植物在冷驯化过程中,以CBFs(C-repeat binding factor)为调控核心,通过调节冷相关基因的表达而提高抗冷能力。植物应答低温的部分基因还受到光的调节,同时冬性作物与春性作物不同,冬性作物在冷驯化提高抗冷性的同时光合作用、株型等发生协同变化,体现了植物冷驯化机制的复杂性。本文主要综述冬春性作物冷驯化中光合作用和株型表现的研究进展,总结温度和光复杂信号的感知与转导途径,为植物冷驯化机理研究及作物耐冷育种提供参考。
During the process of cold acclimation, plants take C-repeat binding factor (CBFs) as the core of regulation, and improve cold resistance by regulating the expression of cold-related genes. Some genes that plants respond to low temperature are also regulated by light, and winter crops are different from spring crops. Winter crops are cold acclimation to improve cold resistance, photosynthesis, plant type and other changes occur synergistically, which reflects the mechanism of plant cold acclimation Complexity. This review summarizes the research progress of photosynthesis and plant type in cold acclimation of winter and spring crops, summarizes the sensing and transduction pathways of temperature and light complex signals, and provides references for cold acclimation mechanism and cold tolerance breeding of crops.
