In this study, a novel mycovirus designed Colletotrichum gloeosporioides ourmia-like virus 1 (CgOLV1) was isolated from a filamentous phytopathogenic fungus, Colletotrichum gloeosporioides. The virus has a genome of 2,516 nucleotides and contains a large open reading frame (ORF) encoding an RNA-dependent RNA polymerase (RdRp). Phylogenetic analysis indicated that CgOLV1 is located in the ourmia-like mycovirus clade, whose members are related to plant ourmiaviruses. To the best of our knowledge, this is the first report of an ourmia-like mycovirus in C. gloeosporioides.
在这项研究中，一种新型的真菌病毒——拟盘多毛孢 Ourmia-like 病毒 1（CgOLV1）被从丝状植物病原菌——炭疽菌中分离出来。该病毒基因组全长 2516 个核苷酸，包含一个编码 RNA 依赖性 RNA 聚合酶（RdRp）的大开放阅读框（ORF）。系统发育分析表明，CgOLV1 位于拟盘多毛孢病毒科，其成员与植物 Ourmiaviruses 相关。据我们所知，这是首次在炭疽菌中发现拟盘多毛孢病毒。
