玉米光周期途径相关基因的研究进展

Research progress of genes related to photoperiodic pathway in maize

引进热带、亚热带玉米种质资源是拓宽我国玉米种质资源的有效途径。由于玉米种质对日长和光周期的响应存在差异,阻碍了温带、热带、亚热带不同纬度地区之间玉米种质资源的交流和利用。近年来,玉米光周期途径相关基因不断得到研究并被克隆出来,但对其光周期调控网络、分子机理还有待进一步研究。文章综述了玉米光周期敏感性遗传特征、光周期相关基因定位,并以拟南芥和水稻为参考,对玉米光周期途径相关基因克隆及功能进行了阐述,以期为玉米光周期途径调控网络及分子机理研究提供参考。

Introducing tropical and subtropical maize varieties is a good strategy to expand the maize germplasm resources in China.However the exchange and use of maize germplasm resources at various latitudes of temperate,tropical,and subtropical regions are hampered by the variation in how maize germplasm reacts to day length and photoperiod.In recent years,maize photoperiodic pathway related genes have been continuously studied and cloned,but more research is needed to understand the photoperiodic regulatory network and molecular mechanisms.This paper summarized the genetic characteristics of maize photoperiod sensitivity and the mapping of photoperiod related genes,explained the cloning and function of maize photoperiodic pathway related genes with reference to Arabidopsis and rice,in order to provide reference for the research on regulation network and molecular mechanism of maize photoperiodic pathway.
