Description

General description

Gibberellic acid is an endogenous plant growth regulator

Gibberellic acid is a tetracyclic diterpenoid compound, which is synthesized by terpenoid pathway in chloroplasts, cytoplasm, plastid, and endoplasmic reticulum.

Application

Gibberellic acid has been used as a supplement in Murashige and Skoog media (MS) for treating young leaves of hybrid poplar to follow MYB transcription factor PtrMYB012 expression and in vitro peas seed germination. It has also been used in gibberellic acid (GA)-sensitivity assay in wheat seeds and to promote seed germination in Arabidopsis seeds.
The specific actions of Gibberellin A3 (G1025, G7645) and A4 (G7276) or combinations of Gibberellins should be determined in specific plant applications.

Biochem/physiol Actions

Phytohormone that controls important aspects of plant growth: germination, elongation, and flowering. The effects are mediated by inducing degradation of the DELLA repressor protein, and probably other minor signalling pathways.

Gibberellic acids (GA) are important plant growth hormones that promote plant cell growth and elongation. Gibberellins 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 and flowering.
