Southern rice black-streaked dwarf virus (SRBSDV) is one of the most damaging rice viruses. The virus decreases rice quality and yield, and poses a serious threat to food security. From this perspective, this review performed a survey of published studies in recent years to understand the current status of SRBSDV and white-backed planthopper (WBPH, Sogatella furcifera) transmission processes in rice. Recent studies have shown that the interactions between viral virulence proteins and rice susceptibility factors shape the transmission of SRBSDV. Moreover, the transmission of SRBSDV is influenced by the interactions between viral virulence proteins and S. furcifera susceptibility factors. This review focused on the molecular mechanisms of key genes or proteins associated with SRBSDV infection in rice via the S. furcifera vector, and the host defense response mechanisms against viral infection. A sustainable control strategy using RNAi was summarized to address this pest. Finally, we also present a model for screening anti-SRBSDV inhibitors using viral proteins as targets. © 2023 Society of Chemical Industry.
南方水稻黑条矮缩病毒（SRBSDV）是危害水稻最严重的病毒之一。该病毒降低了稻米的品质和产量，对粮食安全构成了严重威胁。有鉴于此，本综述对近年来已发表的研究进行了调查，以了解 SRBSDV 及白背飞虱（WBPH，褐飞虱 Sogatella furcifera）在水稻中的传播过程的现状。最近的研究表明，病毒毒力蛋白与水稻易感性因子之间的相互作用决定了 SRBSDV 的传播。此外，病毒毒力蛋白与 S. furcifera 易感性因子之间的相互作用也影响了 SRBSDV 的传播。本综述重点介绍了通过褐飞虱介体感染水稻的与 SRBSDV 相关的关键基因或蛋白的分子机制，以及宿主对病毒感染的防御反应机制。总结了利用 RNAi 进行可持续控制的策略来解决这一害虫问题。最后，我们还提出了一个利用病毒蛋白作为靶标筛选抗 SRBSDV 抑制剂的模型。© 2023 英国化学学会。
