INDOLEACETIC ACID Meaning and
Definition
-
Indoleacetic acid (IAA) is a naturally occurring plant hormone, belonging to the auxin family, that plays a crucial role in various physiological processes in plants. IAA is an organic compound with a chemical formula of C10H9NO2. It is a derivative of the amino acid tryptophan and is primarily synthesized in the apical meristems (growing tips) of plants.
Indoleacetic acid is involved in numerous plant growth and developmental processes, including cell elongation, division, and differentiation. It influences the bending of stems towards sunlight (phototropism) and the growth of roots away from gravitational forces (gravitropism). IAA also regulates the formation of lateral roots and promotes the growth of fruits.
One of the key functions of indoleacetic acid is its involvement in tropism responses, which are plant movements in response to stimuli. It aids in the growth of plant tissues towards or away from light, gravity, moisture, or other stimuli. IAA acts by regulating gene expression, promoting cell expansion, and influencing other plant hormones.
The synthesis and transport of indoleacetic acid within plants are tightly regulated to maintain the appropriate hormone levels for normal growth and development. Imbalances in IAA levels can result in abnormal growth patterns, such as stunted growth or excessive elongation.
Furthermore, indoleacetic acid has also been utilized in various agricultural practices to regulate plant growth, induce rooting in cuttings, prevent premature fruit drop, and promote fruit development. Its applications extend to horticulture, tissue culture, and even weed control.

Etymology of INDOLEACETIC ACID
The word "Indoleacetic Acid" is derived from its chemical structure and composition.
"Indole" refers to a chemical compound called indole, which is a derivative of the aromatic compound benzene. This name comes from the French word "indigo", as indole was originally isolated from indigo dye.
"Acetic Acid" refers to a simple carboxylic acid called acetic acid, which is commonly found in vinegar. The term "acetic" is derived from the Latin word "acetum", meaning vinegar.
So, "Indoleacetic Acid" combines the terms "indole" and "acetic acid" to describe a compound that consists of an indole group attached to an acetic acid molecule.
