| 摘 要： | 低温是影响植物生长发育和植被分布的一种非生物胁迫。当环境温度持续低于植物生长的最佳温度时即形成低温胁迫,包括冷害和冻害。冷害是指零度及以上低温对植物造成的伤害,细胞内不结冰,但会使喜温类植物产生生理性障碍,引起该类植物受伤或死亡。冻害是指零度以下低温对细胞造成损伤甚至死亡的现象。植物从感知低温到功能基因表达,进而抵御低温胁迫,相关调控机制一直是研究热点。本文综述了近年来植物低温胁迫相关研究,从信号感知、信号传导、功能基因表达、低温诱导的生理和细胞调机制等几个方面进行了分析讨论,并对植物抗寒研究做出展望,这将有助于抗寒植物新种质的培育。

| Abstract: | Low temperature is an abiotic stress that could affect plant growth and vegetation distribution. Once the environmental temperature is continuously lower than the optimal temperature for plant growth, the plant would suffer low temperature stress, including chilling injury and freezing injury. Chilling injury refers to the damage on plant caused by low temperature of zero degree or above. The cells do not freeze at this temperature, but the cold will have physiological obstacles for thermophilic plants, causing injury or death. Freezing damage refers to the phenomenon that plants are damaged or die because of the low temperature below the freezing point. Previous studies mainly focused on the regulation mechanism of low temperature stress on plants, including the process in plants from the perception of low temperature signal to the expression of functional genes, and to the resistance to low temperature stress. This article reviews the research on cold stress on plants in recent years, analyzes the research status from the aspects of signal perception, signal transduction, functional gene expression, cold-induced physiological and cellular regulatory mechanism, and discusses the prospect of the research on plant cold resistance. It will provide a theoretical basis for cultivating new cold-resistant plant germplasms. |
