摘要: 水稻是世界上最主要的粮食作物之一,其产量的稳定性直接关系到粮食安全和社会稳定。然而,自20世纪中叶起,由介体昆虫飞虱、叶蝉等传播的各种水稻病毒病的爆发,严重威胁着水稻产量。水稻草矮病(Rice grassy stunt disease,RGSV)由介体昆虫褐飞虱(Nilarparvata lugens)以持久增殖型方式传播,被病毒感染的水稻呈现植株矮化,分蘖增多,叶片黄化且带有锈斑等典型病害症状。围绕近年国内外关于RGSV的研究进展,本文对病毒粒子特性、常用检测方法、基因组结构及功能、症状形成机制探索和防治策略等方面进行了综述,并提出了RGSV研究过程中所涉及到的一些问题,以期为开展RGSV相关研究提供参考。

Abstract: Rice(Oryza sativa)is an uppermost food crop in the world,and the stability of rice production directly affects food security and social stability. Since the middle of the last century,however,rice production is frequently threatened by various kinds of rice viruses that are transmitted by insect vectors such as planthopper,leafhopper,etc. Rice grassy stunt virus(RGSV)is transmitted by small brown planthoppers(Nilaparvata lugens)in a circulative and propagative manner. The infected rice plants present typical disease symptoms such as stuntedness,excess tillering,and leaf yellowing with rusty spot. Based on the advances of studying RGSV in both domestic and abroad,this paper mainly summarized viral characteristic,common virus detection methods,genomic structure and function,exploration for mechanisms of symptom induction,and measures for controlling rice grassy stunt disease,and finally pointed out the issues in studying RGSV. In order to provide reference for the research of RGSV.

Key words: rice grassy stunt virus, mechanism of symptom formation, control measures
