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.","lang":"eng"}],"status":"public","file_date_updated":"2020-07-14T12:47:54Z","date_created":"2018-12-11T11:48:08Z","article_processing_charge":"No","ec_funded":1,"publication_identifier":{"issn":["09609822"]},"pubrep_id":"982","publication":"Current Biology","publist_id":"6956","scopus_import":"1","month":"09","pmid":1,"tmp":{"short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode"},"_id":"722","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","citation":{"ieee":"E.

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"}],"intvolume":" 9","date_updated":"2025-09-22T14:08:07Z","oa_version":"Published Version","author":[{"first_name":"Tomasz","full_name":"Nodzyński, Tomasz","last_name":"Nodzyński"},{"first_name":"Steffen","last_name":"Vanneste","full_name":"Vanneste, Steffen"},{"first_name":"Marta","full_name":"Zwiewka, Marta","last_name":"Zwiewka"},{"first_name":"Markéta","full_name":"Pernisová, Markéta","last_name":"Pernisová"},{"first_name":"Jan","full_name":"Hejátko, Jan","last_name":"Hejátko"},{"last_name":"Friml","full_name":"Friml, Jirí","first_name":"Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8302-7596"}],"issue":"11","publisher":"Cell Press","date_published":"2016-11-07T00:00:00Z","doi":"10.1016/j.molp.2016.08.010","language":[{"iso":"eng"}],"oa":1,"file":[{"date_created":"2018-12-12T10:13:22Z","relation":"main_file","creator":"system","file_name":"IST-2017-746-v1+1_1-s2.0-S1674205216301915-main.pdf","access_level":"open_access","file_id":"5004","file_size":5005876,"content_type":"application/pdf","date_updated":"2018-12-12T10:13:22Z"}],"year":"2016","quality_controlled":"1","page":"1504 - 1519","external_id":{"isi":["000389594100008"]},"_id":"1145","tmp":{"short":"CC BY-NC-ND (4.0)","image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode"},"month":"11","scopus_import":"1","publist_id":"6213","type":"journal_article","volume":9,"citation":{"ieee":"T.

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.","lang":"eng"}],"author":[{"full_name":"Simonini, Sara","last_name":"Simonini","first_name":"Sara"},{"first_name":"Joyita","last_name":"Deb","full_name":"Deb, Joyita"},{"full_name":"Moubayidin, Laila","last_name":"Moubayidin","first_name":"Laila"},{"last_name":"Stephenson","full_name":"Stephenson, Pauline","first_name":"Pauline"},{"full_name":"Valluru, Manoj","last_name":"Valluru","first_name":"Manoj"},{"first_name":"Alejandra","last_name":"Freire Rios","full_name":"Freire Rios, Alejandra"},{"first_name":"Karim","full_name":"Sorefan, Karim","last_name":"Sorefan"},{"first_name":"Dolf","last_name":"Weijers","full_name":"Weijers, Dolf"},{"last_name":"Friml","full_name":"Friml, Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87","first_name":"Jirí","orcid":"0000-0002-8302-7596"},{"full_name":"Östergaard, Lars","last_name":"Östergaard","first_name":"Lars"}],"oa":1,"file":[{"success":1,"creator":"dernst","relation":"main_file","date_created":"2019-01-25T09:32:55Z","file_size":1419263,"date_updated":"2019-01-25T09:32:55Z","content_type":"application/pdf","access_level":"open_access","file_name":"2016_GeneDev_Simonini.pdf","file_id":"5882"}],"issue":"20","publisher":"Cold Spring Harbor Laboratory Press","language":[{"iso":"eng"}],"date_published":"2016-10-15T00:00:00Z","doi":"10.1101/gad.285361.116","year":"2016","quality_controlled":"1","external_id":{"pmid":["27898393"],"isi":["000387814000005"]},"page":"2286 - 2296","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"_id":"1151","publist_id":"6207","month":"10","scopus_import":"1","pmid":1,"citation":{"ieee":"S.

A prominent example of the developmental processes based on differential cell growth is the formation of the apical hook that protects the fragile shoot apical meristem when it breaks through the soil during germination. 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","lang":"eng"}],"author":[{"last_name":"Rakusová","full_name":"Rakusová, Hana","first_name":"Hana"},{"id":"47E8FC1C-F248-11E8-B48F-1D18A9856A87","first_name":"Mohamad","last_name":"Abbas","full_name":"Abbas, Mohamad"},{"full_name":"Han, Huibin","last_name":"Han","id":"31435098-F248-11E8-B48F-1D18A9856A87","first_name":"Huibin"},{"last_name":"Song","full_name":"Song, Siyuan","first_name":"Siyuan"},{"full_name":"Robert, Hélène","last_name":"Robert","first_name":"Hélène"},{"last_name":"Friml","full_name":"Friml, Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87","first_name":"Jirí","orcid":"0000-0002-8302-7596"}],"article_processing_charge":"No","status":"public","file_date_updated":"2020-07-14T12:44:39Z","date_created":"2018-12-11T11:50:44Z","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."}],"author":[{"id":"483727CA-F248-11E8-B48F-1D18A9856A87","first_name":"Jaroslav","last_name":"Michalko","full_name":"Michalko, Jaroslav"},{"orcid":"0000-0003-0619-7783","first_name":"Matous","id":"1AE1EA24-02D0-11E9-9BAA-DAF4881429F2","full_name":"Glanc, Matous","last_name":"Glanc"},{"last_name":"Perrot Rechenmann","full_name":"Perrot Rechenmann, Catherine","first_name":"Catherine"},{"full_name":"Friml, Jirí","last_name":"Friml","orcid":"0000-0002-8302-7596","first_name":"Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87"}],"article_processing_charge":"No","date_created":"2018-12-11T11:50:47Z","file_date_updated":"2020-07-14T12:44:39Z","status":"public","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."}],"date_updated":"2025-09-22T09:18:11Z","intvolume":" 6","oa_version":"Published Version","article_number":"1262","author":[{"orcid":"0000-0002-6862-1247","id":"49E91952-F248-11E8-B48F-1D18A9856A87","first_name":"Daniel","full_name":"Von Wangenheim, Daniel","last_name":"Von Wangenheim"},{"last_name":"Rosero","full_name":"Rosero, Amparo","first_name":"Amparo"},{"first_name":"George","last_name":"Komis","full_name":"Komis, George"},{"last_name":"Šamajová","full_name":"Šamajová, Olga","first_name":"Olga"},{"full_name":"Ovečka, Miroslav","last_name":"Ovečka","first_name":"Miroslav"},{"last_name":"Voigt","full_name":"Voigt, Boris","first_name":"Boris"},{"last_name":"Šamaj","full_name":"Šamaj, Jozef","first_name":"Jozef"}],"department":[{"_id":"JiFr"}],"isi":1,"has_accepted_license":"1","day":"29","ddc":["581"],"title":"Endosomal interactions during root hair growth","publication":"Frontiers in Plant Science","pubrep_id":"710","article_processing_charge":"No","acknowledgement":"This work was supported by National Program for Sustainability I (grant no.

Phosphorylation dynamics of PIN proteins are affected by the protein phosphatase 2A (PP2A) and the PINOID kinase, which act antagonistically to mediate their apical-basal polar delivery. Here, we identified the ROTUNDA3 (RON3) protein as a regulator of the PP2A phosphatase activity in Arabidopsis thaliana. 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."}],"status":"public","main_file_link":[{"open_access":"1","url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4791031/"}],"date_created":"2018-12-11T11:50:56Z","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."}],"author":[{"first_name":"Jinsheng","last_name":"Zhu","full_name":"Zhu, Jinsheng"},{"last_name":"Bailly","full_name":"Bailly, Aurélien","first_name":"Aurélien"},{"first_name":"Marta","last_name":"Zwiewka","full_name":"Zwiewka, Marta"},{"last_name":"Sovero","full_name":"Sovero, Valpuri","first_name":"Valpuri"},{"last_name":"Di Donato","full_name":"Di Donato, Martin","first_name":"Martin"},{"last_name":"Ge","full_name":"Ge, Pei","first_name":"Pei"},{"last_name":"Oehri","full_name":"Oehri, Jacqueline","first_name":"Jacqueline"},{"first_name":"Bibek","last_name":"Aryal","full_name":"Aryal, Bibek"},{"first_name":"Pengchao","last_name":"Hao","full_name":"Hao, Pengchao"},{"last_name":"Linnert","full_name":"Linnert, Miriam","first_name":"Miriam"},{"first_name":"Noelia","last_name":"Burgardt","full_name":"Burgardt, Noelia"},{"last_name":"Lücke","full_name":"Lücke, Christian","first_name":"Christian"},{"last_name":"Weiwad","full_name":"Weiwad, Matthias","first_name":"Matthias"},{"last_name":"Michel","full_name":"Michel, Max","first_name":"Max"},{"last_name":"Weiergräber","full_name":"Weiergräber, Oliver","first_name":"Oliver"},{"first_name":"Stephan","last_name":"Pollmann","full_name":"Pollmann, Stephan"},{"first_name":"Elisa","last_name":"Azzarello","full_name":"Azzarello, Elisa"},{"last_name":"Mancuso","full_name":"Mancuso, Stefano","first_name":"Stefano"},{"full_name":"Ferro, Noel","last_name":"Ferro","first_name":"Noel"},{"last_name":"Fukao","full_name":"Fukao, Yoichiro","first_name":"Yoichiro"},{"first_name":"Céline","last_name":"Hoffmann","full_name":"Hoffmann, Céline"},{"first_name":"Roland","full_name":"Wedlich Söldner, Roland","last_name":"Wedlich Söldner"},{"orcid":"0000-0002-8302-7596","first_name":"Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jirí","last_name":"Friml"},{"first_name":"Clément","last_name":"Thomas","full_name":"Thomas, Clément"},{"last_name":"Geisler","full_name":"Geisler, Markus","first_name":"Markus"}],"article_processing_charge":"No","status":"public","main_file_link":[{"open_access":"1","url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4863381/"}],"date_created":"2018-12-11T11:50:57Z","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.","lang":"eng"}],"oa_version":"Submitted Version","intvolume":" 171","date_updated":"2025-09-22T08:58:52Z","author":[{"full_name":"Sancho Andrés, Gloria","last_name":"Sancho Andrés","first_name":"Gloria"},{"full_name":"Soriano Ortega, Esther","last_name":"Soriano Ortega","first_name":"Esther"},{"last_name":"Gao","full_name":"Gao, Caiji","first_name":"Caiji"},{"full_name":"Bernabé Orts, Joan","last_name":"Bernabé Orts","first_name":"Joan"},{"full_name":"Narasimhan, Madhumitha","last_name":"Narasimhan","orcid":"0000-0002-8600-0671","id":"44BF24D0-F248-11E8-B48F-1D18A9856A87","first_name":"Madhumitha"},{"full_name":"Müller, Anna","last_name":"Müller","id":"420AB15A-F248-11E8-B48F-1D18A9856A87","first_name":"Anna"},{"first_name":"Ricardo","last_name":"Tejos","full_name":"Tejos, Ricardo"},{"first_name":"Liwen","last_name":"Jiang","full_name":"Jiang, Liwen"},{"orcid":"0000-0002-8302-7596","first_name":"Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jirí","last_name":"Friml"},{"first_name":"Fernando","full_name":"Aniento, Fernando","last_name":"Aniento"},{"first_name":"Maria","last_name":"Marcote","full_name":"Marcote, Maria"}],"department":[{"_id":"JiFr"},{"_id":"EvBe"}],"project":[{"name":"Polarity and subcellular dynamics in plants","_id":"25716A02-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","grant_number":"282300"}],"isi":1,"day":"01","title":"Sorting motifs involved in the trafficking and localization of the PIN1 auxin efflux carrier","publication":"Plant Physiology","ec_funded":1,"article_processing_charge":"No","acknowledgement":"We thank Dr. R.

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."}],"date_created":"2018-12-11T11:51:05Z","status":"public","file_date_updated":"2020-07-14T12:44:42Z","acknowledgement":"We wish to thank Prof. Ewa U.

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","lang":"eng"}],"intvolume":" 113","date_updated":"2025-09-22T08:37:42Z","oa_version":"Preprint","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."}],"author":[{"id":"43905548-F248-11E8-B48F-1D18A9856A87","first_name":"Matyas","orcid":"0000-0002-9767-8699","last_name":"Fendrych","full_name":"Fendrych, Matyas"},{"last_name":"Leung","full_name":"Leung, Jeffrey","first_name":"Jeffrey"},{"full_name":"Friml, Jirí","last_name":"Friml","orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87","first_name":"Jirí"}],"oa":1,"file":[{"creator":"system","relation":"main_file","date_created":"2018-12-12T10:09:24Z","content_type":"application/pdf","date_updated":"2020-07-14T12:44:45Z","file_size":5666343,"file_id":"4748","file_name":"IST-2016-693-v1+1_e19048-download.pdf","checksum":"9209541fbba00f24daad21a5d568540d","access_level":"open_access"}],"date_published":"2016-09-14T00:00:00Z","language":[{"iso":"eng"}],"doi":"10.7554/eLife.19048","publisher":"eLife Sciences Publications","year":"2016","quality_controlled":"1","external_id":{"isi":["000385559100001"]},"tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"_id":"1344","publist_id":"5908","scopus_import":"1","month":"09","citation":{"short":"M.

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.","lang":"eng"}],"article_number":"11710","oa_version":"Published Version","date_updated":"2026-04-08T13:54:44Z","intvolume":" 7","ddc":["570"],"day":"08","title":"Mitochondrial uncouplers inhibit clathrin-mediated endocytosis largely through cytoplasmic acidification","department":[{"_id":"JiFr"}],"project":[{"_id":"25716A02-B435-11E9-9278-68D0E5697425","grant_number":"282300","call_identifier":"FP7","name":"Polarity and subcellular dynamics in plants"}],"has_accepted_license":"1","isi":1,"pubrep_id":"653","ec_funded":1,"related_material":{"record":[{"relation":"dissertation_contains","id":"7172","status":"public"}]},"publication":"Nature Communications","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.

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.","lang":"eng"}]},{"status":"public","file_date_updated":"2020-07-14T12:44:53Z","date_created":"2018-12-11T11:51:51Z","acknowledgement":"the Odysseus Program of the Research Foundation-Flanders [G091608] to JF.","article_processing_charge":"No","pubrep_id":"1005","publication":"Plant Science","title":"Phosphatidylinositol 4-phosphate 5-kinases 1 and 2 are involved in the regulation of vacuole morphology during Arabidopsis thaliana pollen development","day":"01","ddc":["581"],"has_accepted_license":"1","isi":1,"department":[{"_id":"JiFr"}],"author":[{"last_name":"Ugalde","full_name":"Ugalde, José","first_name":"José"},{"first_name":"Cecilia","full_name":"Rodríguez Furlán, Cecilia","last_name":"Rodríguez Furlán"},{"first_name":"Riet","last_name":"De Rycke","full_name":"De Rycke, Riet"},{"full_name":"Norambuena, Lorena","last_name":"Norambuena","first_name":"Lorena"},{"orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87","first_name":"Jirí","full_name":"Friml, Jirí","last_name":"Friml"},{"last_name":"León","full_name":"León, Gabriel","first_name":"Gabriel"},{"first_name":"Ricardo","last_name":"Tejos","full_name":"Tejos, Ricardo"}],"date_updated":"2025-09-18T14:29:16Z","intvolume":" 250","oa_version":"Submitted Version","abstract":[{"lang":"eng","text":"The pollen grains arise after meiosis of pollen mother cells within the anthers. 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."}],"oa":1,"file":[{"relation":"main_file","creator":"dernst","date_created":"2019-04-17T07:41:57Z","content_type":"application/pdf","date_updated":"2020-07-14T12:44:53Z","file_size":4338545,"file_id":"6331","file_name":"2016_PlantScience_Ugalde.pdf","access_level":"open_access","checksum":"ca08de036e6ddc81e6f760e0ccdebd3f"}],"date_published":"2016-09-01T00:00:00Z","language":[{"iso":"eng"}],"publisher":"Elsevier","doi":"10.1016/j.plantsci.2016.05.014","external_id":{"pmid":["27457979"],"isi":["000381545000002"]},"page":"10 - 19","year":"2016","quality_controlled":"1","publist_id":"5797","month":"09","scopus_import":"1","pmid":1,"_id":"1410","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","citation":{"apa":"Ugalde, J., Rodríguez Furlán, C., De Rycke, R., Norambuena, L., Friml, J., León, G., & Tejos, R.

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."}],"title":"PIN6 auxin transporter at endoplasmic reticulum and plasma membrane mediates auxin homeostasis and organogenesis in Arabidopsis","ddc":["581"],"day":"01","has_accepted_license":"1","isi":1,"department":[{"_id":"JiFr"}],"pubrep_id":"1004","publication":"New Phytologist","date_created":"2018-12-11T11:51:54Z","file_date_updated":"2020-07-14T12:44:53Z","status":"public","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 GACR (project no. 13-4063 7S to J.F.)","article_processing_charge":"No","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publication_status":"published","citation":{"ama":"Simon S, Skůpa P, Viaene T, et al.
