植物感知和传递低温信号的分子机制
Molecular Mechanism of Cold Signal Perception and Transduction in Plants
摘要
Abstract
Cold stress is an important environmental stress affecting plant growth,development and crop productivity.Plants sense the low temperature signal and quickly initiate the low temperature response to reduce the damage caused by low temperature stress.Recent studies have revealed the low-temperature potential sensors and complex regulatory network in plant cold stress responses.Plants may perceive cold signal at multiple levels;however,the detailed mechanisms remain unclear.Cold-induced second messengers such as Ca2+ signal and ROS are decoded,thereby activating the expressions of cold-responded genes.Moreover,protein post-translational modifications(PTMs)regulate protein activity and stability and play critical roles in early cold signal transduction in plants.Here,we focus on the molecular mechanism of plant perception and transmission of low temperature early signals,and discusses and looks forward to the challenges and research directions in the field of low temperature stress.关键词
