摘要

本研究从食用菌Pleurotus pulmonarius中鉴定出一种新的有丝分裂病毒，命名为“Pleurotus pulmonarius duamitovirus 1”（PpDMV1）。基因组测序显示，一个2,622核苷酸（nt）的基因组包含一个2,001 nt的开放阅读框（ORF），编码RNA依赖性RNA聚合酶（RdRp）。使用BLASTx进行全基因组序列比较，结果显示该病毒与Erysiphe necator相关的有丝分裂病毒15 （EnMV15）序列相似性最高（56.68%）。系统发育分析将PpDMV1定位为duamitvirus属（有丝分裂病毒科）。据我们所知，这是首例肺假单胞菌有丝分裂病毒感染的报告。

Molecular characterization of a novel mitovirus from the edible fungus Pleurotus pulmonarius

In this study, we identified a novel mitovirus, designated as "Pleurotus pulmonarius duamitovirus 1" (PpDMV1), from the edible fungus Pleurotus pulmonarius. Genome sequencing revealed a 2,622-nucleotide (nt) genome containing a single 2,001-nt open reading frame (ORF) encoding an RNA-dependent RNA polymerase (RdRp). Full-length genome sequence comparisons using BLASTx demonstrated the closest sequence similarity (56.68% identity) to Erysiphe necator associated mitovirus 15 (EnMV15). Phylogenetic analysis positioned PpDMV1 within the genus Duamitovirus (family Mitoviridae). To our knowledge, this is the first report of a mitovirus infection in P. pulmonarius.

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.
