The bisegmented genome of a novel double-stranded (ds) RNA mycovirus, named "Aspergillus nidulans partitivirus 1" (AnPV1), isolated from the fungus Aspergillus nidulans strain HJ5-47, was sequenced and analyzed. AnPV1 contains two segments, AnPV1-1 and AnPV1-2. AnPV1-1 has 1837 bp with an open reading frame (ORF) that potentially encodes a putative RNA-dependent RNA polymerase (RdRp) of 572 amino acids (aa). AnPV1-2 has 1583 bp with an ORF encoding a putative capsid protein (CP) of 488 aa. Phylogenetic analyses indicated that AnPV1 and related viruses clustered in a group that could represent a new unclassified genus in the family Partitiviridae.
一株新型双链（ds）RNA 真菌病毒，命名为“aspergillus nidulans partitivirus 1”（AnPV1），从真菌aspergillus nidulans 菌株 HJ5-47 中分离出来，其双节段基因组已被测序和分析。AnPV1 包含两个片段，AnPV1-1 和 AnPV1-2。AnPV1-1 长 1837bp，含有一个潜在编码 572 个氨基酸（aa）的 RNA 依赖的 RNA 聚合酶（RdRp）的开放阅读框（ORF）。AnPV1-2 长 1583bp，含有一个编码 488 个氨基酸的衣壳蛋白（CP）的 ORF。系统发育分析表明，AnPV1 及其相关病毒聚集在一个群体中，该群体可能代表了二分病毒科中的一个新未分类属。
