摘要
为了解有色稻米及其相关基因的研究进展,归纳了有色稻米的功能,分析了Ra、Rc、Rd、OsC1和OsB2基因对有色稻米性状的影响。这些基因通过影响花青素和原花青素的积累,决定了米粒的红、黑、紫等颜色。研究指出了相关稻米颜色基因在水稻育种中的局限性,目前的研究还不够系统,导致无法充分利用这些基因的多样性,也不能证明这些基因在水稻其他性状上的作用。笔者认为可以采用全基因组关联分析和群体遗传学方法,系统分析这些基因在不同水稻品种中的变异和表达模式,为水稻遗传改良提供数据支持,也可以利用遗传学方法和现代生物技术手段探索这些基因在水稻其他性状中的功能,为水稻的多性状改良提供理论依据。
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.
