摘　　要：植物在适应低温胁迫的过程中,体内将会发生一系列生理生化反应,多种基因得以诱导表达,这些基因的表达在时空上是有序发生的,并相互联系形成了低温应答的分子机制。为促进我国桑树抗寒分子育种的研究,结合植物的抗冻特性和桑树低温胁迫反应,对植物的3种主要低温诱导蛋白(抗冻蛋白、胚胎后期富集蛋白和转录因子)的研究进展进行了综述,并以此阐述了植物抗寒抗冻特性和植物低温应答的分子机制。The procedure of plant adapting the low temperature stress can induce a series of physiologic and biochemical responses, and expression of some genes are also induced, such as antifreeze protein genes, late-embryogenesis-abundant protein genes and transcription factor genes. Expression of these genes are sequential and interdependent, thus they form the molecular mechanism of low temperature responses. In order to improve the mulberry molecular breeding technique, three major low temperature induced proteins of plant mentioned above were summarized in this paper. Meanwhile, we narrate the molecular mechanism of the cold and freeze resistance characteristics of plant.
