Comparative proteomic analysis provides new insights into cadmium accumulation in rice grain under cadmium stress

- Cd is the most toxic heavy metal and is a major pollutant in rice grains.
- The mechanism of Cd accumulation in rice grains has not been well demonstrated.
- Proteomics analysis is carried out and the verification is implemented by QPCR.
- Proteins associated with ROS and photosynthesis showed large variation in expression.
