Indole-2-Acetic Acid

Description:
Indole-2-acetic acid (IAA) is a naturally occurring plant hormone belonging to the auxin class, playing a crucial role in regulating plant growth and development. It is characterized by its indole structure, which consists of a fused benzene and pyrrole ring, with an acetic acid functional group attached at the 2-position. This compound is typically a white to pale yellow crystalline solid, soluble in polar solvents such as water and ethanol. IAA is involved in various physiological processes, including cell elongation, apical dominance, root formation, and responses to light and gravity. Its action is mediated through specific receptors and signaling pathways, influencing gene expression and cellular activities. Additionally, IAA can be synthesized through various pathways in plants, primarily from the amino acid tryptophan. Due to its significant role in plant biology, indole-2-acetic acid is widely studied for its applications in agriculture and horticulture, particularly in promoting root growth and enhancing crop yields.
