Description

General description

Gibberellic acid is a tetracyclic diterpenoid compound, which is synthesized by terpenoid pathway in chloroplasts, cytoplasm, plastid, and endoplasmic reticulum.[1]

Gibberellic acid is an endogenous plant growth regulator

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[2] and in vitro peas seed germination.[3] It has also been used in gibberellic acid (GA)-sensitivity assay in wheat seeds[4] and to promote seed germination in Arabidopsis seeds.[5]
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

Gibberellic acids (GA) are important plant growth hormones that promote plant cell growth and elongation.[6] Gibberellins promote rapid stem and root growth, induce mitotic division and initiate (break dormancy) and increase seed germination rates.[1] The gibberellins are also involved in processes such as gravitropism and flowering.[7]

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.
