--- _id: '147' abstract: - lang: eng text: The trafficking of subcellular cargos in eukaryotic cells crucially depends on vesicle budding, a process mediated by ARF-GEFs (ADP-ribosylation factor guanine nucleotide exchange factors). In plants, ARF-GEFs play essential roles in endocytosis, vacuolar trafficking, recycling, secretion, and polar trafficking. Moreover, they are important for plant development, mainly through controlling the polar subcellular localization of PIN-FORMED (PIN) transporters of the plant hormone auxin. Here, using a chemical genetics screen in Arabidopsis thaliana, we identified Endosidin 4 (ES4), an inhibitor of eukaryotic ARF-GEFs. ES4 acts similarly to and synergistically with the established ARF-GEF inhibitor Brefeldin A and has broad effects on intracellular trafficking, including endocytosis, exocytosis, and vacuolar targeting. Additionally, Arabidopsis and yeast (Sacharomyces cerevisiae) mutants defective in ARF-GEF show altered sensitivity to ES4. ES4 interferes with the activation-based membrane association of the ARF1 GTPases, but not of their mutant variants that are activated independently of ARF-GEF activity. Biochemical approaches and docking simulations confirmed that ES4 specifically targets the SEC7 domain-containing ARF-GEFs. These observations collectively identify ES4 as a chemical tool enabling the study of ARF-GEF-mediated processes, including ARF-GEF-mediated plant development. acknowledgement: We thank Gerd Jürgens, Sandra Richter, and Sheng Yang He for providing antibodies; Maciek Adamowski, Fernando Aniento, Sebastian Bednarek, Nico Callewaert, Matyás Fendrych, Elena Feraru, and Mugurel I.

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

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.

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.

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.

While PINIOD (PID) kinase is directly involved in the phosphorylation of PIN proteins, the phosphatase holoenzyme complexes that dephosphorylate PIN proteins remain elusive. Here, we demonstrate that mutations simultaneously disrupting the function of Arabidopsis thaliana FyPP1 (for Phytochrome-associated serine/threonine protein phosphatase1) and FyPP3, two homologous genes encoding the catalytic subunits of protein phosphatase6 (PP6), cause elevated accumulation of phosphorylated PIN proteins, correlating with a basal-to-apical shift in subcellular PIN localization. The changes in PIN polarity result in increased root basipetal auxin transport and severe defects, including shorter roots, fewer lateral roots, defective columella cells, root meristem collapse, abnormal cotyledons (small, cup-shaped, or fused cotyledons), and altered leaf venation. Our molecular, biochemical, and genetic data support the notion that FyPP1/3, SAL (for SAPS DOMAIN-LIKE), and PP2AA proteins (RCN1 [for ROOTS CURL IN NAPHTHYLPHTHALAMIC ACID1] or PP2AA1, PP2AA2, and PP2AA3) physically interact to form a novel PP6-type heterotrimeric holoenzyme complex. We also show that FyPP1/3, SAL, and PP2AA interact with a subset of PIN proteins and that for SAL the strength of the interaction depends on the PIN phosphorylation status. Thus, an Arabidopsis PP6-type phosphatase holoenzyme acts antagonistically with PID to direct auxin transport polarity and plant development by directly regulating PIN phosphorylation.
