Abstract: Selenium (Se) is an essential element for animals and human. It could remove free radicals in plants, improve the yield and quality of crops, and mitigate heavy metal stress and accumulation. This paper investigated the effects of Se on cadmium (Cd) uptake and translocation in different plant species, and summarized mechanisms involved with Se for mitigation of Cd stress, which was expected to provide references for developing strategies for reducing Cd accumulation in agricultural products.

Key words: selenium, cadmium, uptake, translocation, mitigation
