| 英文摘要 | Begomoviruses (Family Geminiviridae), the largest genus of plant viruses with single stranded circular DNA, could infect large range of plants including grasses, solanaceae, Malvaceae, Cruciferae, legumes and other crops. Begomoviruses are insect vector whitefly (Bemisia tabaci ) transmitted plant viruses, causing devastating damage to crop production around the world. So far there is no efficient optionally available antiviral drugs, mainly due to the narrow resistance spectrum, and fast viral genome variation of geminivirus, the mutualism between geminivirus and their insects. In the field crop protection, it mainly rely on the use of chemical pesticides to kill whiteflies for prevention and control. However, problems such as insecticide resistance, environment pollution and food safety appeal for efficient and environmental safe drugs against whitefly transmitted geminivirus. The study is aimed to establish a high-throughput platform for screening natural compounds against Bemisia tabaci transmitted geminivirus, from traditional Chinese medicine, and further analyze the mechanism of action of antiviral compounds. A broad spectrum of anti-arboviruses natural products were obtained in our study, and the preliminary resistance mechanism of GSX3 as a plant immune agonist activation MKK2 were also illustrated. These results provided a new prodrug to establish effective prevention and control method for geminvirus, which would further resolve the plant broad-spectrum resistance to laid a solid foundation, new molecular targets for the broad spectrum of arboviruses by gene editing or molecular breeding. |
