Application of CRISPR/Cas9 Technology in the Genetic Improvement of Rice Yield and Quality Characters

Abstract

Rice (Oryza sativa L.) is one of the most important food crops in the world. With the continuous increase of global population and the continuous improvement of people's living standards, it has become the focus of attention of rice breeders and botanists to improve the yield and quality of rice. In the new genome editing technology, the CRISPR/Cas system can accurately and specifically edit the target genome region. In recent years, CRISPR/Cas9 technology has made important progress in studying the function of new genes, increasing rice yield and improving rice quality. Therefore, this paper mainly reviewed the application of CRISPR/Cas9 technology in the genetic improvement of rice yield and rice quality in recent years, and looked forward to the application prospect of CRISPR/Cas9 technology in rice genetic breeding, which will provide important reference for the cultivation of new high-quality and high-yield rice varieties.
