Gibberellin dose-response regulation of GA4 gene transcript levels in Arabidopsis.

Plant physiology - 1 Aug 1998

Cowling R J, Kamiya Y, Seto H, Harberd N P

Abstract excerpt

The gibberellins (GAs) are a complex family of diterpenoid compounds, some of which are potent endogenous regulators of plant growth. As part of a feedback control of endogenous GA levels, active GAs negatively regulate the abundance of mRNA transcripts encoding GA biosynthesis enzymes. For example, Arabidopsis GA4 gene transcripts encode GA 3beta-hydroxylase, an enzyme that catalyzes the conversion of inactive...
