摘 要:重金属污染是全球面临的重大环境污染问题之一。镉是植物生长发育非必需的微量元素,不仅影响植物生长发育,甚至会造成植物死亡,并且可通过在植物体内积累而威胁人类的生命健康。因此,植物对重金属镉的吸收是环境污染研究领域的一个热点问题。现主要从重金属镉对植物生长发育的影响及植物的抗氧化系统、不同类型转运蛋白家族等方面对植物耐受镉胁迫的机理进行综述,并对相关研究领域的一些重点问题进行了展望。
 
Research advances in the tolerance mechanism of plant response to heavy metal cadmium stress

Abstract: Heavy metal pollution is one of the major environmental pollution problems in the world. Cadmium is a non-essential heavy metal for plants. Soil and water pollution by cadmium is a serious environmental problem that inhibits plant growth and poses hazards to human health through the food chain. So the heavy metal cadmium uptake in plants is a hot topic in the research field of environmental pollution. In this article, we review recent progress on the tolerance mechanisms of plant response to cadmium stress, including the effects of cadmium on plant growth, plant antioxidant systems and different types of transport protein families. Some key issues in this research field are prospected in the end.
