Description

General description

Indole-3-acetic acid (IAA) is a plant hormone and a natural form of phytoalexins that belongs to the class of auxins. It is synthesized by plants and plant-associated microorganisms including ectomycorrhizal, endophytic fungi, [1] and plant growth-promoting rhizobacteria. IAA is the product of L- tryptophan metabolism.

Application

Indole-3-acetic acid (IAA) sodium salt has been used:

• to alter the root developmental processes in Arabidopsis thaliana seedlings
• as a standard for the determination of IAA by high-performance liquid chromatography using Chlorella sorokiniana and Azospirillum brasilense sample culture media
• as one of the plant hormone to treat interspecific hybrids (Elaeis oleifera Cortés x Elaeis guineensis Jacq.) and study its effect on bunch formation in parthenocarpic fruits and oil production in oil palm
• as a supplement in culture media to induce mitotic slippage in human cell lines
• as a supplement in a shoot induction medium (SIM) for shooting and shoot elongation from explant

Biochem/physiol Actions

Indole-3-acetic acid (IAA) is a plant growth regulator. Indole-3-acetic acid induces root initiation, cell division, and cell elongation which promotes plant growth. [1] It mediates organ development, fertility, cell orientation, and elongation. Overproduction of IAA is found to trigger ethylene production and therefore inhibit plant growth. In addition, up-regulation of IAA by pathogenic bacteria causes excess cellular division leading to gall disease in the plant. [2]
