Indole-3-acetic acid

Short Description:

Indole-3-acetic acid is an indole broad-spectrum plant growth regulator with auxin activity; Regulate the electron channels and proton channels of cell membrane. As a plant growth regulator, it can promote cell division, accelerate root formation, increase fruit setting and prevent fruit falling. It is obtained by the reaction of indole with glycolic acid.

Indole-3-acetic acid is used as a plant growth stimulant and analytical reagent. Indole-3-acetic acid, 3-indole acetaldehyde, 3-indole acetonitrile, ascorbic acid and other auxin substances exist naturally in nature. The precursor of indole-3-acetic acid biosynthesis in plants is tryptophan. The basic function of auxin is to regulate the growth of plants. It can not only promote growth, but also inhibit growth and organogenesis. Auxin not only exists in free state in plant cells, but also exists in bound auxin that can be firmly bound with biopolymers, and also has auxin that forms a binding with special substances, such as indole acetyl asparagine, indole acetic acid pentose, indole acetyl glucose, etc. This may be a storage mode of auxin in cells, and it is also an detoxification mode to remove the toxicity of excess auxin.
