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.
在本研究中，我们从食用菌肺形侧耳中鉴定出一种新型的线粒体病毒，命名为“肺形侧耳双粒病毒1”（PpDMV1）。基因组测序显示，该病毒基因组为2622个核苷酸（nt），包含一个单一的2001个nt的开放阅读框（ORF），编码一种RNA依赖的RNA聚合酶（RdRp）。使用BLASTx进行的全长基因组序列比较显示，其与葡萄白粉菌相关线粒体病毒15（EnMV15）的序列相似性最高（同一性为56.68%）。系统发育分析将PpDMV1定位在双粒病毒属（线粒体病毒科）内。据我们所知，这是关于肺形侧耳中线粒体病毒感染的首次报道。
