摘　　要：水稻开花调控是一个极其复杂的生命过程,由自身遗传因素和外界环境共同决定。光周期途径是调控水稻开花的关键途径,在这个途径中成花素基因Hd3a和RTF1处于核心地位,其上游调控途径主要包括Hd1依赖途径、Ehd1依赖途径及不依赖于Hd1和Ehd1的途径。这3条途径在汇集了光信号的各种信息后,将信号在Hd3a和RTF1处整合,并通过成花素形式将信息传递给下游开花基因,调控水稻开花。本文从成花素、光信号感受基因和昼夜节律基因、成花素上游调控基因、互作蛋白和下游调控基因等几方面阐述水稻开花光周期调控相关基因的研究现状,为水稻开花调控的深入研究提供参考。Rice flowering regulation is an extremely complex process, which is controlled by genetic factors and external environment. Photoperiodic regulatory pathway is pivotal to control flowering in rice, in which florigen genes Hd3a and RTF1 are at the core and they are regulated by upstream Hdl-dependent, Ehdl-dependent, as well as both Hdl- and Ehdl-independent pathways. The three pathways bring a variety of light signal information together to Hd3a and RTF1 for further integration, and then transmit the signals in the form of florigen to the downstream flowering related genes. In this review, we summarize the research progress of photoperiod regulated genes on flo- wering time in rice, including the photoreceptors and circadian rhythm genes, the florigens, its upstream, downstream and interacting genes. We hope to provide a reference for in-depth study of rice flowering regulation.
