--- _id: '7427' abstract: - lang: eng text: Plants, like other multicellular organisms, survive through a delicate balance between growth and defense against pathogens. Salicylic acid (SA) is a major defense signal in plants, and the perception mechanism as well as downstream signaling activating the immune response are known. Here, we identify a parallel SA signaling that mediates growth attenuation. SA directly binds to A subunits of protein phosphatase 2A (PP2A), inhibiting activity of this complex. Among PP2A targets, the PIN2 auxin transporter is hyperphosphorylated in response to SA, leading to changed activity of this important growth regulator. Accordingly, auxin transport and auxin-mediated root development, including growth, gravitropic response, and lateral root organogenesis, are inhibited. This study reveals how SA, besides activating immunity, concomitantly attenuates growth through crosstalk with the auxin distribution network. Further analysis of this dual role of SA and characterization of additional SA-regulated PP2A targets will provide further insights into mechanisms maintaining a balance between growth and defense. acknowledged_ssus: - _id: Bio - _id: LifeSc acknowledgement: "We thank Shigeyuki Betsuyaku (University of Tsukuba), Alison Delong (Brown University), Xinnian Dong (Duke University), Dolf Weijers (Wageningen University), Yuelin Zhang (UBC), and Martine Pastuglia (Institut Jean-Pierre Bourgin) for sharing published materials; Jana Riederer for help with cantharidin physiological analysis; David Domjan for help with cloning pET28a-PIN2HL; Qing Lu for help with DARTS; Hana Kozubı´kova´ for technical support on SA derivative synthesis; Zuzana Vondra´ kova´ for technical support with tobacco cells; Lucia Strader (Washington University), Bert De Rybel (Ghent University), Bartel Vanholme (Ghent University), and Lukas Mach (BOKU) for helpful discussions; and bioimaging and life science facilities of IST Austria for continuous support.

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

Plant-specific pin-formed (PIN) proteins and several phosphoglycoprotein (PGP) transporters are crucial factors in auxin transport-related development, yet the molecular function of PINs remains unknown. Here, we show that PINs mediate auxin efflux from mammalian and yeast cells without needing additional plant-specific factors. Conditional gain-of-function alleles and quantitative measurements of auxin accumulation in Arabidopsis and tobacco cultured cells revealed that the action of PINs in auxin efflux is distinct from PGP, rate-limiting, specific to auxins, and sensitive to auxin transport inhibitors. This suggests a direct involvement of PINs in catalyzing cellular auxin efflux. author: - first_name: Jan full_name: Petrášek, Jan last_name: Petrášek - first_name: Jozef full_name: Mravec, Jozef last_name: Mravec - first_name: Rodolphe full_name: Bouchard, Rodolphe last_name: Bouchard - first_name: Joshua full_name: Blakeslee, Joshua last_name: Blakeslee - first_name: Melinda F full_name: Melinda Abas id: 3CFB3B1C-F248-11E8-B48F-1D18A9856A87 last_name: Abas - first_name: Daniela full_name: Seifertová, Daniela last_name: Seifertová - first_name: Justyna full_name: Wiśniewska, Justyna last_name: Wiśniewska - first_name: Zerihun full_name: Tadele, Zerihun last_name: Tadele - first_name: Martin full_name: Kubeš, Martin last_name: Kubeš - first_name: Milada full_name: Čovanová, Milada last_name: Čovanová - first_name: Pankaj full_name: Dhonukshe, Pankaj last_name: Dhonukshe - first_name: Petr full_name: Skůpa, Petr last_name: Skůpa - first_name: Eva full_name: Eva Benková id: 38F4F166-F248-11E8-B48F-1D18A9856A87 last_name: Benková orcid: 0000-0002-8510-9739 - first_name: Lucie full_name: Perry, Lucie last_name: Perry - first_name: Pavel full_name: Křeček, Pavel last_name: Křeček - first_name: Ok full_name: Lee, Ok Ran last_name: Lee - first_name: Gerald full_name: Fink, Gerald R last_name: Fink - first_name: Markus full_name: Geisler, Markus last_name: Geisler - first_name: Angus full_name: Murphy, Angus S last_name: Murphy - first_name: Christian full_name: Luschnig, Christian last_name: Luschnig - first_name: Eva full_name: Zažímalová, Eva last_name: Zažímalová - first_name: Jirí full_name: Jirí Friml id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 citation: ama: Petrášek J, Mravec J, Bouchard R, et al.
