[Abstract]  Rice black-streaked dwarf virus (RBSDV), a member of genus Fijivirus in the family Reoviridae, infects rice, maize, barley and wheat, and can seriously affect crop yields. RBSDV is transmitted by the small brown planthopper (Laodelphax striatellus, SBPH) in a persistent manner. RBSDV has 10 linear dsRNA genomic segments, making it difficult to construct infectious clones for functional studies in plants. Here we describe a method for inoculating and maintaining RBSDV on rice in a greenhouse for use in laboratory research. The protocol uses SBPHs mass reared in the laboratory. We also describe in detail the propagation of a healthy planthopper population, the preparation of plant material, RBSDV inoculation and the evaluation of the rice after inoculation. [摘要]  水稻黑条矮缩病毒(RBSDV)属于呼肠孤病毒科的Fijivirus属的成员,感染水稻,玉米,大麦和小麦,可严重影响作物产量。 RBSDV以持久的方式由小型褐飞虱( Ladellphax striatellus ,SBPH)传播。 RBSDV具有10个线性dsRNA基因组区段,使得构建用于植物功能研究的感染性克隆变得困难。 在这里我们介绍一种在温室中用于在实验室研究中使用的RBSDV接种和维持方法。 该协议使用在实验室饲养的大量的SBPHs。 我们还详细描述了一个健康的稻飞虱种群的繁殖,植物材料的制备,RBSDV接种和接种后水稻的评价。

【背景】水稻黑条矮缩病毒(RBSDV)是Fijivirus属家族中的第二个家族中的公认成员,严重影响东亚水稻和玉米的生产。 (Shikata和Kitagawa,1977; Zhang等人,2001a)。 RBSDV以持续的方式(Shikata和Kitagawa,1977)被小型褐飞虱(灰飞虱,SBPH)传播传播到水稻,玉米,大麦和小麦。 SBPH可从新鲜或冷冻感染的水稻叶片获得RBSDV并将其传递至健康植物(Shikata和Kitagawa,1977; Li等人,2010)。一旦SBPH已经获得病毒,病毒可以在昆虫载体中繁殖,并且可以在昆虫的整个生命周期中传播给宿主植物。然而,SBPH不能透传病毒(Boccardo and ...
