Flavonol-induced changes in PIN2 polarity and auxin transport in the Arabidopsis thaliana rol1-2 mutant require phosphatase activity

Kuhn, Benjamin M. ; Nodzyński, Tomasz ; Errafi, Sanae ; Bucher, Rahel ; Gupta, Shibu ; Aryal, Bibek ; Dobrev, Petre ; Bigler, Laurent ; Geisler, Markus ; Zažímalová, Eva ; Friml, Jiří ; Ringli, Christoph

The phytohormone auxin is a major determinant and regulatory component important for plant development. Auxin transport between cells is mediated by a complex system of transporters such as AUX1/LAX, PIN, and ABCB proteins, and their localization and activity is thought to be influenced by phosphatases and kinases. Flavonols have been shown to alter auxin transport activity and changes in...

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...

The novel elicitor AsES triggers a defense response against Botrytis cinerea in Arabidopsis thaliana

Hael-Conrad, V. ; Abou-Mansour, Eliane ; Díaz-Ricci, J.-C. ; Métraux, Jean-Pierre ; Serrano, Mario

In: Plant Science, 2015, vol. 241, p. 120–127

AsES (Acremonium strictum Elicitor and Subtilisin) is a novel extracellular elicitor protein produced by the avirulent isolate SS71 of the opportunist strawberry fungal pathogen A. strictum. Here we describe the activity of AsES in the plant-pathogen system Arabidopsis thaliana–Botrytis cinerea. We show that AsES renders A. thaliana plants resistant to the necrotrophic pathogen B. cinerea, both...
