摘要
简要综述了光敏色素的分子特性、亚细胞定位、感光性和它介导的光信号传导及调控作用等方面的研究进展。指出光敏色素是一种调节植物许多光反应的色素蛋白复合体,不同的光敏色素具有特异的亚细胞定位和感光性。光敏色素家族介导的光信号传导构成了一个复杂的网络系统。同时,还讨论了拟南芥光敏色素家族的研究成果。
Plants have developed multiple photoreceptors to sense and respond to the changes in the light environment. Recent advances in elucidating the properties, subcellular localization, photoperception and signal transduction of phytochromes were briefly described in this review. Phytochrome is a chromoprotein that regulates many light responses in plants. Individual phytochromes have specific subcellular localization and photoperception. Phytochrome-mediated signal transduction constitutes a complicated signaling cascade. The advances of researches on phytochromes in Arabidopsis thaliana were also discussed.
