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

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.

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.

Effect of auxins on the auxin transport system in coleoptiles
Planta, 1969Within 20 min of its application, auxin enhances the transport processes that move auxin molecules through coleoptile tissue. The effect was observed after treatment with indoleacetic acid and α-naphthaleneacetic acid, but not with growth-inactive auxin analogues.

Journal of Plant Growth Regulation, 2001
Differential growth of plants in response to the changes in the light and gravity vectors requires a complex signal transduction cascade. Although many of the details of the mechanisms by which these differential growth responses are induced are as yet unknown, auxin has been implicated in both gravitropism and phototropism.

Auxin signaling is key to many plant growth and developmental processes from embryogenesis to senescence. Most, if not all, of these processes are initiated and/or mediated through auxin-regulated gene expression. Two types of transcription factor families are required for controlling expression of auxin response genes. One of these, the auxin response

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.

Annual Review of Plant Physiology and Plant Molecular Biology, 1997
▪ Abstract Indole-3-acetic acid (IAA) is the most abundant naturally occurring auxin. Plants produce active IAA both by de novo synthesis and by releasing IAA from conjugates. This review emphasizes recent genetic experiments and complementary biochemical analyses that are beginning to unravel the complexities of IAA biosynthesis in plants.

Current Opinion in Cell Biology, 1995
Recent work on the auxin signal has yielded clear answers to some questions and produced puzzling new data to explain. It is now established that the auxin-binding protein functions extracellularly, but it is unclear how it reaches that location. Important clues on the mechanism(s) by which auxin achieves its genetic and cell biological effects are ...

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.
