Auxin-dependent post-translational regulation of MONOPTEROS in the Arabidopsis root

Cell Reports
Summary: Auxin plays a pivotal role in plant development by activating AUXIN RESPONSE FACTORs (ARFs). Under low auxin levels, ARF activity is inhibited by interacting with Aux/IAAs.

Auxin influx carriers control vascular patterning and xylem differentiation in Arabidopsis thaliana.

PLoS Genetics, 2015
Auxin is an essential hormone for plant growth and development. Auxin influx carriers AUX1/LAX transport auxin into the cell, while auxin efflux carriers PIN pump it out of the cell.

Parsimonious Model of Vascular Patterning Links Transverse Hormone Fluxes to Lateral Root Initiation: Auxin Leads the Way, while Cytokinin Levels Out.

PLoS Computational Biology, 2015
An auxin maximum is positioned along the xylem axis of the Arabidopsis root tip. The pattern depends on mutual feedback between auxin and cytokinins mediated by the PIN class of auxin efflux transporters and AHP6, an inhibitor of cytokinin signalling ...

Actin Isovariant ACT2‐Mediated Cellular Auxin Homeostasis Regulates Lateral Root Organogenesis in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Lateral root (LR) organogenesis is regulated by cellular flux of auxin within pericycle cells, which depends on the membrane distribution and polar localization of auxin carrier proteins. The correct distribution of auxin carrier proteins relies on the intracellular trafficking of these proteins aided by filamentous actin as a track.

A family of auxin conjugate hydrolases from Solanum lycopersicum and analysis of their roles in flower pedicel abscission

BMC Plant Biology, 2019
Background Auxin conjugates are hydrolyzed to release free auxin to ensure defined cellular auxin levels or gradients within tissues for proper development or response to environmental signals.

A magnetically enabled simulation of microgravity represses the auxin response during early seed germination on a microfluidic platform

Microsystems & Nanoengineering, 2022
For plants on Earth, the phytohormone auxin is essential for gravitropism-regulated seedling establishment and plant growth. However, little is known about auxin responses under microgravity conditions due to the lack of a tool that can provide an ...

RALFL34 regulates formative cell divisions in Arabidopsis pericycle during lateral root initiation [PDF]

, 2016
We describe the role of RALFL34 during early events in lateral root development, and demonstrate its specific importance in orchestrating formative cell divisions in the pericycle.In plants, many signalling molecules, such as phytohormones, miRNAs ...

Agent‐Based Computational Modeling of the Stochastic Dynamic Behavior of Actin Filaments Recapitulates the Homeostatic Cortical Array in Plant Epidermal Cells

Cytoskeleton, EarlyView.
ABSTRACT The homeostatic cortical actin array in plant cells plays important roles in fundamental processes, including intracellular transport, secretion, cell expansion, and cytoplasmic streaming. In response to diverse chemical and mechanical signals, the cortical array can remodel within minutes to assume new configurations or altered filament ...

The AUXIN BINDING PROTEIN 1 is required for differential auxin responses mediating root growth.

PLoS ONE, 2009
BackgroundIn plants, the phytohormone auxin is a crucial regulator sustaining growth and development. At the cellular level, auxin is interpreted differentially in a tissue- and dose-dependent manner.
