Indole compounds - auxin

WebAuxins are plant hormones that stimulate plant growth. An SPR study ( Quareshy, Uzunova, Prusinska, & Napier, 2024) employed the auxin receptor, TIR1, and related F-box proteins (F-box is a ~ 50 amino acid structural motif that mediates protein–protein interactions) to screen for the design of novel compounds with auxin activity. WebAuxins are indole-derived molecules that can control the division and elongation rate, as well as the identity or differentiation state of cells. Accumulation of and response to auxin have been shown to regulate many growth and developmental processes throughout embryonic and post-embryonic development.

It possesses an indole ring and a carboxylic acid function. A broader definition of auxin (s) would be a class of compounds that impact plant development in the way IAA does.

Auxins were the first of the major plant hormones to be discovered. They derive their name from the Greek word αυξειν (auxein – "to grow/increase"). Auxin is present in all parts of a plant, although in very different concentrations. The concentration in each position is crucial developmental information, so it is subject to tight regulation through both metabolism and transport. The result is the auxin creates "patterns" of auxin concentration maxima and minima i… WebIndole-3-acetonitrile (IAN) has been found mainly in plants of the Brassicaceae family, including Arabidopsis thaliana and Brassica chinensis, 86 which produce a large variety of indole compounds in sufficient quantity.
