异担子属由几种死体营养和腐生真菌组成，包括一些北方针叶林中最有害的生物。这些真菌拥有广泛且多样化的真菌病毒群落，由超过 16 种分枝病毒科、一种纳纳病毒科和一种与弯孢热耐受病毒相关的分类学上未指定的病毒组成。这些病毒能够跨越物种边界，共同感染单一宿主菌株并引起宿主表型变化。随着时间的推移，异担子感染中心的病毒丰度不断增加，并且它们成为真菌 RNA 干扰的目标。长期的实地研究对于全面了解病毒在自然界中的影响至关重要。 (C) 2015 Elsevier B.V. 保留所有权利。
The genus Heterobasidion consists of several species of necrotrophic and saprotrophic fungi, and includes some of the most detrimental organisms in boreal conifer forests. These fungi host a widespread and diverse mycovirus community composed of more than 16 species of Partitiviridae, a species of Narnaviridae and one taxonomically unassigned virus related to the Curvularia thermal tolerance virus. These viruses are able to cross species borders, co-infect single host strains and cause phenotypic changes in their hosts. The abundance of viruses increases over time in Heterobasidion infection centers, and they are targeted by fungal RNA interference. Long-term field studies are essential for obtaining a comprehensive view of virus effects in the nature. (C) 2015 Elsevier B.V. All rights reserved.
