摘要

在此，我们报告了一种新型的类疟原虫霉菌病毒，命名为 "拟疟原虫 magoulivirus 1"（PaMV1），它来源于植物病原真菌拟疟原虫（Phomopsis asparagi）。PaMV1 的基因组由正义单链 RNA（+ ssRNA）组成，全长 2 639 个核苷酸，GC 含量为 57.13%。它包含一个开放阅读框（ORF），编码一个假定的 RNA 依赖性 RNA 聚合酶（RdRp），由 686 个氨基酸组成，分子质量为 78.57 kDa。基于 RdRp 序列的系统进化分析表明，PaMV1 与 Diaporthe gulyae magoulivirus 1（DgMV1）组成了一个独特的支系。序列比较和系统进化分析表明，PaMV1 是 Botourmiaviridae Magoulivirus 属的一个新成员。

Complete genome sequence of a novel botourmiavirus infecting the fungus Phomopsis asparagi

Here, we report a novel ourmia-like mycovirus, named “Phomopsis asparagi magoulivirus 1” (PaMV1), derived from the phytopathogenic fungus Phomopsis asparagi. The genome of PaMV1 consists of a positive-sense single-stranded RNA (+ ssRNA) that is 2,639 nucleotides in length, with a GC content of 57.13%. It contains a single open reading frame (ORF) encoding a putative RNA-dependent RNA polymerase (RdRp) consisting of 686 amino acids with a molecular mass of 78.57 kDa. Phylogenetic analysis based on RdRp sequences revealed that PaMV1 grouped together with Diaporthe gulyae magoulivirus 1 (DgMV1) in a distinct clade. Sequence comparisons and phylogenetic analysis suggest that PaMV1 is a novel member of the genus Magoulivirus, family Botourmiaviridae.

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.
