Detailed explanation-1: -Plants as well as microorganisms, including bacteria and fungi, produce indole-3-acetic acid (IAA). IAA is the most common plant hormone of the auxin class and it regulates various aspects of plant growth and development.

Detailed explanation-2: -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.

Detailed explanation-3: -The most prevalent naturally occurring auxin in plants is Indole-3-Acetic Acid (IAA). Indole-3-Acetic Acid (IAA) is mostly synthesized in the apical buds of young shoots. It has been shown to stimulate cell elongation and division.

Detailed explanation-4: -Indole 3-butyric acid (IBA) is an auxin precursor that is converted to IAA in a peroxisomal -oxidation process. In Arabidopsis, altered IBA-to-IAA conversion leads to multiple plant defects, indicating that IBA contributes to auxin homeostasis in critical ways.

Detailed explanation-5: -Indole-3-acetic acid (IAA) represents the most common auxin in plants and can be synthesized from its tryptophan precursor, which is synthesized in the chloroplast.
