植物病原真菌与真菌病毒的互作在生态系统中扮演着重要角色。研究表明，弱毒真菌病毒能够显著降低植物致病真菌的毒力和侵染能力。部分病原真菌在病毒感染后，甚至可以转化为对植物有益的内生真菌。因此，利用弱毒真菌病毒作为生 物防治剂已成为控制植物真菌病害的一种新兴且有应用潜力的策略。近年来，随着环境采样和分子生物学技术的飞速发展，真菌病毒的研究已取得显著进展，尤其在病毒、真菌与植物之间的复杂相互作用方面。本文综述了植物-真菌-病毒相互作用的研究进展，并探讨了该领域在植物病害防治中的应用前景。

 The interaction between plant pathogenic fungi and mycoviruses plays a significant role in ecosystems. Weakly virulent mycoviruses can significantly reduce the virulence and infectivity of plant pathogenic fungi. In some cases, fungal pathogens can even transform into beneficial endophytic fungi after viral infection. As a result, using weakly virulent mycoviruses as biocontrol agents become an emerging and promising strategy for controlling plant fungal diseases. In recent years, with the rapid development of environmental sampling and molecular biology techniques, research on mycoviruses has made significant progress, especially regarding the complex interactions among viruses, fungi, and plants. This review provides a comprehensive analysis of the research progress on plant-fungus-virus interactions and looks forward to the potential applications of this field in plant disease management.
