The main auxin in plants is indole-3-acetic acid (IAA). Auxin concentration varies depending on the part of the plant and the various concentrations are strictly regulated by the plant. The regulation of the auxin concentrations creates a pattern-like system which helps determine plant growth and development. IAA is predominantly produced in the apical bud of and young leaves of plants and is known to be an inducer of cell division and elongation. IAA, as well as most other auxins, are also known to act in concert with, or in opposition to, other plant hormones. 

Features:

IAA is often used in horticulture to promote adventitious root growth and are used commercially to create root stem cuttings and to promote uniform fruit and flowering growth.
