Auxin and its role in plant development: structure, signalling, regulation and response mechanisms.
Plant biology, 2021Auxins are plant hormones that play a central role in controlling plant growth and development across different environmental conditions. Even at low concentrations, auxins can regulate gene expression through specific transcription factors and proteins ...

Auxins and Auxin Precursors in Plants
Nature, 1953THE principal auxin in higher plants is generally believed to be indoleacetic acid, which is supposed to arise from tryptophane (a) via indoleiminoacetic acid, indolepyruvic acid and indole acetaldehyde, or (b) via tryptamine and indole acetaldehyde1. The general occurrence of tryptophane in the plant kingdom is well established.

Trends in Plant Science, 2001
Our understanding of phyllotaxis is still largely based on surgical and pharmacological experiments carried out before 1970. Recent experiments implicate the plant hormone auxin in the regulation of phyllotaxis. A recent paper shows how the polar auxin transport mutant, pin1-1, which fails to make flowers, affects the expression of well known meristem ...

Auxin is a multifactorial phytohormone that is required for cell division. Fine gradients determine points of developmental change in time and space. It is associated intimately with the axiality of plant growth, and increasing doses lead to cell expansion or inhibition of cell expansion in different tissues.

The best-known phytohormones from the auxin family contain the indole ring system substituted, at its 3-position, with a short aliphatic side chain ending in a free carboxyl group. Their most common endogenous representative is indole-3-acetic acid (IAA). A variety of its ring- and side-chain substituted derivatives have been prepared by chemical means.

Impermeant auxin analogues have auxin activity
Planta, 1990Protein conjugates of 5-aminonaphthalene-1-acetic acid and of 5-azido-naphthalene-1-acetic acid have been prepared and evaluated for auxin activity in two types of assay. In standard elongation tests with pea (Pisum sativum L.) epicotyl sections the conjugates are inactive.

AUXIN TRANSPORT, AUXIN METABOLISM AND AGEING
Acta Botanica Neerlandica, 1969SUMMARY Transport and metabolism of auxin have been studied in explants of Coleus. An ageing period preceding a transport experiment causes a decrease in the amounts of radioactivity transported. A pre-treatment with auxin during the ageing period maintains the transport on the original level.

Auxin Receptors and Auxin Binding Proteins
Critical Reviews in Plant Sciences, 1995Abstract In the last few years, a large number of auxin-binding proteins (ABPs) have been reported. Implicitly or explicitly, interest in such proteins resides in their possible role as auxin receptors. Many of these proteins are characterized as ABPs solely by their susceptibility to covalent photolabeling by tritiated azido-indole-3-acetic acid.

Current Opinion in Plant Biology, 2005
Polar transport of auxin is essential for normal plant growth and development. On a cellular level, directional auxin transport is primarily controlled by an efflux carrier complex that is characterized by the PIN-FORMED (PIN) family of proteins. Detailed developmental studies of PIN distribution and subcellular localization have been combined with the
