Abstract

Gibberellins (GAs) are active in many developmental processes such as flowering and stem elongation. GAs are inactivated by the action of GA 2-oxidase, which is encoded by a small gene family with different expression patterns. The aim of this proposal is to test the hypothesis that GA2ox activity is necessary for GA homeostasis and for maintaining the tissue-specificity of GA action by protecting GA-sensitive tissues against stimulation by bioactive GAs. This will be achieved by determining the expression of GA2ox genes in parallel with detailed GA analysis, by studying the effects of loss-of-function mutations in each GA2ox gene and by manipulation of GA inactivation in transgenic plants.
