Abstract: The maintenance and termination of floral meristems plays key role in the floral organogenesis and metagenesis of plant. Successful floral meristems determinacy ensures the normal reproductive development and life cycle progression of plants. Many studies have shown that AGAMOUS(AG)gene,as a master regulator of both floral organ differentiation and floral determinacy,can coordinate various cell fate decisions in flower development. However,the molecular mechanism of AG involvement in the regulation of plant metagenesis and floral meristem maintenance and termination remains unclear. This paper summarized such research progress and current status of AG gene in regulating the floral meristem maintenance and termination in recent years,with a view to providing a reference for further study of the maintenance and termination of stem cells during floral organ differentiation as well as the molecular regulation between stem cell activity and other developmental processes.

Key words: AGAMOUS(AG)gene, floral meristem maintenance and termination, regulation mechanisms
