In this study, we describe a novel mycovirus isolated from Trichoderma asperellum, which was designated Trichoderma asperellum dsRNA Virus 1 (TaRV1). The sequence analysis revealed that TaRV1 has two discontinuous open reading frames (ORF), ORF1 and ORF2. A hypothetical protein and an RNA-dependent RNA polymerase are encoded by ORF1 and ORF2, respectively. Phylogenetic analysis based on RdRp sequences clearly places TaRV1 in a taxonomically unassigned dsRNA mycovirus group.
在本研究中，我们描述了一种从棘孢木霉中分离出的新型真菌病毒，将其命名为棘孢木霉双链RNA病毒1（TaRV1）。序列分析表明，TaRV1有两个不连续的开放阅读框（ORF），即ORF1和ORF2。ORF1和ORF2分别编码一种假定蛋白和一种RNA依赖性RNA聚合酶。基于RNA依赖性RNA聚合酶（RdRp）序列的系统发育分析清楚地将TaRV1置于一个分类学上未归属的双链RNA真菌病毒组中。
