General description

Gibberellic acid is an endogenous plant growth regulator

Application

Gibberellic acid has been used to study mechanical properties with cellular resolution in the light-grown hypocotyl of Arabidopsis thaliana.

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.
