作物病毒病灾变机制与可持续防控技术研究进展OA

Approximately 80％of plant viruses worldwide rely on insect vectors for transmission,and their frequent outbreaks and epidemics pose a serious threat to national food security and the sustainable development of agriculture in China.The emergence and spread of these diseases are critically dependent on the tripartite interactions among viruses,insect vectors,and host plants.This review systematically summarizes key advances from two National Key R&D Program projects(2022-2025):"Mechanisms of Crop Viral Disease Epidemics and Sustainable Control Technologies"and"Mechanisms of Vector Salivary Gland-derived Small RNAs Regulating Cross-kingdom Transmission of Plant Viruses."We focus on four core areas:molecular mechanisms of vector-mediated virus transmission,viral pathogenesis and crops host resistance mechanisms,emerging technologies for sustainable disease control,as well as research prospects and future directions.This review aims to provide a theoretical foundation and technical support for developing an intelligent,precise,and eco-friendly integrated management system to control crop viral diseases,thereby safeguarding the secure production of staple crops including rice and wheat and supporting China's national strategies for food security and biosecurity.
