摘  要:
低温冻害使许多植物生存受到严重危害,全球每年因低温冻害造成的农作物损失高达数千亿元。研究并提高植物抗冻性具有重要理论和现实意义。目前,通过对冷诱导基因、CBF、ICE、抗冻蛋白基因、脂肪酸去饱和酶基因、脯氨酸基因、SOD基因等与抗冻相关的基因的研究表明,将这些抗冻相关基因进行转基因,可以提高植物的抗冻性。现综述植物抗冻性基因的类型及其抗冻转基因植物最新研究进展。

摘  要:
The low temperature freeze injuries have done several harm to the plant survival and caused great losses to many crops yields.So,it has important theoretical and practical significance to study and improve the plant freezing resistance.At present,people has carried out widespread research on the COR,CBF,ICE,AFP genes,fatty acid desaturase genes,proline genes,SOD genes,furthermore people has worked out the relations between these genes and freezing tolerance.It turned out to prove to improve the freezing tolerance for plant by carrying out transgenic for plant with these relevant genes.This paper overviewed recent research of plant freezing resistance gene and antifreeze transgenic plants.
