Abstract

In this study, we identified a novel mycovirus, Fusarium graminearum ormycovirus 1 (FgOV1), from the pathogenic fungus Fusarium graminearum. The virus has two RNA segments, RNA1 and RNA2, with lengths of 2,591 and 1,801 nucleotides, respectively, excluding the polyA tail. Each segment contains a single open reading frame (ORF). The ORF in RNA1 encodes an RNA-dependent RNA polymerase, while the ORF in RNA2 encodes a hypothetical protein. Phylogenetic analysis showed that FgOV1 belongs to the gammaormycovirus clade, whose members are related to betaormycoviruses. To our knowledge, this is the first report of an ormycovirus in Fusarium graminearum.

从植物致病真菌禾本科镰刀菌中分离出一种新型粘病毒

在这项研究中，我们从致病真菌禾本科镰刀菌中鉴定出了一种新型霉菌病毒--禾本科镰刀菌或霉菌病毒 1（FgOV1）。该病毒有两个 RNA 片段，即 RNA1 和 RNA2，长度分别为 2,591 和 1,801 个核苷酸（不包括 polyA 尾部）。每个片段都包含一个开放阅读框（ORF）。RNA1 中的 ORF 编码一个 RNA 依赖性 RNA 聚合酶，而 RNA2 中的 ORF 编码一个假定蛋白。系统进化分析表明，FgOV1属于γ瘤病毒支系，其成员与β瘤病毒有关。据我们所知，这是首次报道禾本科镰刀菌中的ormycovirus。

期刊介绍： Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
