Journal ArticleDOI
Flavonols Accumulate Asymmetrically and Affect Auxin Transport in Arabidopsis
TL;DR: The identification of several transparent testa, myb, and fls1 (for flavonol synthase1) alleles in a rol1-2 suppressor screen provides genetic evidence that flavonols interfere with shoot development in rol 1-2 seedlings.
Journal ArticleDOI
The Modified Flavonol Glycosylation Profile in the Arabidopsis rol1 Mutants Results in Alterations in Plant Growth and Cell Shape Formation
Christoph Ringli,Laurent Bigler,Benjamin M. Kuhn,Ruth-Maria Leiber,Anouck Diet,Diana Santelia,Beat Frey,Stephan Pollmann,Markus Klein +8 more
TL;DR: Results suggest that changes in the composition of flavonols can have a tremendous impact on plant development through both auxin-induced and Auxin-independent processes.
Journal ArticleDOI
The Protease-associated Domain and C-terminal Extension Are Required for Zymogen Processing, Sorting within the Secretory Pathway, and Activity of Tomato Subtilase 3 (SlSBT3)
Anna Cedzich,Franziska Huttenlocher,Benjamin M. Kuhn,Jens Pfannstiel,Leszek Gabler,Annick Stintzi,Andreas Schaller +6 more
TL;DR: A transgenic plant cell suspension culture was established as a versatile and efficient expression system for the subtilase SlSBT3 from tomato as mentioned in this paper, which was found to be a very stable enzyme, being fully active at 60 °C and showing highest activity at alkaline conditions with a maximum between pH 7.5 and 8.0.
Journal ArticleDOI
7-Rhamnosylated Flavonols Modulate Homeostasis of the Plant Hormone Auxin and Affect Plant Development
Benjamin M. Kuhn,Sanae Errafi,Rahel Bucher,Petre I. Dobrev,Markus Geisler,Laurent Bigler,Eva Zažímalová,Christoph Ringli +7 more
TL;DR: A detailed analysis revealed that interfering with flavonol rhamnosylation increases the concentration of auxin precursors and auxin metabolites, whereas auxin transport is not affected, suggesting that Flavonol glycosides play an important role in regulating plant development.
Journal ArticleDOI
Flavonol induced changes in PIN2 polarity and auxin transport in the Arabidopsis thaliana rol1 2 mutant require phosphatase activity
Benjamin M. Kuhn,Tomasz Nodzyński,Sanae Errafi,Rahel Bucher,Shibu Gupta,Bibek Aryal,Petre I. Dobrev,Laurent Bigler,Markus Geisler,Eva Zažímalová,Jiří Friml,Christoph Ringli +11 more
TL;DR: In vivo analysis of PINOID action, a kinase known to influence PIN protein localization in a PP2A-antagonistic manner, revealed a negative impact of flavonols on PINOIDs activity, suggesting that flavonol affect auxin transport by modifying the antagonistic kinase/phosphatase equilibrium.
