Abstract: Heavy metal pollution has caused great negative impact on China’s economic development and human health,which has became a hotspot of study. This paper reviewed the research progresses on toxicity of heavy metal on plants and mechanism of plants tolerance,including the effect of metal on plants growth and development,the ways of plant resistance on toxicity of heavy metal,the tolerance gene and protein of plants to heavy metal,and so on,existing problem and major topics of future research were also disussed.

Key words: heavy metal, plants, tolerance, molecular mechanism
