Odyssey of Auxin [PDF]

Cold Spring Harbor Perspectives in Biology, 2010
The history of plant biology is inexorably intertwined with the conception and discovery of auxin, followed by the many decades of research to comprehend its action during growth and development. Growth responses to auxin are complex and require the coordination of auxin production, transport, and perception. In this overview of past auxin research, we

Mutual inhibition between EPFL2 and auxin extends the intervals of periodic leaf morphogenesis

Nature Communications
Rules behind the spatial arrangement of repetitive modules are key principles of multicellular morphogenesis. In plant shoots, PIN-FORMED 1 (PIN1)-mediated polar auxin transport instructs periodic formation of auxin maxima, which develop into lateral ...

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.

The Biphasic Root Growth Response to Abscisic Acid in Arabidopsis Involves Interaction with Ethylene and Auxin Signalling Pathways

Frontiers in Plant Science, 2017
Exogenous abscisic acid (ABA) is known to either stimulate or inhibit root growth, depending on its concentration. In this study, the roles of ethylene and auxin in this biphasic effect of ABA on root elongation were investigated using chemical ...

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 ...

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 ...

Breaking ground: ABLs and TMKs as co-receptors to perceive extracellular auxin

Advanced Agrochem
Auxin is an important phytohormone that regulates a string of vital rapid responses, and its signaling perception mechanism has been one of the hot spots of research.

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.

Both Induction and Morphogenesis of Cyst Nematode Feeding Cells Are Mediated by Auxin

Molecular Plant-Microbe Interactions, 2000
Various lines of evidence show that local changes in the auxin concentration are involved in the initiation and directional expansion of syncytia induced by cyst nematodes.

Cellular Auxin Transport in Algae

Plants, 2014
The phytohormone auxin is one of the main directors of plant growth and development. In higher plants, auxin is generated in apical plant parts and transported from cell-to-cell in a polar fashion.
