Abstract: Dwarf mutant has very important effect on elucidating regulation mechanism of stem development and plant breeding. The research shows that， gibberellin (GA) has a close relationship with dwarf mutant. Approximately all of the genes involved in the biosynthesis of the biologically active GA have now been isolated， using different kinds of strategies. In recent years， a series of new strategies has promoted the research development of GA regulation. Here we summarize the cloning of the genes involved in the biosynthesis of the biologically active GA， the GA signaling transduction， and how to do with the GA regulation.
