Question
Write short notes on Indole Acetic Acid.
Answer
Indole-3-acetic acid (IAA) is the most common and well-studied auxin, a class of plant hormones that regulate growth and development. IAA is synthesized from the amino acid tryptophan through the indole-3-acetic acid biosynthesis pathway in plants. It plays crucial roles in processes such as cell elongation, apical dominance, root initiation, and tropisms (directional growth in response to environmental stimuli).
