中文摘要：

甜菜碱是植物重要的渗透调节物质,在低温等逆境条件下,许多植物细胞中迅速积累甜菜碱以维持细胞的渗透平衡。对近几年来甜菜碱提高植物抗寒性的机理研究及其应用,包括甜菜碱的生物合成途径、低温胁迫下甜菜碱对植物的保护机理、甜菜碱合成酶基因的转化及外源甜菜碱在植物抗寒中的应用进行了综述。

英文摘要：

Glycine betaine is an important osmotic regulator in plants. Many plant cells rapidly accumulate glycine betaine under adverse conditions, including low temperature to maintain an osmotic balance. This article provides an overview of the mechanism of improving cold resistance of plant by glycine betaine and its application, including glycine betaine biosynthesis, its protection mechanism under cold stress, the transformation of glycine betaine synthetase genes, and the effect of exogenous glycine betaine on improving cold resistance of plant.
