Local, Efflux-Dependent Auxin Gradients as a Common Module for Plant Organ Formation
Eva Benková,Marta Michniewicz,Michael Sauer,Thomas Teichmann,Daniela Seifertová,Gerd Jürgens,Jiří Friml +6 more
TL;DR: It is shown that organ formation in Arabidopsis involves dynamic gradients of the signaling molecule auxin with maxima at the primordia tips, which suggest that PIN-dependent, local auxin gradients represent a common module for formation of all plant organs, regardless of their mature morphology or developmental origin.
Journal ArticleDOI
Lateral relocation of auxin efflux regulator PIN3 mediates tropism in Arabidopsis
TL;DR: It is shown that auxin accumulates asymmetrically during differential growth in an efflux-dependent manner and that actin-dependent relocalization of PIN3 in response to gravity provides a mechanism for redirecting auxin flux to trigger asymmetric growth.
Journal ArticleDOI
PIN Proteins Perform a Rate-Limiting Function in Cellular Auxin Efflux
Jan Petrášek,Jozef Mravec,Rodolphe Bouchard,Joshua J. Blakeslee,Melinda Abas,Daniela Seifertová,Justyna Wiśniewska,Zerihun Tadele,Martin Kubeš,Milada Čovanová,Pankaj Dhonukshe,Petr Skůpa,Eva Benková,Lucie Perry,Pavel Křeček,Ok Ran Lee,Gerald R. Fink,Markus Geisler,Angus S. Murphy,Christian Luschnig,Eva Zazímalová,Jiri Friml +21 more
TL;DR: Conditional gain-of-function alleles and quantitative measurements of auxin accumulation revealed that the action of PINs in auxin efflux is distinct from PGP, rate-limiting, specific to auxins, and sensitive to auxin transport inhibitors, which suggests a direct involvement ofPINs in catalyzing cellular auxIn efflux.
Journal ArticleDOI
Nitrate-Regulated Auxin Transport by NRT1.1 Defines a Mechanism for Nutrient Sensing in Plants
Gabriel Krouk,Benoît Lacombe,Agnieszka Bielach,Francine Perrine-Walker,Katerina Malinska,Emmanuelle Mounier,Klára Hoyerová,Pascal Tillard,Sarah Leon,Karin Ljung,Eva Zazímalová,Eva Benková,Philippe Nacry,Alain Gojon +13 more
TL;DR: It is proposed that NRT1.1 represses lateral root growth at low nitrate availability by promoting basipetal auxin transport out of these roots, which defines a mechanism connecting nutrient and hormone signaling during organ development.
Journal ArticleDOI
Polar PIN localization directs auxin flow in plants.
Justyna Wiśniewska,Jian Xu,Jian Xu,Daniela Seifertová,Daniela Seifertová,Philip B. Brewer,Philip B. Brewer,Kamil Růžička,Kamil Růžička,Ikram Blilou,Ikram Blilou,David Rouquié,David Rouquié,Eva Benková,Eva Benková,Ben Scheres,Ben Scheres,Jiri Friml,Jiri Friml +18 more
TL;DR: Interfering with sequence-embedded polarity signals directly demonstrates that PIN polarity is a primary factor in determining the direction of auxin flow in meristematic tissues.
