Indole-3-acetic acid (IAA) is the main auxin in plants, controlling many important physiological processes including cell enlargement and division, tissue differentiation, and responses to light and gravity (45).
How do you use indole-3-acetic acid?
The regulation of the auxin concentrations creates a pattern-like system which helps determine plant growth and development. IAA is often used in horticulture to promote adventitious root growth and are used commercially to create root stem cuttings and to promote uniform fruit and flowering growth.
Is indole-3-acetic acid?
Indole-3-acetic acid is a monocarboxylic acid that is acetic acid in which one of the methyl hydrogens has been replaced by a 1H-indol-3-yl group. It has a role as a plant hormone, a human metabolite, a plant metabolite, a mouse metabolite and an auxin.
What is the other name of indole-3-acetic acid?
Indole-3-acetic acid (IAA, 3-IAA) is the most common naturally occurring plant hormone of the auxin class….Indole-3-acetic acid.

What is indole 3 carbinol used for?
Overview. Indole-3-carbinol is a substance found in vegetables such as broccoli, Brussels sprouts, cabbage, collards, cauliflower, kale, mustard greens, turnips, and rutabagas. It can also be produced in the laboratory. Indole-3-carbinol is used for prevention of breast cancer, colon cancer, and other types of cancer.
What is NAA plant hormone?
NAA is a synthetic plant hormone in the auxin family and is an ingredient in many commercial plant rooting horticultural products; it is a rooting agent and used for the vegetative propagation of plants from stem and leaf cuttings. It is also used for plant tissue culture.
Is indole-3-acetic acid water soluble?
Indole-3-Acetic Acid (IAA) is poorly soluble in H2O or aqueous buffers, unless the pH of the solvent is alkaline. 1N NaOH is the preferable solvent to dissolve IAA.
Which is the precursor of indole-3-acetic acid?
Indole-3-acetic acid (IAA), the main auxin produced by plants, is known to be synthesized de novo using tryptophan (Trp) as a precursor or using a Trp-independent pathway (reviewed in Zhao, 2010).
Who discovered Auxins?
In 1928, Dutch botanist Fritz W. Went finally isolated auxin diffused out from the tip of oat coleoptiles in the gelatin block. Following Went’s success, auxin, indole-3-acetic acid (IAA) was then isolated first from human urine, then from fungi, and finally from higher plants.
Is indole-3-carbinol and estrogen blocker?
Studies increasingly indicate that dietary indole-3-carbinol (I3C) prevents the development of estrogen-enhanced cancers including breast, endometrial and cervical cancers. Epidemiological, laboratory, animal and translational studies support the efficacy of I3C.
What is the difference between dim and indole-3-carbinol?
DIM is formed naturally when I3C is broken down in the gut. Unlike I3C, there are no published human studies on DIM. In fact, there are few published studies at all….ANTI-CANCER EFFECTS OF I3C.

What is the difference between IAA and NAA?
The reason of these differences connects with the steric properties of both auxins; namely, the naphthalene ring of NAA molecule occupies larger space than the indole system of IAA. Therefore molecules of the latter compound penetrate easier into the region of phospholipids׳ polar head-groups.
