中文摘要:
      南方水稻黑条矮缩病(Souther rice black-streaked dwarf virus disease, SRBSDVD)是依靠白背飞虱(Sogatella furcifera)为传播介体,由南方水稻黑条矮缩病毒(Southern rice black-streaked dwarf virus,SRBSDV)侵染引起的一种水稻病毒病。该病害于 2001 年在我国华南地区首次被发现,随后发生面积不断扩大,危害逐年加重,已成为近年来危害中国南方稻区水稻生产的重要病害之一。白背飞虱迁飞性强、种群数量大、传毒持久等特点,导致化学农药防虫治病效果并不理想,至今还未有可持续和绿色控制 SRBSDVD 的手段。根据病原病毒的爆发性及其传播介体白背飞虱的生物学特性,预计该病害在未来较长的一段时期内将是我国最严重的水稻病害之一,很有可能再次暴发流行。因此,当前生产上急需培育出能够抵御 SRBSDVD 的抗性水稻品种。本文综述了 SRBSDVD 的发病规律、抗病种质资源的收集与评估、抗病基因或数量性状位点(QTL)的精确定位,以及这些抗性基因的分子作用机制,进一步探讨了利用现代分子生物学技术,包括分子标记辅助选择、基因沉默(RNAi)和基因编辑等技术加快 SRBSDVD 抗病品种的选育,可为今后有效控制 SRBSDVD 提供基础。
英文摘要:
      Southern rice black-streaked dwarf virus disease (SRBSDVD), which is transmitted by the Sogatella furcifera and caused by the infection of southern rice black-streaked dwarf virus (SRBSDV). The disease was first discovered in southern China in 2001 and has since spread, causing increasing damage to rice production in southern China. And it has been one of the main diseases damaging rice production in southern China. Due to the strong migratory ability, large population and persistent transmission of the white-backed planthopper, chemical pesticides have proven to be ineffective in pest and disease control. So far, there is no sustainable and environmentally friendly means to control this disease. Based on the outbreak of the pathogenic virus and the biological characteristics of its vector, the white-backed planthopper, it is expected that the disease will be one of the most serious rice diseases in China for a long period of time in the future, and there is a high likelihood of outbreak of epidemics. Therefore, there is an urgent need to breed resistant rice varieties that can withstand SRBSDVD. In this review, we summarize the pathogenicity of SRBSDVD, collection and evaluation of resistant germplasm resources, the precise positioning of resistance genes/QTLs, and the molecular mechanisms of resistance genes. In addition, the study further explores the use of modern molecular biological techniques, including molecular marker-assisted selection, gene silencing (RNAi) and gene editing, to accelerate the selection and breeding of disease-resistant varieties of SRBSDVD, which will provide a basis for effective control of SRBSDVD in the future.
