Mycoviruses, as components of the endohyphal microbiome, have been extensively identified in major fungal and oomycetous groups. While most mycoviral infections are asymptomatic, quite a few mycoviruses significantly affect biological characteristics of their hosts. This review emphasizes the roles of mycoviruses in the ecological adaptation of host fungi and oomycetes. Traditional views suggest that mycoviruses are primarily transmitted vertically through spores or horizontally among different individuals via hyphal fusion or anastomosis. However, recent studies have documented instances of mycoviral transmission between species, even across different kingdoms, as well as through specific vectors, suggesting the presence of additional transmission pathways. Although the majority of mycoviruses exert little to no influence on host phenotypes, certain mycoviral infections can significantly impact host fitness. Notably, recent research indicates that mycoviruses can alter interactions between fungi and plants. These findings may offer innovative strategies for the application of mycoviruses in management of plant diseases caused by fungi and oomycetes.
作为菌丝内微生物群的组成部分，真菌病毒已在主要的真菌和卵菌群体中被广泛鉴定。虽然大多数真菌病毒感染是无症状的，但相当多的真菌病毒会显著影响其宿主的生物学特性。本综述强调了真菌病毒在宿主真菌和卵菌生态适应中的作用。传统观点认为，真菌病毒主要通过孢子垂直传播，或通过菌丝融合或吻合在不同个体间水平传播。然而，最近的研究记录了真菌病毒在物种间甚至不同界之间的传播实例，以及通过特定载体的传播，这表明存在其他传播途径。尽管大多数真菌病毒对宿主表型影响很小或没有影响，但某些真菌病毒感染可显著影响宿主适应性。值得注意的是，最近的研究表明，真菌病毒可改变真菌与植物之间的相互作用。这些发现可能为真菌病毒在防治由真菌和卵菌引起的植物病害中的应用提供创新策略。
