Plants must accurately integrate external environmental signals with their own development to initiate flowering at the appropriate time for reproductive success. Photoperiod and temperature are key external signals that determine flowering time; both are cyclical and periodic, and they are closely related. In this review, we describe photoperiod-sensitive genes that simultaneously respond to temperature signals in rice (Oryza sativa). We introduce the mechanisms by which photoperiod and temperature synergistically regulate heading date and regional adaptation in rice. We also discuss the prospects for designing different combinations of heading date genes and other cold tolerance or thermo-tolerance genes to help rice better adapt to changes in light and temperature via molecular breeding to enhance yield in the future.
植物必须准确地将外部环境信号与其自身的发育相结合，以便在适当的时间进行繁殖成功的开花。光周期和温度是决定开花时间的关键外部信号；两者都是周期性和周期性的，并且密切相关。在这篇综述中，我们描述了同时对水稻（Oryza sativa）中的温度信号做出反应的光周期敏感基因。我们介绍了光周期和温度协同调节水稻抽穗期和区域适应性的机制。我们还讨论了设计不同组合的抽穗期基因和其他耐寒或耐热基因的前景，以帮助水稻通过分子育种更好地适应光和温度的变化，从而提高未来的产量。
