--- _id: '2188' abstract: - lang: eng text: Although plant and animal cells use a similar core mechanism to deliver proteins to the plasma membrane, their different lifestyle, body organization and specific cell structures resulted in the acquisition of regulatory mechanisms that vary in the two kingdoms. In particular, cell polarity regulators do not seem to be conserved, because genes encoding key components are absent in plant genomes. In plants, the broad knowledge on polarity derives from the study of auxin transporters, the PIN-FORMED proteins, in the model plant Arabidopsis thaliana. In animals, much information is provided from the study of polarity in epithelial cells that exhibit basolateral and luminal apical polarities, separated by tight junctions. In this review, we summarize the similarities and differences of the polarization mechanisms between plants and animals and survey the main genetic approaches that have been used to characterize new genes involved in polarity establishment in plants, including the frequently used forward and reverse genetics screens as well as a novel chemical genetics approach that is expected to overcome the limitation of classical genetics methods. acknowledgement: "This work was supported by a grant from the Research Foundation-Flanders (Odysseus).\r\n\r\n" article_number: '140017' author: - first_name: Urszula full_name: Kania, Urszula id: 4AE5C486-F248-11E8-B48F-1D18A9856A87 last_name: Kania - first_name: Matyas full_name: Fendrych, Matyas last_name: Fendrych - first_name: Jiřĺ full_name: Friml, Jiřĺ id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Kania U, Fendrych M, Friml J.

The plant hormone auxin is distributed through intercellular transport and triggers various cellular responses. Auxin transporters of the PIN-FORMED (PIN) family localize asymmetrically at the plasma membrane (PM) and mediate the directional transport of auxin between cells. A fungal toxin, brefeldin A (BFA), inhibits a subset of guanine nucleotide exchange factors for ADP-ribosylation factor small GTPases (ARF GEFs) including GNOM, which plays a major role in localization of PIN1 predominantly to the basal side of the PM. The Arabidopsis genome encodes 19 ARF-related putative GTPases. However, ARF components involved in PIN1 localization have been genetically poorly defined. Using a fluorescence imaging-based forward genetic approach, we identified an Arabidopsis mutant, bfa-visualized exocytic trafficking defective1 (bex1), in which PM localization of PIN1-green fluorescent protein (GFP) as well as development is hypersensitive to BFA. We found that in bex1 a member of the ARF1 gene family, ARF1A1C, was mutated. ARF1A1C localizes to the trans-Golgi network/early endosome and Golgi apparatus, acts synergistically to BEN1/MIN7 ARF GEF and is important for PIN recycling to the PM. Consistent with the developmental importance of PIN proteins, functional interference with ARF1 resulted in an impaired auxin response gradient and various developmental defects including embryonic patterning defects and growth arrest. Our results show that ARF1A1C is essential for recycling of PIN auxin transporters and for various auxin-dependent developmental processes. author: - first_name: Hirokazu full_name: Tanaka, Hirokazu last_name: Tanaka - first_name: Tomasz full_name: Nodzyński, Tomasz last_name: Nodzyński - first_name: Saeko full_name: Kitakura, Saeko last_name: Kitakura - first_name: Mugurel full_name: Feraru, Mugurel last_name: Feraru - first_name: Michiko full_name: Sasabe, Michiko last_name: Sasabe - first_name: Tomomi full_name: Ishikawa, Tomomi last_name: Ishikawa - first_name: Jürgen full_name: Kleine Vehn, Jürgen last_name: Kleine Vehn - first_name: Tatsuo full_name: Kakimoto, Tatsuo last_name: Kakimoto - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Tanaka H, Nodzyński T, Kitakura S, et al.

To elucidate the molecular mechanisms governing vein pattern formation, we previously isolated vascular network defective (van) mutants that displayed venation discontinuities. Here, we report the phenotypic analysis of van4 mutants, and we identify and characterize the VAN4 gene. Detailed phenotypic analysis shows that van4 mutants are defective in procambium cell differentiation and subsequent vascular cell differentiation. Reduced shoot and root cell growth is observed in van4 mutants, suggesting that VAN4 function is important for cell growth and the establishment of venation continuity. Consistent with these phenotypes, the VAN4 gene is strongly expressed in vascular and meristematic cells. VAN4 encodes a putative TRS120, which is a known guanine nucleotide exchange factor (GEF) for Rab GTPase involved in regulating vesicle transport, and a known tethering factor that determines the specificity of membrane fusion. VAN4 protein localizes at the trans-Golgi network/early endosome (TGN/EE). Aberrant recycling of the auxin efflux carrier PIN proteins is observed in van4 mutants. These results suggest that VAN4-mediated exocytosis at the TGN plays important roles in plant vascular development and cell growth in shoot and root. Our identification of VAN4 as a putative TRS120 shows that Rab GTPases are crucial (in addition to ARF GTPases) for continuous vascular development, and provides further evidence for the importance of vesicle transport in leaf vascular formation. author: - first_name: Satoshi full_name: Naramoto, Satoshi last_name: Naramoto - first_name: Tomasz full_name: Nodzyński, Tomasz last_name: Nodzyński - first_name: Tomoko full_name: Dainobu, Tomoko last_name: Dainobu - first_name: Hirotomo full_name: Takatsuka, Hirotomo last_name: Takatsuka - first_name: Teruyo full_name: Okada, Teruyo last_name: Okada - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Hiroo full_name: Fukuda, Hiroo last_name: Fukuda citation: ama: Naramoto S, Nodzyński T, Dainobu T, et al.

The present study addresses the phylogenetic position of the Balkan endemic Ranunculus wettsteinii, as well as its taxonomic status and relationship with the widespread R. parnassiifolius, based on nuclear DNA (internal transcribed spacer, ITS) and plastid regions (rpl32-trnL, rps16-trnQ, trnK-matK and ycf6-psbM). Maximum parsimony and Bayesian inference analyses revealed a well-supported clade formed by accessions of R. wettsteinii. Furthermore, our phylogenetic and network analyses supported previous hypotheses of a likely allopolyploid origin for R. wettsteinii between R. montenegrinus and R. parnassiifolius, with the latter as the maternal parent. article_processing_charge: No author: - first_name: Eduardo full_name: Cires Rodriguez, Eduardo id: 2AD56A7A-F248-11E8-B48F-1D18A9856A87 last_name: Cires Rodriguez - first_name: Matthias full_name: Baltisberger, Matthias last_name: Baltisberger - first_name: Candela full_name: Cuesta, Candela id: 33A3C818-F248-11E8-B48F-1D18A9856A87 last_name: Cuesta orcid: 0000-0003-1923-2410 - first_name: Pablo full_name: Vargas, Pablo last_name: Vargas - first_name: José full_name: Prieto, José last_name: Prieto citation: ama: Cires Rodriguez E, Baltisberger M, Cuesta C, Vargas P, Prieto J.

In plants, clathrin-mediated endocytosis is essential for physiology and development, but the identification and organization of the machinery operating this process remains largely obscure. Here, we identified an eight-core-component protein complex, the TPLATE complex, essential for plant growth via its role as major adaptor module for clathrin-mediated endocytosis. This complex consists of evolutionarily unique proteins that associate closely with core endocytic elements. The TPLATE complex is recruited as dynamic foci at the plasma membrane preceding recruitment of adaptor protein complex 2, clathrin, and dynamin-related proteins. Reduced function of different complex components severely impaired internalization of assorted endocytic cargoes, demonstrating its pivotal role in clathrin-mediated endocytosis. Taken together, the TPLATE complex is an early endocytic module representing a unique evolutionary plant adaptation of the canonical eukaryotic pathway for clathrin-mediated endocytosis. author: - first_name: Astrid full_name: Gadeyne, Astrid last_name: Gadeyne - first_name: Clara full_name: Sánchez Rodríguez, Clara last_name: Sánchez Rodríguez - first_name: Steffen full_name: Vanneste, Steffen last_name: Vanneste - first_name: Simone full_name: Di Rubbo, Simone last_name: Di Rubbo - first_name: Henrik full_name: Zauber, Henrik last_name: Zauber - first_name: Kevin full_name: Vanneste, Kevin last_name: Vanneste - first_name: Jelle full_name: Van Leene, Jelle last_name: Van Leene - first_name: Nancy full_name: De Winne, Nancy last_name: De Winne - first_name: Dominique full_name: Eeckhout, Dominique last_name: Eeckhout - first_name: Geert full_name: Persiau, Geert last_name: Persiau - first_name: Eveline full_name: Van De Slijke, Eveline last_name: Van De Slijke - first_name: Bernard full_name: Cannoot, Bernard last_name: Cannoot - first_name: Leen full_name: Vercruysse, Leen last_name: Vercruysse - first_name: Jonathan full_name: Mayers, Jonathan last_name: Mayers - first_name: Maciek full_name: Adamowski, Maciek id: 45F536D2-F248-11E8-B48F-1D18A9856A87 last_name: Adamowski orcid: 0000-0001-6463-5257 - first_name: Urszula full_name: Kania, Urszula id: 4AE5C486-F248-11E8-B48F-1D18A9856A87 last_name: Kania - first_name: Matthias full_name: Ehrlich, Matthias last_name: Ehrlich - first_name: Alois full_name: Schweighofer, Alois last_name: Schweighofer - first_name: Tijs full_name: Ketelaar, Tijs last_name: Ketelaar - first_name: Steven full_name: Maere, Steven last_name: Maere - first_name: Sebastian full_name: Bednarek, Sebastian last_name: Bednarek - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Kris full_name: Gevaert, Kris last_name: Gevaert - first_name: Erwin full_name: Witters, Erwin last_name: Witters - first_name: Eugenia full_name: Russinova, Eugenia last_name: Russinova - first_name: Staffan full_name: Persson, Staffan last_name: Persson - first_name: Geert full_name: De Jaeger, Geert last_name: De Jaeger - first_name: Daniël full_name: Van Damme, Daniël last_name: Van Damme citation: ama: Gadeyne A, Sánchez Rodríguez C, Vanneste S, et al.

Plant hormones such as auxins and cytokinins are classes of compounds which are often applied exogenously. Nevertheless, plants possess a well-established machinery to regulate the active pool of exogenously applied compounds by converting them to metabolites and conjugates. Consequently, it is often very useful to know the in vivo status of applied compounds to connect them with some of the regulatory events in plant developmental processes. The in vivo status of applied compounds can be measured by incubating plants with radiolabeled compounds, followed by extraction, purification, and HPLC metabolic profiling of plant extracts. Recently we have used this method to characterize the intracellularly localized PIN protein, PIN5. Here we explain the method in detail, with a focus on general application.

Auxin export into the apoplast is achieved by plasma membrane efflux catalysts of the PIN-FORMED (PIN) and ATP-binding cassette protein subfamily B/phosphor- glycoprotein (ABCB/PGP) classes; the latter were shown to depend on interaction with the FKBP42, TWISTED DWARF1 (TWD1). Here by using a transgenic approach in combination with phenotypical, biochemical and cell biological analyses we demonstrate the importance of a putative C-terminal in-plane membrane anchor of TWD1 in the regulation of ABCB-mediated auxin transport. In contrast with dwarfed twd1 loss-of-function alleles, TWD1 gain-of-function lines that lack a putative in-plane membrane anchor (HA-TWD1-Ct) show hypermorphic plant architecture, characterized by enhanced stem length and leaf surface but reduced shoot branching. Greater hypocotyl length is the result of enhanced cell elongation that correlates with reduced polar auxin transport capacity for HA-TWD1-Ct. As a consequence, HA-TWD1-Ct displays higher hypocotyl auxin accumulation, which is shown to result in elevated auxin-induced cell elongation rates. Our data highlight the importance of C-terminal membrane anchoring for TWD1 action, which is required for specific regulation of ABCB-mediated auxin transport. These data support a model in which TWD1 controls lateral ABCB1-mediated export into the apoplast, which is required for auxin-mediated cell elongation. article_processing_charge: No article_type: original author: - first_name: Aurélien full_name: Bailly, Aurélien last_name: Bailly - first_name: Bangjun full_name: Wang, Bangjun last_name: Wang - first_name: Marta full_name: Zwiewka, Marta last_name: Zwiewka - first_name: Stephan full_name: Pollmann, Stephan last_name: Pollmann - first_name: Daniel full_name: Schenck, Daniel last_name: Schenck - first_name: Hartwig full_name: Lüthen, Hartwig last_name: Lüthen - first_name: Alexander full_name: Schulz, Alexander last_name: Schulz - 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: Bailly A, Wang B, Zwiewka M, et al.

The UPR is critical for growth and development; nonetheless, connections between the UPR and other cellular regulatory processes remain largely unknown. Here, we identify a link between the UPR and the phytohormone auxin, a master regulator of plant physiology. We show that ER stress triggers down-regulation of auxin receptors and transporters in Arabidopsis thaliana. We also demonstrate that an Arabidopsis mutant of a conserved ER stress sensor IRE1 exhibits defects in the auxin response and levels. These data not only support that the plant IRE1 is required for auxin homeostasis, they also reveal a species-specific feature of IRE1 in multicellular eukaryotes. Furthermore, by establishing that UPR activation is reduced in mutants of ER-localized auxin transporters, including PIN5, we define a long-neglected biological significance of ER-based auxin regulation. We further examine the functional relationship of IRE1 and PIN5 by showing that an ire1 pin5 triple mutant enhances defects of UPR activation and auxin homeostasis in ire1 or pin5. Our results imply that the plant UPR has evolved a hormone-dependent strategy for coordinating ER function with physiological processes. author: - first_name: Yani full_name: Chen, Yani last_name: Chen - first_name: Kyaw full_name: Aung, Kyaw last_name: Aung - first_name: Jakub full_name: Rolčík, Jakub last_name: Rolčík - first_name: Kathryn full_name: Walicki, Kathryn last_name: Walicki - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Federica full_name: Brandizzí, Federica last_name: Brandizzí citation: ama: Chen Y, Aung K, Rolčík J, Walicki K, Friml J, Brandizzí F.

The reversible phosphorylation of PPIs on the 3, 4, or 5 position of inositol is performed by a set of organelle-specific kinases and phosphatases, and the characteristic head groups make these molecules ideal for regulating biological processes in time and space. In yeast and mammals, Ptdlns3P and Ptdlns(3,5)P2 play crucial roles in trafficking toward the lytic compartments, whereas the role in plants is not yet fully understood. Here we identified the role of a land plant-specific subgroup of PPI phosphatases, the suppressor of actin 2 (SAC2) to SAC5, during vauolar trafficking and morphogenesis in Arabidopsis thaliana. SAC2-SAC5 localize to the tonoplast along with Ptdlns3P, the presumable product of their activity. in SAC gain- and loss-of-function mutants, the levels of Ptdlns monophosphates and bisphosphates were changed, with opposite effects on the morphology of storage and lytic vacuoles, and the trafficking toward the vacuoles was defective. Moreover, multiple sac knockout mutants had an increased number of smaller storage and lytic vacuoles, whereas extralarge vacuoles were observed in the overexpression lines, correlating with various growth and developmental defects. The fragmented vacuolar phenotype of sac mutants could be mimicked by treating wild-type seedlings with Ptdlns(3,5)P2, corroborating that this PPI is important for vacuole morphology. Taken together, these results provide evidence that PPIs, together with their metabolic enzymes SAC2-SAC5, are crucial for vacuolar trafficking and for vacuolar morphology and function in plants. alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Petra full_name: Marhavá, Petra id: 44E59624-F248-11E8-B48F-1D18A9856A87 last_name: Marhavá citation: ama: Marhavá P.

Plants cope with these by a remarkable developmental flexibility, which is embedded in their strategy to survive. Plants can adjust their size, shape and number of organs, bend according to gravity and light, and regenerate tissues that were damaged, utilizing a coordinating, intercellular signal, the plant hormone, auxin. Another versatile signal is the cation, Ca2+, which is a crucial second messenger for many rapid cellular processes during responses to a wide range of endogenous and environmental signals, such as hormones, light, drought stress and others. Auxin is a good candidate for one of these Ca2+-activating signals. However, the role of auxin-induced Ca2+ signaling is poorly understood. Here, we will provide an overview of possible developmental and physiological roles, as well as mechanisms underlying the interconnection of Ca2+ and auxin signaling.

Auxin-mediated growth regulation typically involves the establishment of an auxin concentration gradient mediated by polarly localized auxin transporters. The localization of auxin carriers and their amount at the plasma membrane are controlled by membrane trafficking processes such as secretion, endocytosis, and recycling. In contrast to endocytosis or recycling, how the secretory pathway mediates the localization of auxin carriers is not well understood. In this study we have used the differential cell elongation process during apical hook development to elucidate the mechanisms underlying the post-Golgi trafficking of auxin carriers in Arabidopsis. We show that differential cell elongation during apical hook development is defective in Arabidopsis mutant echidna (ech). ECH protein is required for the trans-Golgi network (TGN)-mediated trafficking of the auxin influx carrier AUX1 to the plasma membrane. In contrast, ech mutation only marginally perturbs the trafficking of the highly related auxin influx carrier LIKE-AUX1-3 or the auxin efflux carrier PIN-FORMED-3, both also involved in hook development. Electron tomography reveals that the trafficking defects in ech mutant are associated with the perturbation of secretory vesicle genesis from the TGN. Our results identify differential mechanisms for the post-Golgi trafficking of de novo-synthesized auxin carriers to plasma membrane from the TGN and reveal how trafficking of auxin influx carriers mediates the control of differential cell elongation in apical hook development. author: - first_name: Yohann full_name: Boutté, Yohann last_name: Boutté - first_name: Kristoffer full_name: Jonsson, Kristoffer last_name: Jonsson - first_name: Heather full_name: Mcfarlane, Heather last_name: Mcfarlane - first_name: Errin full_name: Johnson, Errin last_name: Johnson - first_name: Delphine full_name: Gendre, Delphine last_name: Gendre - first_name: Ranjan full_name: Swarup, Ranjan last_name: Swarup - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Lacey full_name: Samuels, Lacey last_name: Samuels - first_name: Stéphanie full_name: Robert, Stéphanie last_name: Robert - first_name: Rishikesh full_name: Bhalerao, Rishikesh last_name: Bhalerao citation: ama: Boutté Y, Jonsson K, Mcfarlane H, et al.

Despite the wide use of several auxin analogues in research and agriculture, little is known about the specificity of different auxin-related transport and signalling processes towards these compounds. Using seedlings of Arabidopsis thaliana and suspension-cultured cells of Nicotiana tabacum (BY-2), the physiological activity of several auxin analogues was investigated, together with their capacity to induce auxin-dependent gene expression, to inhibit endocytosis and to be transported across the plasma membrane. This study shows that the specificity criteria for different auxin-related processes vary widely. Notably, the special behaviour of some synthetic auxin analogues suggests that they might be useful tools in investigations of the molecular mechanism of auxin action. Thus, due to their differential stimulatory effects on DR5 expression, indole-3-propionic (IPA) and 2,4,5-trichlorophenoxy acetic (2,4,5-T) acids can serve in studies of TRANSPORT INHIBITOR RESPONSE 1/AUXIN SIGNALLING F-BOX (TIR1/AFB)-mediated auxin signalling, and 5-fluoroindole-3-acetic acid (5-F-IAA) can help to discriminate between transcriptional and non-transcriptional pathways of auxin signalling. The results demonstrate that the major determinants for the auxin-like physiological potential of a particular compound are very complex and involve its chemical and metabolic stability, its ability to distribute in tissues in a polar manner and its activity towards auxin signalling machinery. acknowledgement: The authors thank Dr Christian Luschnig (University of Natural Resources and Life Sciences (BOKU), Vienna, Austria) for the anti-PIN2 antibody, Professor Mark Estelle (University of California, San Diego, CA, USA) for tir1-1 mutant seeds and, last but not least, to Dr David Morris for critical reading of the manuscript.

The protein and lipid homeostasis depends on coordinated delivery of de novo synthesized or recycled cargoes to the plasma membrane by exocytosis and their subsequent removal by rerouting them for recycling or degradation. Here, we report the characterization of protein affected trafficking 3 (pat3) mutant that we identified by an epifluorescence-based forward genetic screen for mutants defective in subcellular distribution of Arabidopsis auxin transporter PIN1–GFP. While pat3 displays largely normal plant morphology and development in nutrient-rich conditions, it shows strong ectopic intracellular accumulations of different plasma membrane cargoes in structures that resemble prevacuolar compartments (PVC) with an aberrant morphology. Genetic mapping revealed that pat3 is defective in vacuolar protein sorting 35A (VPS35A), a putative subunit of the retromer complex that mediates retrograde trafficking between the PVC and trans-Golgi network. Similarly, a mutant defective in another retromer subunit, vps29, shows comparable subcellular defects in PVC morphology and protein accumulation. Thus, our data provide evidence that the retromer components VPS35A and VPS29 are essential for normal PVC morphology and normal trafficking of plasma membrane proteins in plants. In addition, we show that, out of the three VPS35 retromer subunits present in Arabidopsis thaliana genome, the VPS35 homolog A plays a prevailing role in trafficking to the lytic vacuole, presenting another level of complexity in the retromer-dependent vacuolar sorting.

The Arabidopsis PIN protein family has been shown to play important roles in developmental processes such as embryogenesis, organogenesis, vascular tissue differentiation, root meristem patterning and tropic growth. Here we analyzed roles of the less characterised Arabidopsis PIN6 auxin transporter. PIN6 is auxin-inducible and is expressed during multiple auxin-regulated developmental processes. Loss of pin6 function interfered with primary root growth and lateral root development. Misexpression of PIN6 affected auxin transport and interfered with auxin homeostasis in other growth processes such as shoot apical dominance, lateral root primordia development, adventitious root formation, root hair outgrowth and root waving. These changes in auxin-regulated growth correlated with a reduction in total auxin transport as well as with an altered activity of DR5-GUS auxin response reporter. Overall, the data indicate that PIN6 regulates auxin homeostasis during plant development. article_number: e70069 author: - first_name: Christopher full_name: Cazzonelli, Christopher last_name: Cazzonelli - first_name: Marleen full_name: Vanstraelen, Marleen last_name: Vanstraelen - first_name: Sibu full_name: Simon, Sibu id: 4542EF9A-F248-11E8-B48F-1D18A9856A87 last_name: Simon orcid: 0000-0002-1998-6741 - first_name: Kuide full_name: Yin, Kuide last_name: Yin - first_name: Ashley full_name: Carron Arthur, Ashley last_name: Carron Arthur - first_name: Nazia full_name: Nisar, Nazia last_name: Nisar - first_name: Gauri full_name: Tarle, Gauri last_name: Tarle - first_name: Abby full_name: Cuttriss, Abby last_name: Cuttriss - first_name: Iain full_name: Searle, Iain last_name: Searle - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 - first_name: Ulrike full_name: Mathesius, Ulrike last_name: Mathesius - first_name: Josette full_name: Masle, Josette last_name: Masle - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Barry full_name: Pogson, Barry last_name: Pogson citation: ama: Cazzonelli C, Vanstraelen M, Simon S, et al.

ABP1 has been shown to be involved in auxin-dependent regulation of cell division and expansion, in plasma-membrane-related processes such as changes in transmembrane potential, and in the regulation of clathrin-dependent endocytosis. However, the ABP1-regulated downstream pathway remains elusive.Methodology/Principal Findings:Using auxin transport assays and quantitative analysis of cellular morphology we show that ABP1 regulates auxin efflux from tobacco BY-2 cells. The overexpression of ABP1can counterbalance increased auxin efflux and auxin starvation phenotypes caused by the overexpression of PIN auxin efflux carrier. Relevant mechanism involves the ABP1-controlled vesicle trafficking processes, including positive regulation of endocytosis of PIN auxin efflux carriers, as indicated by fluorescence recovery after photobleaching (FRAP) and pharmacological manipulations.Conclusions/Significance:The findings indicate the involvement of ABP1 in control of rate of auxin transport across plasma membrane emphasizing the role of ABP1 in regulation of PIN activity at the plasma membrane, and highlighting the relevance of ABP1 for the formation of developmentally important, PIN-dependent auxin gradients. article_number: e70050 author: - first_name: Milada full_name: Čovanová, Milada last_name: Čovanová - first_name: Michael full_name: Sauer, Michael last_name: Sauer - first_name: Jan full_name: Rychtář, Jan last_name: Rychtář - 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: Petrášek, Jan last_name: Petrášek - first_name: Eva full_name: Zažímalová, Eva last_name: Zažímalová citation: ama: Čovanová M, Sauer M, Rychtář J, Friml J, Petrášek J, Zažímalová E.

This has allowed us to define discrete stages of organ morphogenesis and to show that reproductive organ development in P. patens is highly organized and that organ phyllotaxis differs between vegetative and reproductive development. Using the PpSHI1 and PpSHI2 reporter and knockout lines, the auxin reporters GmGH3pro:GUS and PpPINApro:GFP-GUS, and the auxin-conjugating transgene PpSHI2pro:IAAL, we could show that the PpSHI genes, and by inference also auxin, play important roles for reproductive organ development in moss. The PpSHI genes are required for the apical opening of the reproductive organs, the final differentiation of the egg cell, and the progression of canal cells into a cell death program. The apical cells of the archegonium, the canal cells, and the egg cell are also sites of auxin responsiveness and are affected by reduced levels of active auxin, suggesting that auxin mediates PpSHI function in the reproductive organs. author: - first_name: Katarina full_name: Landberg, Katarina last_name: Landberg - first_name: Eric full_name: Pederson, Eric last_name: Pederson - first_name: Tom full_name: Viaene, Tom last_name: Viaene - first_name: Behruz full_name: Bozorg, Behruz last_name: Bozorg - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Henrik full_name: Jönsson, Henrik last_name: Jönsson - first_name: Mattias full_name: Thelander, Mattias last_name: Thelander - first_name: Eva full_name: Sundberg, Eva last_name: Sundberg citation: ama: Landberg K, Pederson E, Viaene T, et al.

Cellular auxin efflux, the rate-limiting step in this process, has been shown to rely on the coordinated action of PIN-formed (PIN) and B-type ATP binding cassette (ABCB) carriers. Here, we report that polar auxin transport in the Arabidopsis thaliana root also requires the action of a Major Facilitator Superfamily (MFS) transporter, Zinc-Induced Facilitator-Like 1 (ZIFL1). Sequencing, promoter-reporter, and fluorescent protein fusion experiments indicate that the full-length ZIFL1.1 protein and a truncated splice isoform, ZIFL1.3, localize to the tonoplast of root cells and the plasma membrane of leaf stomatal guard cells, respectively. Using reverse genetics, we show that the ZIFL1.1 transporter regulates various root auxin-related processes, while the ZIFL1.3 isoform mediates drought tolerance by regulating stomatal closure. Auxin transport and immunolocalization assays demonstrate that ZIFL1.1 indirectly modulates cellular auxin efflux during shootward auxin transport at the root tip, likely by regulating plasma membrane PIN2 abundance. Finally, heterologous expression in yeast revealed that ZIFL1.1 and ZIFL1.3 share H+-coupled K+ transport activity. Thus, by determining the subcellular and tissue distribution of two isoforms, alternative splicing dictates a dual function for the ZIFL1 transporter. We propose that this MFS carrier regulates stomatal movements and polar auxin transport by modulating potassium and proton fluxes in Arabidopsis cells. author: - first_name: Estelle full_name: Remy, Estelle last_name: Remy - first_name: Tânia full_name: Cabrito, Tânia last_name: Cabrito - first_name: Pawel full_name: Baster, Pawel id: 3028BD74-F248-11E8-B48F-1D18A9856A87 last_name: Baster - first_name: Rita full_name: Batista, Rita last_name: Batista - first_name: Miguel full_name: Teixeira, Miguel last_name: Teixeira - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Isabel full_name: Sá Correia, Isabel last_name: Sá Correia - first_name: Paula full_name: Duque, Paula last_name: Duque citation: ama: Remy E, Cabrito T, Baster P, et al.

Salicylic acid (SA) is an important plant hormone that is traditionally associated with pathogen defense. Here, we describe an unanticipated effect of SA on subcellular endocytic cycling of proteins. Both exogenous treatments and endogenously enhanced SA levels repressed endocytosis of different PM proteins. The SA effect on endocytosis did not involve transcription or known components of the SA signaling pathway for transcriptional regulation. SA likely targets an endocytic mechanism that involves the coat protein clathrin, because SA interfered with the clathrin incidence at the PM and clathrin-deficient mutants were less sensitive to the impact of SA on the auxin distribution and root bending during the gravitropic response. By contrast, SA did not affect the ligand-induced endocytosis of the FLAGELLIN SENSING2 (FLS2) receptor during pathogen responses. Our data suggest that the established SA impact on transcription in plant immunity and the nontranscriptional effect of SA on clathrin-mediated endocytosis are independent mechanisms by which SA regulates distinct aspects of plant physiology. author: - first_name: Yunlong full_name: Du, Yunlong last_name: Du - first_name: Ricardo full_name: Tejos, Ricardo last_name: Tejos - first_name: Martina full_name: Beck, Martina last_name: Beck - first_name: Ellie full_name: Himschoot, Ellie last_name: Himschoot - first_name: Hongjiang full_name: Li, Hongjiang id: 33CA54A6-F248-11E8-B48F-1D18A9856A87 last_name: Li orcid: 0000-0001-5039-9660 - first_name: Silke full_name: Robatzek, Silke last_name: Robatzek - first_name: Steffen full_name: Vanneste, Steffen last_name: Vanneste - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Du Y, Tejos R, Beck M, et al.

PIN localization is under extensive control by environmental or developmental cues, but mechanisms regulating PIN localization are not fully understood. Here we show that early endosomal components ARF GEF BEN1 and newly identified Sec1/Munc18 family protein BEN2 are involved in distinct steps of early endosomal trafficking. BEN1 and BEN2 are collectively required for polar PIN localization, for their dynamic repolarization, and consequently for auxin activity gradient formation and auxin-related developmental processes including embryonic patterning, organogenesis, and vasculature venation patterning. These results show that early endosomal trafficking is crucial for cell polarity and auxin-dependent regulation of plant architecture. article_number: e1003540 author: - first_name: Hirokazu full_name: Tanaka, Hirokazu last_name: Tanaka - first_name: Saeko full_name: Kitakura, Saeko last_name: Kitakura - first_name: Hana full_name: Rakusová, Hana last_name: Rakusová - first_name: Tomohiro full_name: Uemura, Tomohiro last_name: Uemura - first_name: Mugurel full_name: Feraru, Mugurel last_name: Feraru - first_name: Riet full_name: De Rycke, Riet last_name: De Rycke - first_name: Stéphanie full_name: Robert, Stéphanie last_name: Robert - first_name: Tatsuo full_name: Kakimoto, Tatsuo last_name: Kakimoto - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Tanaka H, Kitakura S, Rakusová H, et al.

To identify new genes involved in auxin activity, a genetic screen was performed for Arabidopsis (Arabidopsis thaliana) mutants with altered expression of the auxin-responsive reporter DR5rev:GFP. One of the mutants recovered in the screen, designated as weak auxin response3 (wxr3), exhibits much lower DR5rev:GFP expression when treated with the synthetic auxin 2,4-dichlorophenoxyacetic acid and displays severe defects in root development. The wxr3 mutant decreases polar auxin transport and results in a disruption of the asymmetric auxin distribution. The levels of the auxin transporters AUXIN1 and PIN-FORMED are dramatically reduced in the wxr3 root tip. Molecular analyses demonstrate that WXR3 is ROOT ULTRAVIOLET B-SENSITIVE1 (RUS1), a member of the conserved Domain of Unknown Function647 protein family found in diverse eukaryotic organisms. Our data suggest that RUS1/WXR3 plays an essential role in the regulation of polar auxin transport by maintaining the proper level of auxin transporters on the plasma membrane. author: - first_name: Hong full_name: Yu, Hong last_name: Yu - first_name: Michael full_name: Karampelias, Michael last_name: Karampelias - first_name: Stéphanie full_name: Robert, Stéphanie last_name: Robert - first_name: Wendy full_name: Peer, Wendy last_name: Peer - first_name: Ranjan full_name: Swarup, Ranjan last_name: Swarup - first_name: Songqing full_name: Ye, Songqing last_name: Ye - first_name: Lei full_name: Ge, Lei last_name: Ge - first_name: Jerry full_name: Cohen, Jerry last_name: Cohen - first_name: Angus full_name: Murphy, Angus last_name: Murphy - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Mark full_name: Estelle, Mark last_name: Estelle citation: ama: Yu H, Karampelias M, Robert S, et al.

Whereas mechanisms of positive and negative orthogravitropism of primary roots and shoots are relatively well understood [1-3], lateral organs often show more complex growth behavior [4]. Lateral roots (LRs) seemingly suppress positive gravitropic growth and show a defined gravitropic set-point angle (GSA) that allows radial expansion of the root system (plagiotropism) [3, 4]. Despite its eminent importance for root architecture, it so far remains completely unknown how lateral organs partially suppress positive orthogravitropism. Here we show that the phytohormone auxin steers GSA formation and limits positive orthogravitropism in LR. Low and high auxin levels/signaling lead to radial or axial root systems, respectively. At a cellular level, it is the auxin transport-dependent regulation of asymmetric growth in the elongation zone that determines GSA. Our data suggest that strong repression of PIN4/PIN7 and transient PIN3 expression limit auxin redistribution in young LR columella cells. We conclude that PIN activity, by temporally limiting the asymmetric auxin fluxes in the tip of LRs, induces transient, differential growth responses in the elongation zone and, consequently, controls root architecture. author: - first_name: Michel full_name: Rosquete, Michel last_name: Rosquete - 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: Peter full_name: Marhavy, Peter id: 3F45B078-F248-11E8-B48F-1D18A9856A87 last_name: Marhavy orcid: 0000-0001-5227-5741 - first_name: Elke full_name: Barbez, Elke last_name: Barbez - first_name: Ernst full_name: Stelzer, Ernst last_name: Stelzer - first_name: Eva full_name: Benková, Eva id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 - first_name: Alexis full_name: Maizel, Alexis last_name: Maizel - first_name: Jürgen full_name: Kleine Vehn, Jürgen last_name: Kleine Vehn citation: ama: Rosquete M, von Wangenheim D, Marhavý P, et al.

The latter were shown to require the functionality of the FK506 binding protein42 TWISTED DWARF1 (TWD1), although underlying mechanisms are unclear. By genetic manipulation of TWD1 expression, we show here that TWD1 affects shootward root auxin reflux and, thus, downstream developmental traits, such as epidermal twisting and gravitropism of the root. Using immunological assays, we demonstrate a predominant lateral, mainly outward-facing, plasma membrane location for TWD1 in the root epidermis characterized by the lateral marker ABC transporter G36/PLEIOTROPIC DRUG-RESISTANCE8/PENETRATION3. At these epidermal plasma membrane domains, TWD1 colocalizes with nonpolar ABCB1. In planta bioluminescence resonance energy transfer analysis was used to verify specific ABC transporter B1 (ABCB1)-TWD1 interaction. Our data support a model in which TWD1 promotes lateral ABCB-mediated auxin efflux via protein-protein interaction at the plasma membrane, minimizing reflux from the root apoplast into the cytoplasm. acknowledgement: We would thank Vincent Vincenzetti and Laurence Charrier for excellent technical assistance, A. von Arnim for the donation of BRET vectors, E.

Here, we show that also another plant hormone, gibberellic acid (GA), shows asymmetric action during gravitropic responses. Immunodetection using an antibody against GA and monitoring GA signaling output by downstream degradation of DELLA proteins revealed an asymmetric GA distribution and response with the maximum at the lower side of gravistimulated roots. Genetic or pharmacological manipulation of GA levels or response affects gravity-mediated auxin redistribution and root bending response. The higher GA levels at the lower side of the root correlate with increased amounts of PIN-FORMED2 (PIN2) auxin transporter at the plasma membrane. The observed increase in PIN2 stability is caused by a specific GA effect on trafficking of PIN proteins to lytic vacuoles that presumably occurs downstream of brefeldin A-sensitive endosomes. Our results suggest that asymmetric auxin distribution instructive for gravity-induced differential growth is consolidated by the asymmetric action of GA that stabilizes the PIN-dependent auxin stream along the lower side of gravistimulated roots. author: - first_name: Christian full_name: Löfke, Christian last_name: Löfke - first_name: Marta full_name: Zwiewka, Marta last_name: Zwiewka - first_name: Ingo full_name: Heilmann, Ingo last_name: Heilmann - first_name: Marc full_name: Van Montagu, Marc last_name: Van Montagu - first_name: Thomas full_name: Teichmann, Thomas last_name: Teichmann - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Löfke C, Zwiewka M, Heilmann I, Van Montagu M, Teichmann T, Friml J.

Gravitropic root curvature involves coordinated and asymmetric cell elongation between the lower and upper side of the root, mediated by differential cellular auxin levels. The asymmetry in the auxin distribution is established and maintained by a spatio-temporal regulation of the PIN-FORMED (PIN) auxin transporter activity. We provide novel insights into the complex regulation of PIN abundance and activity during root gravitropism. We show that PIN2 turnover is differentially regulated on the upper and lower side of gravistimulated roots by distinct but partially overlapping auxin feedback mechanisms. In addition to regulating transcription and clathrin-mediated internalization, auxin also controls PIN abundance at the plasma membrane by promoting their vacuolar targeting and degradation. This effect of elevated auxin levels requires the activity of SKP-Cullin-F-box TIR1/AFB (SCF TIR1/AFB)-dependent pathway. Importantly, also suboptimal auxin levels mediate PIN degradation utilizing the same signalling pathway. These feedback mechanisms are functionally important during gravitropic response and ensure fine-tuning of auxin fluxes for maintaining as well as terminating asymmetric growth. author: - first_name: Pawel full_name: Baster, Pawel id: 3028BD74-F248-11E8-B48F-1D18A9856A87 last_name: Baster - first_name: Stéphanie full_name: Robert, Stéphanie last_name: Robert - first_name: Jürgen full_name: Kleine Vehn, Jürgen last_name: Kleine Vehn - first_name: Steffen full_name: Vanneste, Steffen last_name: Vanneste - first_name: Urszula full_name: Kania, Urszula id: 4AE5C486-F248-11E8-B48F-1D18A9856A87 last_name: Kania - first_name: Wim full_name: Grunewald, Wim last_name: Grunewald - first_name: Bert full_name: De Rybel, Bert last_name: De Rybel - first_name: Tom full_name: Beeckman, Tom last_name: Beeckman - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Baster P, Robert S, Kleine Vehn J, et al.

Despite the importance of this process, the machinery that regulates CME in plants is largely unknown. In mammals, the heterotetrameric ADAPTOR PROTEIN COMPLEX-2 (AP-2) is required for the formation of clathrin-coated vesicles at the plasma membrane (PM). Although the existence of AP-2 has been predicted in Arabidopsis thaliana, the biochemistry and functionality of the complex is still uncharacterized. Here, we identified all the subunits of the Arabidopsis AP-2 by tandem affinity purification and found that one of the large AP-2 subunits, AP2A1, localized at the PM and interacted with clathrin. Furthermore, endocytosis of the leucine-rich repeat receptor kinase, BRASSINOSTEROID INSENSITIVE1 (BRI1), was shown to depend on AP-2. Knockdown of the two Arabidopsis AP2A genes or overexpression of a dominant-negative version of the medium AP-2 subunit, AP2M, impaired BRI1 endocytosis and enhanced the brassinosteroid signaling. Our data reveal that the CME machinery in Arabidopsis is evolutionarily conserved and that AP-2 functions in receptormediated endocytosis.

However, it remains elusive as to how this coordination occurs during reproduction. Here, we present evidence that endocytosis, involving heterotetrameric adaptor protein complex 2 (AP-2), plays a crucial role in fertilization. An Arabidopsis thaliana mutant ap2m displays multiple defects in pollen production and viability, as well as elongation of staminal filaments and pollen tubes, all of which are pivotal processes needed for fertilization. Of these abnormalities, the defects in elongation of staminal filaments and pollen tubes were partially rescued by exogenous auxin. Moreover, DR5rev:GFP (for green fluorescent protein) expression was greatly reduced in filaments and anthers in ap2m mutant plants. At the cellular level, ap2m mutants displayed defects in both endocytosis of N-(3-triethylammonium-propyl)-4- (4-diethylaminophenylhexatrienyl) pyridinium dibromide, a lypophilic dye used as an endocytosis marker, and polar localization of auxin-efflux carrier PIN FORMED2 (PIN2) in the stamen filaments. Moreover, these defects were phenocopied by treatment with Tyrphostin A23, an inhibitor of endocytosis. Based on these results, we propose that AP-2-dependent endocytosis plays a crucial role in coordinating the multiple developmental aspects of male reproductive organs by modulating cellular auxin level through the regulation of the amount and polarity of PINs. author: - first_name: Soo full_name: Kim, Soo last_name: Kim - first_name: Zheng full_name: Xu, Zheng last_name: Xu - first_name: Kyungyoung full_name: Song, Kyungyoung last_name: Song - first_name: Dae full_name: Kim, Dae last_name: Kim - first_name: Hyangju full_name: Kang, Hyangju last_name: Kang - first_name: Ilka full_name: Reichardt, Ilka last_name: Reichardt - first_name: Eun full_name: Sohn, Eun last_name: Sohn - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Gerd full_name: Juergens, Gerd last_name: Juergens - first_name: Inhwan full_name: Hwang, Inhwan last_name: Hwang citation: ama: Kim S, Xu Z, Song K, et al.

Its nonuniform distribution between cells and tissues underlies the spatiotemporal coordination of many developmental events and responses to environmental stimuli. The regulation of auxin gradients and the formation of auxin maxima/minima most likely involve the regulation of both metabolic and transport processes. In this article, we have demonstrated that 2-oxindole-3-acetic acid (oxIAA) is a major primary IAA catabolite formed in Arabidopsis thaliana root tissues. OxIAA had little biological activity and was formed rapidly and irreversibly in response to increases in auxin levels. We further showed that there is cell type-specific regulation of oxIAA levels in the Arabidopsis root apex. We propose that oxIAA is an important element in the regulation of output from auxin gradients and, therefore, in the regulation of auxin homeostasis and response mechanisms. author: - first_name: Aleš full_name: Pěnčík, Aleš last_name: Pěnčík - first_name: Biljana full_name: Simonovik, Biljana last_name: Simonovik - first_name: Sara full_name: Petersson, Sara last_name: Petersson - first_name: Eva full_name: Henyková, Eva last_name: Henyková - first_name: Sibu full_name: Simon, Sibu id: 4542EF9A-F248-11E8-B48F-1D18A9856A87 last_name: Simon orcid: 0000-0002-1998-6741 - first_name: Kathleen full_name: Greenham, Kathleen last_name: Greenham - first_name: Yi full_name: Zhang, Yi last_name: Zhang - first_name: Mariusz full_name: Kowalczyk, Mariusz last_name: Kowalczyk - first_name: Mark full_name: Estelle, Mark last_name: Estelle - first_name: Eva full_name: Zažímalová, Eva last_name: Zažímalová - first_name: Ondřej full_name: Novák, Ondřej last_name: Novák - first_name: Göran full_name: Sandberg, Göran last_name: Sandberg - first_name: Karin full_name: Ljung, Karin last_name: Ljung citation: ama: Pěnčík A, Simonovik B, Petersson S, et al.

However, little is known about how auxin is interpreted by individual cell types. We performed a transcriptomic analysis of responses to auxin within four distinct tissues of the Arabidopsis thaliana root and demonstrate that different cell types show competence for discrete responses. The majority of auxin‐responsive genes displayed a spatial bias in their induction or repression. The novel data set was used to examine how auxin influences tissue‐specific transcriptional regulation of cell‐identity markers. Additionally, the data were used in combination with spatial expression maps of the root to plot a transcriptomic auxin‐response gradient across the apical and basal meristem. The readout revealed a strong correlation for thousands of genes between the relative response to auxin and expression along the longitudinal axis of the root. This data set and comparative analysis provide a transcriptome‐level spatial breakdown of the response to auxin within an organ where this hormone mediates many aspects of development. article_number: '688' article_processing_charge: No author: - first_name: Bastiaan full_name: Bargmann, Bastiaan last_name: Bargmann - first_name: Steffen full_name: Vanneste, Steffen last_name: Vanneste - first_name: Gabriel full_name: Krouk, Gabriel last_name: Krouk - first_name: Tal full_name: Nawy, Tal last_name: Nawy - first_name: Idan full_name: Efroni, Idan last_name: Efroni - first_name: Eilon full_name: Shani, Eilon last_name: Shani - first_name: Goh full_name: Choe, Goh last_name: Choe - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Dominique full_name: Bergmann, Dominique last_name: Bergmann - first_name: Mark full_name: Estelle, Mark last_name: Estelle - first_name: Kenneth full_name: Birnbaum, Kenneth last_name: Birnbaum citation: ama: Bargmann B, Vanneste S, Krouk G, et al.

Plants utilize directional, cell-to-cell transport of the growth hormone auxin [1, 2] to generate an asymmetric auxin response that specifies the embryonic apical-basal axis [3-6]. The auxin flow directionality depends on the polarized subcellular localization of PIN-FORMED (PIN) auxin transporters [7, 8]. It remains unknown which mechanisms and spatial cues guide cell polarization and axis orientation in early embryos. Herein, we provide conceptually novel insights into the formation of embryonic axis in Arabidopsis by identifying a crucial role of localized tryptophan-dependent auxin biosynthesis [9-12]. Local auxin production at the base of young embryos and the accompanying PIN7-mediated auxin flow toward the proembryo are required for the apical auxin response maximum and the specification of apical embryonic structures. Later in embryogenesis, the precisely timed onset of localized apical auxin biosynthesis mediates PIN1 polarization, basal auxin response maximum, and specification of the root pole. Thus, the tight spatiotemporal control of distinct local auxin sources provides a necessary, non-cell-autonomous trigger for the coordinated cell polarization and subsequent apical-basal axis orientation during embryogenesis and, presumably, also for other polarization events during postembryonic plant life [13, 14]. author: - first_name: Hélène full_name: Robert, Hélène last_name: Robert - first_name: Peter full_name: Grones, Peter id: 399876EC-F248-11E8-B48F-1D18A9856A87 last_name: Grones - first_name: Anna full_name: Stepanova, Anna last_name: Stepanova - first_name: Linda full_name: Robles, Linda last_name: Robles - first_name: Annemarie full_name: Lokerse, Annemarie last_name: Lokerse - first_name: Jose full_name: Alonso, Jose last_name: Alonso - first_name: Dolf full_name: Weijers, Dolf last_name: Weijers - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Robert H, Grones P, Stepanova A, et al.

To establish a polarized embryonic axis, plants evolved a unique mechanism that involves directional, cell-to-cell transport of the growth regulator auxin. Auxin transport relies on PIN auxin transporters [1], whose polar subcellular localization determines the flow directionality. PIN-mediated auxin transport mediates the spatial and temporal activity of the auxin response machinery [2-7] that contributes to embryo patterning processes, including establishment of the apical (shoot) and basal (root) embryo poles [8]. However, little is known of upstream mechanisms guiding the (re)polarization of auxin fluxes during embryogenesis [9]. Here, we developed a model of plant embryogenesis that correctly generates emergent cell polarities and auxin-mediated sequential initiation of apical-basal axis of plant embryo. The model relies on two precisely localized auxin sources and a feedback between auxin and the polar, subcellular PIN transporter localization. Simulations reproduced PIN polarity and auxin distribution, as well as previously unknown polarization events during early embryogenesis. The spectrum of validated model predictions suggests that our model corresponds to a minimal mechanistic framework for initiation and orientation of the apical-basal axis to guide both embryonic and postembryonic plant development. author: - first_name: Krzysztof T full_name: Wabnik, Krzysztof T id: 4DE369A4-F248-11E8-B48F-1D18A9856A87 last_name: Wabnik orcid: 0000-0001-7263-0560 - first_name: Hélène full_name: Robert, Hélène last_name: Robert - first_name: Richard full_name: Smith, Richard last_name: Smith - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Wabnik KT, Robert H, Smith R, Friml J.

We recently reported that, in the context of strong auxin flows, activity of the vacuolar ZIFL1.1 transporter is required for fine-tuning of polar auxin transport rates in the Arabidopsis root. In particular, ZIFL1.1 function protects plasma-membrane stability of the PIN2 carrier in epidermal root tip cells under conditions normally triggering PIN2 degradation. Here, we show that ZIFL1.1 activity at the root tip also promotes PIN1 plasma-membrane abundance in central cylinder cells, thus supporting the notion that ZIFL1.1 acts as a general positive modulator of polar auxin transport in roots. article_number: e25688 article_processing_charge: No article_type: original author: - first_name: Estelle full_name: Remy, Estelle last_name: Remy - first_name: Pawel full_name: Baster, Pawel id: 3028BD74-F248-11E8-B48F-1D18A9856A87 last_name: Baster - first_name: Jirí full_name: Friml, Jirí id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Paula full_name: Duque, Paula last_name: Duque citation: ama: Remy E, Baster P, Friml J, Duque P.
