The developmental switch from a vegetative phase to reproduction (flowering) is essential for reproduction success in flowering plants, and the timing of the floral transition is regulated by various environmental factors, among which seasonal day-length changes play a critical role to induce flowering at a season favorable for seed production. The photoperiod pathways are well known to regulate flowering time in diverse plants. Here, we summarize recent progresses on molecular mechanisms underlying the photoperiod control of flowering in the long-day plant Arabidopsis as well as the short-day plant soybean; furthermore, the conservation and diversification of photoperiodic regulation of flowering in these two species are discussed.
从营养生长阶段向生殖阶段（开花）的发育转变对于开花植物的繁殖成功至关重要，而花发育的时间节点由各种环境因素调控，其中季节性日长变化在诱导有利于种子生产的季节开花方面起着关键作用。光周期途径已被广泛证实可调控多种植物的开花时间。在此，我们总结了长日照植物拟南芥和短日照植物大豆中光周期调控开花的分子机制的最新进展；此外，还讨论了这两个物种中开花光周期调控的保守性和多样性。
