Here, we report the molecular characterization of a novel partitivirus from Phomopsis vexans strain PvHZ002, a plant-pathogenic fungus infecting eggplant. The virus was designated "Phomopsis vexans partitivirus 1" (PvPV1). PvPV1 contains two dsRNA segments, dsRNA1 and dsRNA2, which are 1,662 bp and 1,628 bp long, respectively. Each segment contains a single open reading frame, putatively encoding RNA-dependent RNA polymerase (dsRNA 1) and capsid protein (dsRNA 2). A homology search and phylogenetic analysis showed that PvPV1 clustered with viruses of the genus Deltapartitivirus of the family Partitiviridae.
在此，我们报道了从茄褐纹拟茎点霉PvHZ002菌株（一种感染茄子的植物病原真菌）中分离出的一种新型分病毒的分子特征。该病毒被命名为“茄褐纹拟茎点霉分病毒1”（PvPV1）。PvPV1包含两个双链RNA片段，即dsRNA1和dsRNA2，长度分别为1662 bp和1628 bp。每个片段都包含一个单一的开放阅读框，推测分别编码依赖RNA的RNA聚合酶（dsRNA 1）和衣壳蛋白（dsRNA 2）。同源性搜索和系统发育分析表明，PvPV1与分病毒科Delta分病毒属的病毒聚集在一起。
