本文对从真菌nidulanaspergillus nidulans HJ5-47株分离的一种新型双链RNA分枝病毒“Aspergillus nidulans partitivirus 1”（AnPV1）进行了双片段基因组测序和分析。AnPV1包含两个网段：AnPV1-1和AnPV1-2。AnPV1-1全长1837 bp，具有开放阅读框（ORF），可能编码572个氨基酸（aa）的RNA依赖性RNA聚合酶（RdRp）。AnPV1-2全长1583 bp， ORF编码推测的衣壳蛋白（CP）长度为488 aa。系统发育分析表明，AnPV1和相关病毒聚集在一个群中，可能代表了分病毒科一个新的未分类属。
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.
