摘要:

水稻(Oryza sativa L.)是我国重要的粮食作物,其生长发育过程经常受到稻瘟病的威胁,严重时导致巨大的经济损失。挖掘和利用水稻稻瘟病抗性基因,培育具有广谱抗性的优良品种是目前防治稻瘟病最经济有效的方法。稻瘟病抗性基因一般为编码含有核苷酸结合结构域(nucleotide-binding,NB)和富含亮氨酸重复结构域(leucine-rich repeat,LRR)的基因家族,也被叫做NLR基因,在水稻抗稻瘟病方面发挥至关重要的作用。因此,对NLR基因的挖掘以及阐明其与对应效应因子之间的识别和激活机制,对于培育抗病品种具有重要意义。本文对水稻中NLR基因的挖掘概况、NLR蛋白与稻瘟病菌效应因子之间的识别方式,以及成对NLR蛋白作用机制进行了总结和展望,旨在为水稻抗病育种提供参考。

Abstract:

Rice (Oryza sativa L.) is an important food crop in China. Its growth and development are threatened by rice blast, which leads to huge grain losses in severe cases. Cultivating and deploying rice varieties that contain broad-spectrum resistance (R) genes is the most economical and effective strategy to prevent and control rice blast. In general, rice blast resistance genes code nucleotide-binding (NB), leucine-rich repeat (LRR) receptors (NLRs) that play a crucial role in the resistance to rice blast. Therefore, it is essential to clone NLR genes and elucidate the recognition and activation mechanisms between NLRs and effectors for rice disease resistance breeding. In this review, we summarize and provide perspectives on the research progress of NLR genes, the recognition between NLR proteins and effectors in rice, as well as the role and mechanism of paired NLR proteins in the resistance, hoping to provide reference for rice disease resistance breeding.

Key words: rice, rice blast, NLR gene, resistance, resistance breeding
