水稻稻瘟病抗性基因挖掘与利用研究进展

Research Progress in Mining and Utilization of Rice Blast Resistance Genes

稻瘟病是一种由子囊菌(Magnaportheoryzae)引起的病害,严重危害水稻的产量和品质。培育和种植抗病品种是控制稻瘟病最经济有效的措施。抗性基因的挖掘与利用是培育抗病品种的基础和关键。本文针对这个科学问题,总结了目前主流的稻瘟病抗性基因的挖掘技术,对已克隆的稻瘟病抗性基因及其应用现状进行梳理和分析;并对稻瘟病抗性基因挖掘利用以及未来发展方向进行展望。

Rice blast is a disease caused by Magnaporthe oryzae,which seriously threatens the yield and quality of rice.At present,breeding disease-resistant varieties is the most economical and effective way to control rice blast,and identifying resistance genes is the key to disease-resistant variety breeding.The review summarized the types of rice blast resistance genes cloned as well as the current mainstream techniques for identifying blast-resistant genes.The application of these genes has been outlined along with future development directions.
