Indole-3-Acetic Acid

Indole-3-Acetic Acid (or IAA) is a member of the Auxin family of Plant Growth Regulators, or PGRs.

IAA is synthesized organically, and has a complex synthesis process. IAA is converted in plants from the Amino Acid, Tryptophan, but can be internally manufactured without it. Tryptophan creates Auxins, like IAA, when Sieve Vascular Tissue Tube Elements of the plant (responsible for carbohydrate transport) undergo Apoptosis, or cell death. Tryptophan is also responsible for the chemical synthesis of Niacin, and is organically synthesized with Indole, or synthetically manufactured by the hydrolysis of Casein.

IAA is responsible for both cell elongation and cell division. Studies of IAA were responsible for the discovery of 2,4-Dichlorophenoxyacetic Acid (a synthetic Auxin). Like most organic Auxins, IAA is less potent than its synthetic counterparts: 1-Naphthaleneacetic Acid, Indole-3-Butyric Acid and 2,4-Dichlorophenoxyacetic Acid.

IAA is commonly used with a Cytokinin, such as 6-Benzylaminopurine.
