An indole-based auxin for plant cell culture. Synonym: Heteroauxin
C10H9NO2
M.W.: 175.18
IAA was the first plant hormone discovered and was initially called heteroauxin (Went and Thimann, 1937). IAA belongs to the auxin class of plant growth regulators that promote root organogenesis and growth, induce callus formation, form adventitious roots, aids in regulation of gravitropism and phototropism, and can induce embryogenesis. IAA can be synthesized in plants from the amino acid tryptophan (Hull et al. 2000).
IAA will retain 60% of its activity in MS media following a 60 minute autoclave cycle (Nissen and Sutter, 1990). IAA is also sensitive to light and metal salts, and will retain 50% of its original activity following 14 days in liquid MS media (Dunlap et al. 1986).
