Auxin gradient establishment is mediated by polarly localized auxin transporters, including PIN-FORMED (PIN) proteins. Their localization and abundance at the plasma membrane are tightly regulated by endomembrane machinery, especially the endocytic and recycling pathways mediated by the ADP ribosylation factor guanine nucleotide exchange factor (ARF-GEF) GNOM. We assessed the role of the early secretory pathway in establishing PIN1 polarity in Arabidopsis thaliana by pharmacological and genetic approaches. We identified the compound endosidin 8 (ES8), which selectively interferes with PIN1 basal polarity without altering the polarity of apical proteins. ES8 alters the auxin distribution pattern in the root and induces a strong developmental phenotype, including reduced root length. The ARF-GEF- defective mutants gnom-like 1 ( gnl1-1) and gnom ( van7) are significantly resistant to ES8. The compound does not affect recycling or vacuolar trafficking of PIN1 but leads to its intracellular accumulation, resulting in loss of PIN1 basal polarity at the plasma membrane. Our data confirm a role for GNOM in endoplasmic reticulum (ER) - Golgi trafficking and reveal that a GNL1/GNOM-mediated early secretory pathway selectively regulates PIN1 basal polarity establishment in a manner essential for normal plant development. acknowledgement: 'This work was supported by Vetenskapsrådet and Vinnova (Verket för Innovationssystemet) (S.M.D., T.V., M.Ł., and S.R.), Knut och Alice Wallenbergs Stiftelse (S.M.D., A.R., and C.V.), Kempestiftelserna (A.H. and Q.M.), Carl Tryggers Stiftelse för Vetenskaplig Forskning (Q.M.), European Research Council Grant ERC-2011-StG-20101109-PSDP (to J.F.), US Department of Energy Grant DE-FG02-02ER15295 (to N.V.R.), and National Science Foundation Grant MCB-0817916 (to N.V.R. and G.R.H.).

Although cytokinin-mediated modulation of auxin distribution is a developmentally crucial hormonal interaction, its molecular basis is largely unknown. Here we show a direct regulatory link between cytokinin signalling and the auxin transport machinery uncovering a mechanistic framework for cytokinin-auxin cross-talk. We show that the CYTOKININ RESPONSE FACTORS (CRFs), transcription factors downstream of cytokinin perception, transcriptionally control genes encoding PIN-FORMED (PIN) auxin transporters at a specific PIN CYTOKININ RESPONSE ELEMENT (PCRE) domain. Removal of this cis-regulatory element effectively uncouples PIN transcription from the CRF-mediated cytokinin regulation and attenuates plant cytokinin sensitivity.

Changes in osmotic conditions disrupt the equilibrium of the plasma membrane: hypoosmotic conditions increase and hyperosmotic environment decrease the cell volume. Here, we show that short-term extracellular osmotic treatments are closely followed by a shift in the balance between endocytosis and exocytosis in root meristem cells. Acute hyperosmotic treatments (ionic and nonionic) enhance clathrin-mediated endocytosis simultaneously attenuating exocytosis, whereas hypoosmotic treatments have the opposite effects. In addition to clathrin recruitment to the plasma membrane, components of early endocytic trafficking are essential during hyperosmotic stress responses. Consequently, growth of seedlings defective in elements of clathrin or early endocytic machinery is more sensitive to hyperosmotic treatments. We also found that the endocytotic response to a change of osmotic status in the environment is dominant over the presumably evolutionary more recent regulatory effect of plant hormones, such as auxin. These results imply that osmotic perturbation influences the balance between endocytosis and exocytosis acting through clathrin-mediated endocytosis. We propose that tension on the plasma membrane determines the addition or removal of membranes at the cell surface, thus preserving cell integrity.' acknowledgement: This work was supported by the European Research Council (project ERC-2011-StG-20101109-PSDP); European Social Fund (CZ.1.07/2.3.00/20.0043) and the Czech Science Foundation GAČR (GA13-40637S) to J.F.; project Postdoc I.

Although the role of PIN auxin efflux transporters has been clearly assigned during embryonic shoot and root specification, the role of the auxin influx carriers AUX1 and LIKE-AUX1 (LAX) proteins is not well established. Here, we used chemical and genetic tools on Brassica napus microspore-derived embryos and Arabidopsis thaliana zygotic embryos, and demonstrate that AUX1, LAX1 and LAX2 are required for both shoot and root pole formation, in concert with PIN efflux carriers. Furthermore, we uncovered a positive-feedback loop betweenMONOPTEROS(ARF5)-dependent auxin signalling and auxin transport. ThisMONOPTEROSdependent transcriptional regulation of auxin influx (AUX1, LAX1 and LAX2) and auxin efflux (PIN1 and PIN4) carriers by MONOPTEROS helps to maintain proper auxin transport to the root tip. These results indicate that auxin-dependent cell specification during embryo development requires balanced auxin transport involving both influx and efflux mechanisms, and that this transport is maintained by a positive transcriptional feedback on auxin signalling. acknowledgement: W.G. is a post-doctoral fellow of the Research Foundation Flanders.

Differences in auxin distribution within tissues are mediated by the polar auxin transport machinery, and cellular auxin responses occur depending on changes in cellular auxin levels. Multiple receptor systems at the cell surface and in the interior operate to sense and interpret fluctuations in auxin distribution that occur during plant development. Until now, three proteins or protein complexes that can bind auxin have been identified. SCFTIR1 [a SKP1-cullin-1-F-box complex that contains transport inhibitor response 1 (TIR1) as the F-box protein] and S-phase-kinaseassociated protein 2 (SKP2) localize to the nucleus, whereas auxinbinding protein 1 (ABP1), predominantly associates with the endoplasmic reticulum and cell surface. In this Cell Science at a Glance article, we summarize recent discoveries in the field of auxin transport and signaling that have led to the identification of new components of these pathways, as well as their mutual interaction. acknowledgement: This work was supported by the European Research Council [project ERC-2011-StG-20101109-PSDP]; European Social Fund [grant number CZ.1.07/2.3.00/20.0043] and the Czech Science Foundation GAČR [grant number GA13-40637S] author: - first_name: Peter full_name: Grones, Peter id: 399876EC-F248-11E8-B48F-1D18A9856A87 last_name: Grones - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Grones P, Friml J.

Over the last 80 years EM has vastly increased our understanding of the complex cellular structures that underlie the diverse functions that cells need to maintain life. One drawback that has been difficult to overcome was the inherent lack of volume information, mainly due to the limit on the thickness of sections that could be viewed in a transmission electron microscope (TEM). For many years scientists struggled to achieve three-dimensional (3D) EM using serial section reconstructions, TEM tomography, and scanning EM (SEM) techniques such as freeze-fracture. Although each technique yielded some special information, they required a significant amount of time and specialist expertise to obtain even a very small 3D EM dataset. Almost 20 years ago scientists began to exploit SEMs to image blocks of embedded tissues and perform serial sectioning of these tissues inside the SEM chamber. Using first focused ion beams (FIB) and subsequently robotic ultramicrotomes (serial block-face, SBF-SEM) microscopists were able to collect large volumes of 3D EM information at resolutions that could address many important biological questions, and do so in an efficient manner. We present here some examples of 3D EM taken from the many diverse specimens that have been imaged in our core facility. We propose that the next major step forward will be to efficiently correlate functional information obtained using light microscopy (LM) with 3D EM datasets to more completely investigate the important links between cell structures and their functions. acknowledgement: The Zeiss Merlin with Gatan 3View2XP and Zeiss Auriga were acquired through a CLEM grant from Minister Ingrid Lieten to the VIB Bio-Imaging-Core.
