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
