Abstract:

To understand the research progress of colored rice and its related genes, the functions of colored rice were summarized, and the effects of Ra, Rc, Rd, OsC1 and OsB2 genes on the traits of colored rice were analyzed. These genes determine the red, black, and purple colors of rice grains by influencing the accumulation of anthocyanins and proanthocyanidins. In this paper, we point out the limitations of related rice color genes in rice breeding. And the current research is not systematic enough to make full use of the diversity of these genes and prove the role of these genes in other rice traits. It is believed that genome-wide association analysis and population genetics method can be used to systematically analyze the variation and expression patterns of these genes in different rice varieties, and provide data support for rice genetic improvement. We can also use genetic methods and modern biotechnology methods to explore the functions of these genes in other traits of rice, to provide theoretical basis for the improvement of multiple traits of rice.
