摘　　要：金属硫蛋白(metallothionein,MT)是一种低分子量、富含半胱氨酸的非酶类金属结合蛋白,广泛存在于生物体内。植物金属硫蛋白基因在多种非生物胁迫下诱导表达,增强植物耐受性和抗逆能力。本文综述了植物金属硫蛋白在重金属、盐、高温、干旱、氧化等非生物胁迫下的基因表达调控及其功能,为深入研究植物金属硫蛋白在逆境条件下的生物学功能提供参考。Metallothionein(MT)is a low molecular weight,cysteine rich,non enzymatic metal binding protein,which widely exists in organisms.Plant metallothionein genes expression were induced under various abiotic stresses,and the resistance of plants were enhanced.In this paper,the gene expression regulation and function of plant metallothionein under abiotic stress such as heavy metal,salt,high temperature,drought and oxidation were reviewed,some scientific issues of the plant metallothionein genes biological function will be investigated under stress conditions in the future.
