Gibberellin A4

The Uses of Gibberellin A4

Gibberellin A4 is a plant growth hormone that regulates growth and differentiation of plant cells for elongation, germination and enzyme induction.

The Uses of Gibberellin A4

Gibberellin A4 has been used as a supplement in Murashige and Skoog (MS) media for enhancing plant growth.

What are the applications of Application

Gibberellin A4 is a plant hormone responsible for promoting growth and elongation

Definition

ChEBI: Gibberellin A4 is a C19-gibberellin, initially identified in Gibberella fujikuroi and differing from gibberellin A1 by the substitution of the OH at C-7 (gibbane numbering) by H. It has a role as a plant metabolite. It is a lactone, a gibberellin monocarboxylic acid and a C19-gibberellin. It is a conjugate acid of a gibberellin A4(1-).

Biochem/physiol Actions

Gibberillic acids (GA) are important plant growth hormones that promote plant cell growth and elongation. Gebberillins promote rapid stem and root growth, induce mitotic division and initiate (break dormancy) and increase seed germination rates. The gibberellins are also involved in processes such as gravitropism, tensioning and floral display.
