The IAA can also be expended as Indole-3-acetic acid is one of the most common plant hormone. The IAA belong to the Naturally Occurring Harmon of the auxin class can also be found in soil inhabited microorganisms.
The IAA is known for its main function of regulating the plant gene. Back in 1997, it has been explained that how the auxin response factor bind to the auxin response gene element in order to promote gene regulation.
It has also been concluded with an experiment, that the IAA can be synthesized artificially by adding Indol with glycolic acid.
Indole-3-acetic acid (IAA, 3-IAA) is the most common, naturally occurring, plant hormone of the auxin class. It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists. IAA is a derivative of indole, containing a carboxymethyl substituent. It is a colorless solid that is soluble in polar organic solvents.
Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. Example: Indole Acetic Acid (IA). Auxin is a plant hormone produced in the stem tip that promotes cell elongation
