Abstract: The protein content is one of the main indices determining the rice nutrition value. Improving protein content is an important target for nutrition quality breeding in rice. This paper described the protein type, amino acid’s constitute and the nutrition value in rice. Meanwhile the paper summarized the difference among genotypes of rice and different parts of brown rice, the genetic and molecular mechanism research on the protein content, which will provide a basis for the protein research and breeding of hig
