植物耐镉机制研究进展

Research Progress on Mechanisms of Plant Resistance to Cadmium

重金属镉不仅影响植物的生长发育,而且对人体也有毒害作用。综述了近年来重金属镉离子对植物的毒害及植物耐镉性机制等方面的研究进展,主要包括金属镉离子对植物的影响,植物吸收镉离子的影响因素,镉离子在植物体内的运输途径,植物抵抗镉毒害的防御方式及植物耐镉基因等。

Heavy metal cadmium affects on not only the growth and development of plants,but also human. This paper re-viewed the research progresses on toxicity of cadmium on plants and mechanism of plants tolerance to cadmium,including the effect of cadmium on plants,influence factors of plant uptake to cadmium,transportation pathways of cadmium in plants,the ways of plant resistance to cadmium,the tolerance gene of plants to cadmium,and so on.
