摘要
水稻氮素利用效率的高低直接影响水稻产量以及生态环境。在水稻氮素利用相关基因的研究中,研究人员通过连锁作图和关联作图等方法克隆基因,并解析水稻的氮素利用机理,为水稻氮素高效利用育种提供了基因资源。本文从水稻氮素利用QTL定位及基因克隆,基于全基因组关联分析的水稻氮素利用相关基因克隆,利用突变体克隆水稻氮素利用相关基因,利用反向遗传学克隆水稻氮素利用相关基因等方面总结了近年水稻氮素利用相关基因的研究进展。同时对该领域的未来研究进行了展望。本文为水稻氮素高效利用基因的研究和氮素高效利用育种提供了参考。
Nitrogen use efficiency(Nue)of rice directly affects rice yield and ecological environment.In the research of rice nitrogen use-related genes,researchers cloned the genes by means of linkage mapping and association mapping,and analyzed the mechanism of rice nitrogen utilization,which provided genetic resources for rice nitrogen efficient utilization breeding.This article summarized the research progress of rice nitrogen utilization related genes in recent years,including QTL mapping and gene cloning of rice nitrogen utilization,cloning of rice nitrogen utilization related genes based on whole genome association analysis,cloning of rice nitrogen utilization related genes using mutants,and cloning of rice nitrogen utilization related genes using reverse genetics.At the same time,the future research in this field was prospected.This paper provides a reference for the research of nitrogen efficient utilization genes and nitrogen efficient utilization breeding in rice.
