摘要
光敏色素是红光和远红光受体,不但在植物光形态建成中扮演着重要的角色,还参与调控植物抗逆信号通路。阐述了光敏色素及其互作的转录因子通过诱导植物激素信号途径调控植物对病原菌、害虫等生物胁迫的反应及作用机制,以及光敏色素调控植物对临近植物的竞争胁迫、干旱、低温、高温等非生物胁迫反应的作用机制研究进展,并讨论与展望了光敏色素研究领域所面临的挑战与发展方向。
Phytochrome is a red and far-red light receptor,which not only plays an important role in plant morphogenesis,but also isinvolved in the regulation of plant defense resistance signaling pathway. Here,we present the reaction and mechanism of phytochrome and itsinteracted transcription factors regulating plant resistance to biotic stress,such as pathogens and pest,by inducing plant hormone signalingpathways. And we also review the mechanisms of phytochrome regulating abiotic stress,such as the competition of neighboring plants,drought,low temperature and high temperature. In addition,we discuss and prospect the challenges and future directions in the research ofphytochrome.
