Seed dormancy is an adaptive trait in plants. Breaking seed dormancy determines the timing of germination and is, thereby essential for ensuring plant survival and agricultural production. Seed dormancy and the subsequent germination are controlled by both internal cues (mainly hormones) and environmental signals. In the past few years, the roles of plant hormones in regulating seed dormancy and germination have been uncovered. However, we are only beginning to understand how light signaling pathways modulate seed dormancy and interaction with endogenous hormones. In this review, we summarize current views of the molecular mechanisms by which light controls the induction, maintenance and release of seed dormancy, as well as seed germination, by regulating hormone metabolism and signaling pathways.

光照在调节种子休眠和萌发中的作用。

种子休眠是植物的适应性状。打破种子休眠决定了发芽的时间，因此对于确保植物存活和农业生产至关重要。种子的休眠和随后的发芽受内部线索（主要是激素）和环境信号的控制。在过去的几年中，已经发现了植物激素在调节种子休眠和萌发中的作用。但是，我们才刚刚开始了解光信号通路如何调节种子休眠以及与内源激素的相互作用。在这篇综述中，我们总结了分子机制的最新观点，其中光通过调节激素代谢和信号传导途径来控制种子休眠的诱导，维持和释放以及种子萌发。
