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, 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. 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.
