General Description

Indole-3-acetic acid is a plant growth regulator. Indole-3-acetic acid induces cell division and cell elongation that promotes plant growth.

Biological Activity

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.
