Expression Regulation of Starch and Storage Protein Synthesis Related Genes in Rice Grains

Starch and the storage proteins are the main nutritious substances in crop grains, and their composition and content in grains play a decisive role in the grain quality of rice and other staple food crops. This review has mainly summarized the new advances in the expression regulation of starch and storage protein synthesis related genes in rice grains. Moreover, the challenges of the starch and storage protein synthesis substances in rice genetic improvement were also discussed. This review will provide important information for genetic improvement of grain quality in rice and, potentially, other staple cereals.
