Abstract:

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.

Key words: Maize, Photoperiod sensitivity, Photoperiodic pathway, Gene cloning
