Aplosporella javeedii is a pathogenic fungus that causes canker and dieback of jujube in China. In this study, we report a new mycovirus, Aplosporella javeedii partitivirus 1 (AjPV1), isolated from A. javeedii strain NX55-3. The AjPV1 genome contains two double-stranded RNA elements (dsRNA1 and dsRNA2). The size of dsRNA1 is 2,360 bp, and it encodes a putative RNA-dependent RNA polymerase (RdRp), while dsRNA2 is 2,301 bp in length and encodes a putative capsid protein (CP). The sequences of RdRp and CP have significant similarity to those of members of the family Partitiviridae. Sequence alignment and phylogenetic analysis showed that AjPV1 is a new member of the family Partitiviridae that is related to members of the genus Betapartitivirus. To our knowledge, AjPV1 is the first mycovirus reported from A. javeedii.
阿朴隔孢腔菌是一种在中国引起枣树溃疡和枯萎病的病原真菌。在本研究中，我们报道了一种新的真菌病毒，阿朴隔孢腔菌二分体病毒 1（AjPV1），它是从阿朴隔孢腔菌菌株 NX55-3 中分离出来的。AjPV1 基因组包含两个双链 RNA 元件（dsRNA1 和 dsRNA2）。dsRNA1 的大小为 2360bp，它编码一个推定的 RNA 依赖性 RNA 聚合酶（RdRp），而 dsRNA2 长 2301bp，编码一个推定的衣壳蛋白（CP）。RdRp 和 CP 的序列与二分体病毒科的成员具有显著的相似性。序列比对和系统发育分析表明，AjPV1 是二分体病毒科的一个新成员，与贝塔二分体病毒属的成员有关。据我们所知，AjPV1 是从阿朴隔孢腔菌中报道的第一种真菌病毒。
