Photoaffinity-labeled Auxins [PDF]
Plant Physiology, 1975 Two light-sensitive analogs of 2,4-dichlorophenoxyacetic acid, namely 4-azido-2-chlorophenoxyacetic acid and 3-azido-5-chlorophenoxyacetic acid, have been synthesized for use as auxin photoaffinity labels. The preparation and biological activity of the compounds are described. Both contain the photolabile azido group; the 2,4-substituted compound shows

Comprehensive RNA-Seq Analysis on the Regulation of Tomato Ripening by Exogenous Auxin. [PDF]
PLoS ONE, 2016 Auxin has been shown to modulate the fruit ripening process. However, the molecular mechanisms underlying auxin regulation of fruit ripening are still not clear. Illumina RNA sequencing was performed on mature green cherry tomato fruit 1 and 7 days after

The Developmental Mechanism of the Root System of Cultivated Terrestrial Watercress
Plants, 2023 A well-developed root system is crucial for the rapid growth, asexual reproduction, and adaptation to the drought environments of the watercress. After analyzing the transcriptome of the watercress root system, we found that a high concentration of auxin

Cell kinetics of auxin transport and activity in Arabidopsis root growth and skewing
Nature Communications, 2021 Auxin gradients regulate plant root growth and development. Here the authors manipulate auxin synthesis in specific root cell types and use single-cell nucleus tracking and morphokinetics to map directional auxin flow in the root and quantify the ...

The roles of epigenetic modifications in the regulation of auxin biosynthesis
Frontiers in Plant Science, 2022 Auxin is one of the most important plant growth regulators of plant morphogenesis and response to environmental stimuli. Although the biosynthesis pathway of auxin has been elucidated, the mechanisms regulating auxin biosynthesis remain poorly understood.

Involvement of nitrate reductase in auxin-induced NO synthesis [PDF]
Plant Signaling & Behavior, 2008 It is well known for a long time, that nitric oxide (NO) functions in variable physiological and developmental processes in plants, however the source of this signaling molecule in the diverse plant responses is very obscure.1 Although existance of nitric oxide sythase (NOS) in plants is still questionable, LNMMA (N(G)-monomethyl-L-arginine)-sensitive ...

The pea branching RMS2 gene encodes the PsAFB4/5 auxin receptor and is involved in an auxin-strigolactone regulation loop. [PDF]
PLoS Genetics, 2017 Strigolactones (SLs) are well known for their role in repressing shoot branching. In pea, increased transcript levels of SL biosynthesis genes are observed in stems of highly branched SL deficient (ramosus1 (rms1) and rms5) and SL response (rms3 and rms4)

Indole-3-acetaldehyde dehydrogenase-dependent auxin synthesis contributes to virulence of Pseudomonas syringae strain DC3000. [PDF]
PLoS Pathogens, 2018 The bacterial pathogen Pseudomonas syringae modulates plant hormone signaling to promote infection and disease development. P. syringae uses several strategies to manipulate auxin physiology in Arabidopsis thaliana to promote pathogenesis, including its ...

Subcellular trafficking and post-translational modification regulate PIN polarity in plants
Frontiers in Plant Science, 2022 Auxin regulates plant growth and tropism responses. As a phytohormone, auxin is transported between its synthesis sites and action sites. Most natural auxin moves between cells via a polar transport system that is mediated by PIN-FORMED (PIN) auxin ...
