摘 要: 光敏色素是植物感受外界环境变化的最重要光受体之一,对红光和远红外光非常敏感。本文综述了光敏色素的分子结构、它所包含的结构域和相应功能以及植物各主要类群中光敏色素基因家族的成员组成与进化关系;重点在分子水平上介绍了光敏色素的生理功能与作用机制。最后,基于最新的研究进展提出了将来的研究方向。 The phytochrome molecule is the photoreceptor used by plants to sense environmental red and far-red light changes, which are vital to direct growth and development. In this review, we present (1) the chromoprotein structure of phytochrome, its domains and corresponding functions; (2) members of phytochrome gene families and their evolutionary relationships in the main groups of plants; (3) advances in molecular mechanisms of phytochrome signaling and gene regulation; and (4) prospects for future research.
