| Abstract: | Starch, storage proteins and lipids are the main nutritious substances in rice seeds, and the composition and content in seeds play a decisive role in the grain quality of rice. This review mainly summarized the new advances in the synthesis, the related genes expression and regulation of main nutritious substances such as starch, storage proteins, lipids and amino acids in rice seeds. In addition, the challenges of the nutritious substances in rice genetic improvement were also discussed. This review would provide an important reference for genetic improvement of grain quality and the cultivation of new varieties in rice. |
