Indolacetic acid (indolyl-3-acetic acid), or IAA, is the main natural auxin produced by plants. It promotes plant growth and cellular differentiation.
Abstract In senescent leaves proteins are hydrolysed to amino-acids and peptides, which might be expected to release protein-bound auxin and also to provide considerable amounts of trypotophan which can be converted by many plant tissues to the auxin indolyl-3-acetic acid (IAA). We have therefore investigated the concentrations of auxin in senescent leaves.
Substituted indoles are structural elements of (and for some compounds the synthetic precursors for) the tryptophan-derived tryptamine alkaloids like the neurotransmitter serotonin, and melatonin. Other indolic compounds include the plant hormone auxin (indolyl-3-acetic acid.
