Research progress in studying molecular physiological mechanisms of low Cd accumulation in rice grain

With sustained rapid development of the national economy, heavy metal pollution of farmland ecosystem is becoming more serious. Cd is active transport in the environment, and has large toxicity to organism and human. Rice is the major source of food for chinese, while rice has a strong absorption capacity of Cd, and thus rice security has become an issue of concern. This paper reviewed the research progress on molecular physiological mechanisms of low-Cd rice grain in recent years.
