Plants depend on the surrounding light environment to direct their growth. Blue light (300-500 nm) in particular acts to promote a wide variety of photomorphogenic responses including seedling establishment, phototropism and circadian clock regulation. Several different classes of flavin-based photoreceptors have been identified that mediate the effects of blue light in the dicotyledonous genetic model Arabidopsis thaliana. These include the cryptochromes, the phototropins and members of the Zeitlupe family. In this review, we discuss recent advances, which contribute to our understanding of how these photosensory systems are activated by blue light and how they initiate signaling to regulate diverse aspects of plant development.
植物依靠周围的光照环境来引导其生长。特别是蓝光（300 - 500纳米），它能促进多种光形态建成反应，包括幼苗形成、向光性和生物钟调节。在双子叶植物遗传模型拟南芥中，已鉴定出几种不同类型的基于黄素的光感受器，它们介导蓝光的作用。这些包括隐花色素、向光素和zeitlupe家族成员。在这篇综述中，我们讨论了最近的进展，这些进展有助于我们理解这些光感系统是如何被蓝光激活的，以及它们如何启动信号传导来调节植物发育的各个方面。
