Abstract
The gibberellin (GA) biosynthetic pathway in plants is regulated by a feedback mechanism that operates in part through repression of genes encoding key biosynthetic enzymes, including a GA 20-oxidase. We propose to identify mutants that affect this feedback mechanism through the construction of transgenic lines carrying 20-oxidase promoter- reporter gene fusions, using alcohol dehydrogenase (ADH) and green fluorescent protein (GFP) as selectable and visible reporters respectively. As this GA feedback mechanism has components in common with the GA response pathway, the genes identified in this project will have valuable applications in the manipulation of plant development.
