Auxin - Wikipedia
Auxins (plural of auxin / ˈɔːksɪn /) are a class of plant hormones (or plant-growth regulators) with some morphogen -like characteristics. Auxins play a cardinal role in coordination of many growth and behavioral processes in plant life cycles and are essential for plant body development.
Auxin (Plant): Definition, Function and Structure - Biology Dictionary
May 13, 2018 · An auxin is a plant hormone derived from the amino acid tryptophan. An auxin may be one of many molecules, but all auxin molecules are involved in some sort of cellular regulation. Auxin molecules are one of five major types of plant hormone.
Auxin | Definition, Functions, & Uses | Britannica
Auxin, any of a group of plant hormones that regulate growth, particularly by stimulating cell elongation in stems. Auxins also play a role in cell division and differentiation, in fruit development, in the formation of roots from cuttings, in the inhibition of lateral branching, and in leaf abscission.
