AGAMOUS like 6亚家族基因研究进展

摘要

开花是植物由营养生长向生殖生长转变的重要过程,许多开花相关基因参与这一过程,AGAMOUS like 6(AGL6)亚家族是其中的重要一类,AGL6亚家族基因编码MIKC-type MADS box转录因子,含有MADS-box保守结构域,通过多条途径参与花时的调节及花器官发育.该文对AGL6及其同源基因的结构、功能、进化以及与其它相关基因之间的调控关系进行综述,并对该基因研究中存在的一些问题及今后的研究方向进行了讨论.%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.
