Flowering is an important process for plants to transfer from vegetative to reproductive development.Many genes are involved in the process,and AGAMOUSlike6 (AGL6) subfamily is one of the essential genes.The AGL6 gene encodes a MIKC type MADS box transcription factor that contains MADSbox conserved domains.It regulate flowering time and floral organ development through many ways.This paper reviews the recent research progresses in AGL6 and AGL6 homologous gene,including their structures,functions,evolution and the interaction with other genes.Finally,we discuss the problems in the present study and the research hot points in future.
