| Abstract: | Cadmium （Cd） is an important soil pollutants and easily absorbed by rice. Excess Cd inhibits the growth and development of rice. Selecting Cd tolerance cultivars has become an important topic in the current rice breeding program. This paper has reviewed the effect of Cd stress on growth and development of rice,agronomic traits,physiological and biochemical characteristics,the Cd tolerant mechanism of physiology and biochemistry and genetic mechanisms and progress in molecular biology research of Cd stress. It also has put forwards some suggestions for the future researches of Cd tolerance of rice. |
