Abstract:In recent years, with the development of research methods and technology, great progresses have been made in the study of gibberellins biosynthesis and its mechanism of regulation. The formation of precursor of gibberellin biosynthesis and evolution of various gibberellins were included. The research progress in the key enzymes such as copalyl pyrophosphate synthase, ent-kaurene synthase, GA20-oxidase, GA3-hydroxylase were summarized. The research progress in the regulation mechanism of GA 20-oxidase, GA 3-hydroxylase in the process of gibberellins biosynthesis was summarized especially.
Keywords:plant physiology  higher plants  gibberellin  biosynthesis  key enzymes
