Abstract

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.

分枝病毒及其对真菌的生态影响

作为菌丝内微生物组的组成部分，分枝病毒已在主要的真菌和卵菌群中被广泛鉴定。虽然大多数分枝病毒感染是无症状的，但相当多的分枝病毒会显著影响其宿主的生物学特性。本文综述了真菌病毒在宿主真菌和卵菌的生态适应中的作用。传统观点认为，分枝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之间水平传播。然而，最近的研究记录了分枝病毒在物种之间传播的实例，甚至跨越不同的王国，以及通过特定的载体，这表明存在其他传播途径。虽然大多数分枝病毒对宿主表型影响很小或没有影响，但某些分枝病毒感染可以显著影响宿主的适应性。值得注意的是，最近的研究表明，分枝病毒可以改变真菌和植物之间的相互作用。这些发现可能为应用分枝病毒管理真菌和卵菌引起的植物病害提供创新策略。

期刊介绍： Launched in 1955, Virology is a broad and inclusive journal that welcomes submissions on all aspects of virology including plant, animal, microbial and human viruses. The journal publishes basic research as well as pre-clinical and clinical studies of vaccines, anti-viral drugs and their development, anti-viral therapies, and computational studies of virus infections. Any submission that is of broad interest to the community of virologists/vaccinologists and reporting scientifically accurate and valuable research will be considered for publication, including negative findings and multidisciplinary work.Virology is open to reviews, research manuscripts, short communication, registered reports as well as follow-up manuscripts.
