Auxins (plural of auxin / ˈ ɔː k s ɪ n /) 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, 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.

2018年5月13日 · 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. The other major groups are the gibberellins, cytokinins, ethylene, and abscisic acid.

Auxins are a group of naturally occurring and artificially synthesised plant hormones. They play an important role in the regulation of plant growth. Auxins were initially isolated from human urine. Auxin means to “enlarge” or “increase”. They induce cell division, differentiation and elongation.

2024年5月17日 · Auxin is a plant hormone. Auxin hormone function is to control growth and developmental processes in plants, including cell expansion, root initiation, and bud and flower growth. Auxin, discovered by Charles Darwin and his …

2023年2月17日 · An auxin is a group of growth hormones found in all plant tissues in varying concentrations. The name of this class of hormone comes from the Greek word ‘ auxein ‘, which means ‘to grow’ or ‘increase’. It was the first significant plant hormone to be discovered.

Greg Foot explains how plants respond to light and gravity, and the role of auxins in controlling and coordinating plant growth. A chemical process used by plants to make glucose and oxygen from...
