TWISTED DWARF1 mediates the action of auxin transport inhibitors on actin cytoskeleton dynamics

Zhu, Jinsheng ; Bailly, Aurelien ; Zwiewka, Marta ; Sovero, Valpuri ; Donato, Martin Di ; Ge, Pei ; Oehri, Jacqueline ; Aryal, Bibek ; Hao, Pengchao ; Linnert, Miriam ; Burgardt, Noelia Inés ; Lücke, Christian ; Weiwad, Matthias ; Michel, Max ; Weiergräber, Oliver H. ; Pollmann, Stephan ; Azzarello, Elisa ; Mancuso, Stefano ; Ferro, Noel ; Fukao, Yoichiro ; Hoffmann, Céline ; Wedlich-Söldner, Roland ; Friml, Jiří ; Thomas, Clément ; Geisler, Markus

Plant growth and architecture is regulated by the polar distribution of the hormone auxin. Polarity and flexibility of this process is provided by constant cycling of auxin transporter vesicles along actin filaments, coordinated by a positive auxin-actin feedback loop. Both polar auxin transport and vesicle cycling are inhibited by synthetic auxin transport inhibitors, such as...

WOX5–IAA17 feedback circuit-mediated cellular auxin response is crucial for the patterning of root stem cell niches in Arabidopsis

In plants, the patterning of stem cell-enriched meristems requires a graded auxin response maximum that emerges from the concerted action of polar auxin transport, auxin biosynthesis, auxin metabolism, and cellular auxin response machinery. However, mechanisms underlying this auxin response maximum-mediated root stem cell maintenance are not fully understood. Here, we present unexpected evidence...

Expression of TWISTED DWARF1 lacking its in-plane membrane anchor leads to increased cell elongation and hypermorphic growth

Bailly, Aurélien ; Wang, Bangjun ; Zwiewka, Marta ; Pollmann, Stephan ; Schenck, Daniel ; Lüthen, Hartwig ; Schulz, Alexander ; Friml, Jiri ; Geisler, Markus

Plant growth is achieved predominantly by cellular elongation, which is thought to be controlled on several levels by apoplastic auxin. 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...

ER-localized auxin transporter PIN8 regulates auxin homeostasis and male gametophyte development in Arabidopsis

Ding, Zhaojun ; Wang, Bangjun ; Moreno, Ignacio ; Dupláková, Nikoleta ; Simon, Sibu ; Carraro, Nicola ; Reemmer, Jesica ; Pěnčík, Aleš ; Chen, Xu ; Tejos, Ricardo ; Skůpa, Petr ; Pollmann, Stephan ; Mravec, Jozef ; Petrášek, Jan ; Zažímalová, Eva ; Honys, David ; Rolčík, Jakub ; Murphy, Angus ; Orellana, Ariel ; Geisler, Markus ; Friml, Jiří

Auxin is a key coordinative signal required for many aspects of plant development and its levels are controlled by auxin metabolism and intercellular auxin transport. Here we find that a member of PIN auxin transporter family, PIN8 is expressed in male gametophyte of Arabidopsis thaliana and has a crucial role in pollen development and functionality. Ectopic expression in sporophytic tissues...

Regulation of ABCB1/PGP1-catalysed auxin transport by linker phosphorylation

Henrichs, Sina ; Wang, Bangjun ; Fukao, Yoichiro ; Zhu, Jinsheng ; Charrier, Laurence ; Bailly, Aurélien ; Oehring, Sophie C ; Linnert, Miriam ; Weiwad, Matthias ; Endler, Anne ; Nanni, Paolo ; Pollmann, Stephan ; Mancuso, Stefano ; Schulz, Alexander ; Geisler, Markus

In: The EMBO Journal, 2012, p. -

Polar transport of the plant hormone auxin is controlled by PIN- and ABCB/PGP-efflux catalysts. PIN polarity is regulated by the AGC protein kinase, PINOID (PID), while ABCB activity was shown to be dependent on interaction with the FKBP42, TWISTED DWARF1 (TWD1). Using co-immunoprecipitation (co-IP) and shotgun LC–MS/MS analysis, we identified PID as a valid partner in the interaction with...
