摘　　要：光对植物的生长发育具有重要的调控作用,植物具有极其精细的光感受系统。植物的光受体作为接受光的蛋白质,调控着高等植物的许多分子、细胞及发育反应。目前已知至少存在5类光受体:光敏色素、隐花色素、向光素、ZTLs家族和UV-B受体。主要综述植物光受体的结构、理化性质、生物学功能、信号转导及其分子生物学研究进展,探讨光受体之间及信号转导在植物发育中的作用及光诱发植物作出反应的分子机制。The light plays important roles in plants growth and development.Plants have an extremely elaborate photoreceptor system.Plant photoreceptors,as the protein receiving light,regulate many plant mechanisms such as molecular,cellular and developmental response.There are at least 5 types of light receptors including phytochrome,cryptochrome,phototropin,zeitlupes and UV-B receptors.The light receptors of construction,physical and chemical properties,biological functions,signal transduction and the research progress of molecular biology were reviewed and the functions of light receptors and signal transduction in plant development and their molecular mechanisms were discussed in this paper
