摘 要: 水稻齿叶矮缩病毒(rice ragged stunt virus,RRSV)是水稻齿叶矮缩病的病原,也是重要的水稻病毒之一,它隶属于呼肠孤病毒科(Reoviridae)水稻病毒属(Oryzavirus),是该属的典型成员,由介体褐飞虱(Nilaparvata lugens)(brown planthopper,BPH)以持久增殖型方式传播,它既能在宿主水稻中繁殖,也能在媒介昆虫体内繁殖。该病毒结构具有双层蛋白外壳,表面有刺突蛋白,有10条双链RNA(double strand RNA,dsRNA)基因组片段,是双链RNA病毒。围绕近年来国内外有关RRSV的研究进展,这里综述了RRSV病毒自身特性,包括病毒粒子、基因组、蛋白组结构功能,RRSV介体褐飞虱特性以及防治措施,并提出了RRSV研究过程中涉及的一些问题。

Abstract: Rice ragged stunt virus (RRSV) is a pathogen of rice ragged stunt disease, one of the most serious viral diseases of rice. RRSV is a well-established Oryzavirus species in the family Reaviridae. It is transmitted by brown planthopper (BPH) Nilaparvata lugens, also in a persistent propagative manner and can replicate in both host of rice and insect vector. RRSV has a complex multi-component particle bearing spike on its outer surface and its genome contains 10 segments of double strand RNA (dsRNA). In this review, we summarized recent findings on RRSV research, especially focused on viral characteristic, such as virion, viral genome, viral proteins, BPH characteristics and the control measures of this disease and some problems that encountered during studies of RRSV proposed.
Key words: phytopathology; rice ragged stunt virus; review; Nilaparvata lugens; double strand RNA; control measures
