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."}],"article_number":"1262","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","issue":"JAN2016","scopus_import":"1","_id":"1238","department":[{"_id":"JiFr"}],"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.","lang":"eng"}],"external_id":{"isi":["000372013300055"]},"project":[{"_id":"25716A02-B435-11E9-9278-68D0E5697425","name":"Polarity and subcellular dynamics in plants","call_identifier":"FP7","grant_number":"282300"}],"status":"public","day":"08","author":[{"first_name":"Michael","last_name":"Karampelias","full_name":"Karampelias, Michael"},{"first_name":"Pia","last_name":"Neyt","full_name":"Neyt, Pia"},{"full_name":"De Groeve, Steven","last_name":"De Groeve","first_name":"Steven"},{"first_name":"Stijn","full_name":"Aesaert, Stijn","last_name":"Aesaert"},{"full_name":"Coussens, Griet","last_name":"Coussens","first_name":"Griet"},{"last_name":"Rolčík","full_name":"Rolčík, Jakub","first_name":"Jakub"},{"full_name":"Bruno, Leonardo","last_name":"Bruno","first_name":"Leonardo"},{"last_name":"De Winne","full_name":"De Winne, Nancy","first_name":"Nancy"},{"first_name":"Annemie","full_name":"Van Minnebruggen, Annemie","last_name":"Van Minnebruggen"},{"last_name":"Van Montagu","full_name":"Van Montagu, Marc","first_name":"Marc"},{"first_name":"Maria","full_name":"Ponce, Maria","last_name":"Ponce"},{"last_name":"Micol","full_name":"Micol, José","first_name":"José"},{"first_name":"Jirí","orcid":"0000-0002-8302-7596","last_name":"Friml","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jirí"},{"last_name":"De Jaeger","full_name":"De Jaeger, Geert","first_name":"Geert"},{"first_name":"Mieke","full_name":"Van Lijsebettens, Mieke","last_name":"Van Lijsebettens"}],"language":[{"iso":"eng"}],"year":"2016","type":"journal_article","date_updated":"2025-09-22T09:13:28Z","fulldoi":"https://doi.org/10.1073/pnas.1501343112","date_created":"2018-12-11T11:50:56Z","publication":"PNAS","publication_status":"published","publist_id":"6081","intvolume":" 113","isi":1,"volume":113,"oa":1,"month":"03","article_processing_charge":"No","title":"ROTUNDA3 function in plant development by phosphatase 2A-mediated regulation of auxin transporter recycling","doi":"10.1073/pnas.1501343112","date_published":"2016-03-08T00:00:00Z","page":"2768 - 2773","quality_controlled":"1","main_file_link":[{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4791031/","open_access":"1"}],"oa_version":"Submitted Version"},{"year":"2016","type":"journal_article","date_updated":"2025-09-22T09:10:52Z","date_created":"2018-12-11T11:50:57Z","fulldoi":"https://doi.org/10.1105/tpc.15.00726","publist_id":"6078","publication":"Plant Cell","publication_status":"published","intvolume":" 28","volume":28,"isi":1,"oa":1,"month":"04","article_processing_charge":"No","title":"TWISTED DWARF1 mediates the action of auxin transport inhibitors on actin cytoskeleton dynamics","doi":"10.1105/tpc.15.00726","date_published":"2016-04-01T00:00:00Z","page":"930 - 948","main_file_link":[{"open_access":"1","url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4863381/"}],"quality_controlled":"1","oa_version":"Submitted Version","publisher":"American Society of Plant Biologists","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.).

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.","lang":"eng"}],"external_id":{"isi":["000375416000012"]},"status":"public","day":"01","author":[{"first_name":"Jinsheng","full_name":"Zhu, Jinsheng","last_name":"Zhu"},{"first_name":"Aurélien","last_name":"Bailly","full_name":"Bailly, Aurélien"},{"full_name":"Zwiewka, Marta","last_name":"Zwiewka","first_name":"Marta"},{"last_name":"Sovero","full_name":"Sovero, Valpuri","first_name":"Valpuri"},{"first_name":"Martin","full_name":"Di Donato, Martin","last_name":"Di Donato"},{"first_name":"Pei","last_name":"Ge","full_name":"Ge, Pei"},{"last_name":"Oehri","full_name":"Oehri, Jacqueline","first_name":"Jacqueline"},{"last_name":"Aryal","full_name":"Aryal, Bibek","first_name":"Bibek"},{"last_name":"Hao","full_name":"Hao, Pengchao","first_name":"Pengchao"},{"full_name":"Linnert, Miriam","last_name":"Linnert","first_name":"Miriam"},{"first_name":"Noelia","last_name":"Burgardt","full_name":"Burgardt, Noelia"},{"first_name":"Christian","full_name":"Lücke, Christian","last_name":"Lücke"},{"first_name":"Matthias","full_name":"Weiwad, Matthias","last_name":"Weiwad"},{"full_name":"Michel, Max","last_name":"Michel","first_name":"Max"},{"last_name":"Weiergräber","full_name":"Weiergräber, Oliver","first_name":"Oliver"},{"last_name":"Pollmann","full_name":"Pollmann, Stephan","first_name":"Stephan"},{"last_name":"Azzarello","full_name":"Azzarello, Elisa","first_name":"Elisa"},{"last_name":"Mancuso","full_name":"Mancuso, Stefano","first_name":"Stefano"},{"first_name":"Noel","last_name":"Ferro","full_name":"Ferro, Noel"},{"full_name":"Fukao, Yoichiro","last_name":"Fukao","first_name":"Yoichiro"},{"first_name":"Céline","last_name":"Hoffmann","full_name":"Hoffmann, Céline"},{"first_name":"Roland","last_name":"Wedlich Söldner","full_name":"Wedlich Söldner, Roland"},{"orcid":"0000-0002-8302-7596","first_name":"Jirí","last_name":"Friml","full_name":"Friml, Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Clément","full_name":"Thomas, Clément","last_name":"Thomas"},{"first_name":"Markus","last_name":"Geisler","full_name":"Geisler, Markus"}],"language":[{"iso":"eng"}]},{"citation":{"chicago":"Sancho Andrés, Gloria, Esther Soriano Ortega, Caiji Gao, Joan Bernabé Orts, Madhumitha Narasimhan, Anna Müller, Ricardo Tejos, et al. “Sorting Motifs Involved in the Trafficking and Localization of the PIN1 Auxin Efflux Carrier.” Plant Physiology.

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"}],"day":"01","language":[{"iso":"eng"}],"author":[{"first_name":"Gloria","last_name":"Sancho Andrés","full_name":"Sancho Andrés, Gloria"},{"first_name":"Esther","full_name":"Soriano Ortega, Esther","last_name":"Soriano Ortega"},{"first_name":"Caiji","last_name":"Gao","full_name":"Gao, Caiji"},{"full_name":"Bernabé Orts, Joan","last_name":"Bernabé Orts","first_name":"Joan"},{"orcid":"0000-0002-8600-0671","first_name":"Madhumitha","last_name":"Narasimhan","id":"44BF24D0-F248-11E8-B48F-1D18A9856A87","full_name":"Narasimhan, Madhumitha"},{"last_name":"Müller","full_name":"Müller, Anna","id":"420AB15A-F248-11E8-B48F-1D18A9856A87","first_name":"Anna"},{"first_name":"Ricardo","full_name":"Tejos, Ricardo","last_name":"Tejos"},{"last_name":"Jiang","full_name":"Jiang, Liwen","first_name":"Liwen"},{"orcid":"0000-0002-8302-7596","first_name":"Jirí","last_name":"Friml","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jirí"},{"full_name":"Aniento, Fernando","last_name":"Aniento","first_name":"Fernando"},{"first_name":"Maria","full_name":"Marcote, Maria","last_name":"Marcote"}],"status":"public","project":[{"grant_number":"282300","_id":"25716A02-B435-11E9-9278-68D0E5697425","name":"Polarity and subcellular dynamics in plants","call_identifier":"FP7"}],"date_updated":"2025-09-22T08:58:52Z","publication_status":"published","publication":"Plant Physiology","publist_id":"6059","fulldoi":"https://doi.org/10.1104/pp.16.00373","date_created":"2018-12-11T11:51:01Z","type":"journal_article","year":"2016","isi":1,"volume":171,"intvolume":" 171","article_processing_charge":"No","title":"Sorting motifs involved in the trafficking and localization of the PIN1 auxin efflux carrier","oa":1,"month":"07","page":"1965 - 1982","oa_version":"Submitted Version","quality_controlled":"1","main_file_link":[{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4936568/","open_access":"1"}],"doi":"10.1104/pp.16.00373","date_published":"2016-07-01T00:00:00Z"},{"acknowledgement":"We wish to thank Prof. Ewa U.

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."}],"external_id":{"isi":["000383572400003"],"pmid":["27649687"]},"day":"21","pubrep_id":"692","file_date_updated":"2020-07-14T12:44:42Z","author":[{"first_name":"Ewa","last_name":"Mazur","full_name":"Mazur, Ewa"},{"last_name":"Benková","full_name":"Benková, Eva","id":"38F4F166-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8510-9739","first_name":"Eva"},{"full_name":"Friml, Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87","last_name":"Friml","orcid":"0000-0002-8302-7596","first_name":"Jirí"}],"language":[{"iso":"eng"}],"status":"public","date_updated":"2025-09-22T08:43:50Z","fulldoi":"https://doi.org/10.1038/srep33754","date_created":"2018-12-11T11:51:05Z","file":[{"file_size":2895147,"file_id":"5008","checksum":"ee371fbc9124ad93157a95829264e4fe","access_level":"open_access","date_created":"2018-12-12T10:13:25Z","date_updated":"2020-07-14T12:44:42Z","file_name":"IST-2016-692-v1+1_srep33754.pdf","content_type":"application/pdf","creator":"system","relation":"main_file"}],"publication":"Scientific Reports","publist_id":"6042","publication_status":"published","year":"2016","type":"journal_article","related_material":{"record":[{"relation":"later_version","status":"public","id":"545"}]},"isi":1,"volume":6,"intvolume":" 6","article_processing_charge":"No","title":"Vascular cambium regeneration and vessel formation in wounded inflorescence stems of Arabidopsis","oa":1,"month":"09","has_accepted_license":"1","tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"pmid":1,"quality_controlled":"1","ddc":["581"],"oa_version":"Published Version","doi":"10.1038/srep33754","date_published":"2016-09-21T00:00:00Z"},{"author":[{"first_name":"Fausto","last_name":"Ortiz Morea","full_name":"Ortiz Morea, Fausto"},{"first_name":"Daniel","last_name":"Savatin","full_name":"Savatin, Daniel"},{"last_name":"Dejonghe","full_name":"Dejonghe, Wim","first_name":"Wim"},{"first_name":"Rahul","last_name":"Kumar","full_name":"Kumar, Rahul"},{"full_name":"Luo, Yu","last_name":"Luo","first_name":"Yu"},{"full_name":"Adamowski, Maciek","id":"45F536D2-F248-11E8-B48F-1D18A9856A87","last_name":"Adamowski","orcid":"0000-0001-6463-5257","first_name":"Maciek"},{"first_name":"Jos","full_name":"Van Begin, Jos","last_name":"Van Begin"},{"first_name":"Keini","last_name":"Dressano","full_name":"Dressano, Keini"},{"last_name":"De Oliveira","full_name":"De Oliveira, Guilherme","first_name":"Guilherme"},{"last_name":"Zhao","full_name":"Zhao, Xiuyang","first_name":"Xiuyang"},{"first_name":"Qing","last_name":"Lu","full_name":"Lu, Qing"},{"first_name":"Annemieke","full_name":"Madder, Annemieke","last_name":"Madder"},{"full_name":"Friml, Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87","last_name":"Friml","first_name":"Jirí","orcid":"0000-0002-8302-7596"},{"first_name":"Daniel","full_name":"De Moura, Daniel","last_name":"De Moura"},{"first_name":"Eugenia","last_name":"Russinova","full_name":"Russinova, Eugenia"}],"language":[{"iso":"eng"}],"day":"27","status":"public","external_id":{"isi":["000383954700066"]},"abstract":[{"text":"The Arabidopsis thaliana endogenous elicitor peptides (AtPeps) are released into the apoplast after cellular damage caused by pathogens or wounding to induce innate immunity by direct binding to the membrane-localized leucine-rich repeat receptor kinases, PEP RECEPTOR1 (PEPR1) and PEPR2. 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"}],"user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","issue":"39","_id":"1277","department":[{"_id":"JiFr"}],"scopus_import":"1","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."}],"external_id":{"isi":["000385559100001"]}},{"quality_controlled":"1","ddc":["581"],"oa_version":"Published Version","has_accepted_license":"1","corr_author":"1","date_published":"2016-07-01T00:00:00Z","doi":"10.1038/nplants.2016.102","title":"Plasma membrane: Negative attraction","article_processing_charge":"No","month":"07","oa":1,"volume":2,"isi":1,"intvolume":" 2","fulldoi":"https://doi.org/10.1038/nplants.2016.102","date_created":"2018-12-11T11:51:30Z","file":[{"creator":"system","content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_size":127781,"file_id":"4954","checksum":"9ba65f558563b287f875f48fa9f30fb2","date_updated":"2020-07-14T12:44:45Z","file_name":"IST-2018-1007-v1+1_Molnar_NatPlants_2016.pdf","date_created":"2018-12-12T10:12:36Z"},{"creator":"system","content_type":"application/pdf","relation":"main_file","file_size":430556,"file_id":"4955","checksum":"550d252be808d8ca2b43e83dddb4212f","access_level":"open_access","date_created":"2018-12-12T10:12:37Z","date_updated":"2020-07-14T12:44:45Z","file_name":"IST-2018-1007-v1+2_Molnar_NatPlants_2016_editor_statement.pdf"}],"publist_id":"5907","publication_status":"published","publication":"Nature Plants","date_updated":"2025-09-22T08:15:28Z","year":"2016","type":"journal_article","author":[{"first_name":"Gergely","last_name":"Molnar","full_name":"Molnar, Gergely","id":"34F1AF46-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Matyas","orcid":"0000-0002-9767-8699","full_name":"Fendrych, Matyas","id":"43905548-F248-11E8-B48F-1D18A9856A87","last_name":"Fendrych"},{"last_name":"Friml","full_name":"Friml, Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87","first_name":"Jirí","orcid":"0000-0002-8302-7596"}],"language":[{"iso":"eng"}],"day":"01","file_date_updated":"2020-07-14T12:44:45Z","pubrep_id":"1007","status":"public","abstract":[{"text":"The electrostatic charge at the inner surface of the plasma membrane is strongly negative in higher organisms.

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"}],"external_id":{"isi":["000377899800001"]}},{"title":"Cytokinins influence root gravitropism via differential regulation of auxin transporter expression and localization in Arabidopsis","article_processing_charge":"No","month":"10","oa":1,"quality_controlled":"1","ddc":["581"],"oa_version":"Submitted Version","has_accepted_license":"1","page":"497 - 509","date_published":"2016-10-01T00:00:00Z","doi":"10.1111/nph.14049","file":[{"date_created":"2018-12-12T10:14:53Z","date_updated":"2020-07-14T12:44:47Z","file_name":"IST-2018-1006-v1+1_Pernisova_NewPhytol_2016_peer_review.pdf","file_id":"5108","file_size":972763,"checksum":"27fd841ceaf0403559d7048ef51500f9","access_level":"open_access","relation":"main_file","creator":"system","content_type":"application/pdf"}],"fulldoi":"https://doi.org/10.1111/nph.14049","date_created":"2018-12-11T11:51:38Z","publication":"New Phytologist","publist_id":"5839","publication_status":"published","date_updated":"2025-09-22T07:36:11Z","year":"2016","type":"journal_article","isi":1,"volume":212,"intvolume":" 212","external_id":{"isi":["000383595700023"]},"abstract":[{"text":"Redirection of intercellular auxin fluxes via relocalization of the PIN-FORMED 3 (PIN3) and PIN7 auxin efflux carriers has been suggested to be necessary for the root gravitropic response. 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"}],"author":[{"full_name":"Pernisová, Markéta","last_name":"Pernisová","first_name":"Markéta"},{"first_name":"Tomas","id":"3DA3BFEE-F248-11E8-B48F-1D18A9856A87","full_name":"Prat, Tomas","last_name":"Prat"},{"last_name":"Grones","full_name":"Grones, Peter","id":"399876EC-F248-11E8-B48F-1D18A9856A87","first_name":"Peter"},{"first_name":"Danka","last_name":"Haruštiaková","full_name":"Haruštiaková, Danka"},{"first_name":"Martina","last_name":"Matonohova","full_name":"Matonohova, Martina"},{"last_name":"Spíchal","full_name":"Spíchal, Lukáš","first_name":"Lukáš"},{"first_name":"Tomasz","full_name":"Nodzyński, Tomasz","last_name":"Nodzyński"},{"first_name":"Jirí","orcid":"0000-0002-8302-7596","full_name":"Friml, Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87","last_name":"Friml"},{"full_name":"Hejátko, Jan","last_name":"Hejátko","first_name":"Jan"}],"language":[{"iso":"eng"}],"day":"01","pubrep_id":"1006","file_date_updated":"2020-07-14T12:44:47Z","status":"public","scopus_import":"1","_id":"1372","department":[{"_id":"JiFr"}],"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."}],"external_id":{"pmid":["27457979"],"isi":["000381545000002"]}},{"doi":"10.1111/nph.14019","date_published":"2016-07-01T00:00:00Z","corr_author":"1","page":"65 - 74","has_accepted_license":"1","oa_version":"Submitted Version","quality_controlled":"1","ddc":["581"],"oa":1,"month":"07","article_processing_charge":"No","title":"PIN6 auxin transporter at endoplasmic reticulum and plasma membrane mediates auxin homeostasis and organogenesis in Arabidopsis","intvolume":" 211","isi":1,"volume":211,"type":"journal_article","year":"2016","date_updated":"2025-09-18T14:23:21Z","publication_status":"published","publication":"New Phytologist","publist_id":"5790","fulldoi":"https://doi.org/10.1111/nph.14019","file":[{"file_id":"5016","file_size":3828383,"checksum":"23522ced3508ffe7a4f247c4230e6493","access_level":"open_access","date_created":"2018-12-12T10:13:32Z","date_updated":"2020-07-14T12:44:53Z","file_name":"IST-2018-1004-v1+1_Simon_NewPhytol_2016_proof.pdf","creator":"system","content_type":"application/pdf","relation":"main_file"}],"date_created":"2018-12-11T11:51:54Z","status":"public","pubrep_id":"1004","file_date_updated":"2020-07-14T12:44:53Z","day":"01","language":[{"iso":"eng"}],"author":[{"first_name":"Sibu","orcid":"0000-0002-1998-6741","last_name":"Simon","full_name":"Simon, Sibu","id":"4542EF9A-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Petr","last_name":"Skůpa","full_name":"Skůpa, Petr"},{"first_name":"Tom","last_name":"Viaene","full_name":"Viaene, Tom"},{"full_name":"Zwiewka, Marta","last_name":"Zwiewka","first_name":"Marta"},{"full_name":"Tejos, Ricardo","last_name":"Tejos","first_name":"Ricardo"},{"first_name":"Petr","full_name":"Klíma, Petr","last_name":"Klíma"},{"first_name":"Mária","full_name":"Čarná, Mária","last_name":"Čarná"},{"full_name":"Rolčík, Jakub","last_name":"Rolčík","first_name":"Jakub"},{"full_name":"De Rycke, Riet","last_name":"De Rycke","first_name":"Riet"},{"first_name":"Ignacio","full_name":"Moreno, Ignacio","last_name":"Moreno"},{"last_name":"Dobrev","full_name":"Dobrev, Petre","first_name":"Petre"},{"full_name":"Orellana, Ariel","last_name":"Orellana","first_name":"Ariel"},{"last_name":"Zažímalová","full_name":"Zažímalová, Eva","first_name":"Eva"},{"first_name":"Jirí","orcid":"0000-0002-8302-7596","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jirí","last_name":"Friml"}],"external_id":{"isi":["000379212800008"]},"abstract":[{"lang":"eng","text":"Plant development mediated by the phytohormone auxin depends on tightly controlled cellular auxin levels at its target tissue that are largely established by intercellular and intracellular auxin transport mediated by PIN auxin transporters. 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."}],"issue":"1","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publisher":"Wiley-Blackwell","citation":{"ista":"Simon S, Skůpa P, Viaene T, Zwiewka M, Tejos R, Klíma P, Čarná M, Rolčík J, De Rycke R, Moreno I, Dobrev P, Orellana A, Zažímalová E, Friml J. 2016.

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."}],"issue":"2","article_number":"e0147830","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","acknowledgement":"We thank J.

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).

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.

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.","lang":"eng"}],"external_id":{"isi":["000414797400001"]}},{"type":"journal_article","year":"2015","date_updated":"2025-09-29T11:04:05Z","publication":"Nature Plants","publication_status":"published","publist_id":"5827","date_created":"2018-12-11T11:51:42Z","fulldoi":"https://doi.org/10.1038/nplants.2015.94","intvolume":" 1","isi":1,"volume":1,"oa":1,"month":"07","article_processing_charge":"No","title":"V-ATPase activity in the TGN/EE is required for exocytosis and recycling in Arabidopsis","doi":"10.1038/nplants.2015.94","date_published":"2015-07-06T00:00:00Z","article_type":"original","oa_version":"Submitted Version","quality_controlled":"1","pmid":1,"main_file_link":[{"open_access":"1","url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4905525/"}],"publisher":"Nature Publishing Group","citation":{"ama":"Yu L, Scholl S, Doering A, et al.

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.","lang":"eng"}],"external_id":{"pmid":["27250258"],"isi":["000364407200001"]},"status":"public","day":"06","language":[{"iso":"eng"}],"author":[{"full_name":"Yu, Luo","last_name":"Yu","first_name":"Luo"},{"full_name":"Scholl, Stefan","last_name":"Scholl","first_name":"Stefan"},{"first_name":"Anett","last_name":"Doering","full_name":"Doering, Anett"},{"first_name":"Zhang","full_name":"Yi, Zhang","last_name":"Yi"},{"last_name":"Irani","full_name":"Irani, Niloufer","first_name":"Niloufer"},{"first_name":"Simone","last_name":"Di Rubbo","full_name":"Di Rubbo, Simone"},{"last_name":"Neumetzler","full_name":"Neumetzler, Lutz","first_name":"Lutz"},{"first_name":"Praveen","full_name":"Krishnamoorthy, Praveen","last_name":"Krishnamoorthy"},{"last_name":"Van Houtte","full_name":"Van Houtte, Isabelle","first_name":"Isabelle"},{"last_name":"Mylle","full_name":"Mylle, Evelien","first_name":"Evelien"},{"last_name":"Bischoff","full_name":"Bischoff, Volker","first_name":"Volker"},{"first_name":"Samantha","full_name":"Vernhettes, Samantha","last_name":"Vernhettes"},{"first_name":"Johan","full_name":"Winne, Johan","last_name":"Winne"},{"last_name":"Friml","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jirí","first_name":"Jirí","orcid":"0000-0002-8302-7596"},{"first_name":"York","last_name":"Stierhof","full_name":"Stierhof, York"},{"last_name":"Schumacher","full_name":"Schumacher, Karin","first_name":"Karin"},{"last_name":"Persson","full_name":"Persson, Staffan","first_name":"Staffan"},{"first_name":"Eugenia","full_name":"Russinova, Eugenia","last_name":"Russinova"}]},{"date_published":"2015-10-01T00:00:00Z","doi":"10.12688/f1000research.7143.1","ddc":["570"],"tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"quality_controlled":"1","oa_version":"Published Version","has_accepted_license":"1","corr_author":"1","month":"10","oa":1,"title":"Embryo-lethal phenotypes in early abp1 mutants are due to disruption of the neighboring BSM gene","article_processing_charge":"No","intvolume":" 4","volume":4,"year":"2015","type":"journal_article","date_created":"2018-12-11T11:52:26Z","fulldoi":"https://doi.org/10.12688/f1000research.7143.1","file":[{"date_updated":"2020-07-14T12:44:59Z","file_name":"IST-2016-497-v1+1_10.12688_f1000research.7143.1_20151102.pdf","date_created":"2018-12-12T10:16:12Z","access_level":"open_access","file_id":"5198","file_size":4414248,"checksum":"8beae5cbe988e1060265ae7de2ee8306","relation":"main_file","content_type":"application/pdf","creator":"system"}],"publist_id":"5668","publication":"F1000 Research ","publication_status":"published","date_updated":"2025-04-15T07:48:03Z","project":[{"grant_number":"282300","call_identifier":"FP7","name":"Polarity and subcellular dynamics in plants","_id":"25716A02-B435-11E9-9278-68D0E5697425"}],"status":"public","author":[{"last_name":"Michalko","full_name":"Michalko, Jaroslav","id":"483727CA-F248-11E8-B48F-1D18A9856A87","first_name":"Jaroslav"},{"last_name":"Dravecka","full_name":"Dravecka, Marta","id":"4342E402-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2519-8004","first_name":"Marta"},{"orcid":"0000-0003-4398-476X","first_name":"Tobias","id":"3E6DB97A-F248-11E8-B48F-1D18A9856A87","full_name":"Bollenbach, Tobias","last_name":"Bollenbach"},{"orcid":"0000-0002-8302-7596","first_name":"Jirí","last_name":"Friml","id":"4159519E-F248-11E8-B48F-1D18A9856A87","full_name":"Friml, Jirí"}],"language":[{"iso":"eng"}],"day":"01","file_date_updated":"2020-07-14T12:44:59Z","pubrep_id":"497","abstract":[{"lang":"eng","text":"The Auxin Binding Protein1 (ABP1) has been identified based on its ability to bind auxin with high affinity and studied for a long time as a prime candidate for the extracellular auxin receptor responsible for mediating in particular the fast non-transcriptional auxin responses. However, the contradiction between the embryo-lethal phenotypes of the originally described Arabidopsis T-DNA insertional knock-out alleles (abp1-1 and abp1-1s) and the wild type-like phenotypes of other recently described loss-of-function alleles (abp1-c1 and abp1-TD1) questions the biological importance of ABP1 and relevance of the previous genetic studies. Here we show that there is no hidden copy of the ABP1 gene in the Arabidopsis genome but the embryo-lethal phenotypes of abp1-1 and abp1-1s alleles are very similar to the knock-out phenotypes of the neighboring gene, BELAYA SMERT (BSM). Furthermore, the allelic complementation test between bsm and abp1 alleles shows that the embryo-lethality in the abp1-1 and abp1-1s alleles is caused by the off-target disruption of the BSM locus by the T-DNA insertions. This clarifies the controversy of different phenotypes among published abp1 knock-out alleles and asks for reflections on the developmental role of ABP1."}],"ec_funded":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"F1000 Research","_id":"1509","scopus_import":"1","department":[{"_id":"JiFr"},{"_id":"ToBo"}],"acknowledgement":"This work was supported by ERC Independent Research grant (ERC-2011-StG-20101109-PSDP to JF).

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.","lang":"eng"}],"isi":1,"volume":42,"intvolume":" 42","publication_status":"published","publication":"Functional Plant Biology","publist_id":"5639","publication_identifier":{"issn":["1445-4408"]},"fulldoi":"https://doi.org/10.1071/FP14171","date_created":"2018-12-11T11:52:34Z","date_updated":"2025-09-23T07:59:44Z","type":"journal_article","year":"2015","oa_version":"None","article_type":"original","quality_controlled":"1","pmid":1,"page":"239 - 251","date_published":"2015-03-01T00:00:00Z","doi":"10.1071/FP14171","title":"Auxin-modulated root growth inhibition in Arabidopsis thaliana seedlings with ammonium as the sole nitrogen source","article_processing_charge":"No","month":"03"}]
