水稻条纹病毒（Rice Stripe Virus，RSV）是危害水稻最严重的病毒之一，在中国、日本和韩国等主要种植粳稻的国家，RSV的危害严重影响水稻产量。RSV通过小褐飞虱（SBPH）以持久和循环繁殖的方式传播。已经开发了几种用于检测RSV的方法，RSV由编码七种蛋白质的四种单链RNA组成。基因组序列数据和比较系统发育分析已被用来确定RSV分离株的起源和多样性。目前已筛选出多个抗RSV的水稻品种，并进行了QTL分析和精细定位，以定位RSV抗性位点或基因。RSV基因已经被用于产生几种具有RSV抗性的遗传修饰的转基因水稻植物。最近，全基因组转录组分析和深度测序已被用于鉴定参与RSV感染的mRNA和小RNA;还鉴定了与RSV蛋白相互作用的几种水稻宿主因子。本文综述了RSV的研究现状，并提出了研究RSV、水稻和SBPH相互作用的综合方法。
Rice stripe virus (RSV) is one of the most destructive viruses of rice, and greatly reduces rice production in China, Japan, and Korea, where mostly japonica cultivars of rice are grown. RSV is transmitted by the small brown plant-hopper (SBPH) in a persistent and circulative-propagative manner. Several methods have been developed for detection of RSV, which is composed of four single-stranded RNAs that encode seven proteins. Genome sequence data and comparative phylogenetic analysis have been used to identify the origin and diversity of RSV isolates. Several rice varieties resistant to RSV have been selected and QTL analysis and fine mapping have been intensively performed to map RSV resistance loci or genes. RSV genes have been used to generate several genetically modified transgenic rice plants with RSV resistance. Recently, genome-wide transcriptome analyses and deep sequencing have been used to identify mRNAs and small RNAs involved in RSV infection; several rice host factors that interact with RSV proteins have also been identified. In this article, we review the current statues of RSV research and propose integrated approaches for the study of interactions among RSV, rice, and the SBPH.
