To our knowledge, no mycoviruses have been reported in Fusarium cerealis. Here, we describe a novel double-stranded RNA (dsRNA) virus, Fusarium cerealis partitivirus 1 (FcPV1), isolated from F. cerealis strain HN30 from Henan Province, China. The FcPV1 genome consists of two dsRNA segments, 1732 bp (dsRNA1) and 1361 bp (dsRNA2) in length, each containing a single open reading frame potentially encoding a 61.0-kDa protein and a 42.0-kDa protein, respectively. dsRNA1 encodes a putative RNA-dependent RNA polymerase (RdRp), while the dsRNA2 product has no significant similarity to any other capsid proteins (CPs) in the GenBank databases other than limited similarity to hypothetical "capsid" proteins of a few partitiviruses. Sequence alignments and phylogenetic analysis showed that FcPV1 is related to members of the newly proposed genus "Zetapartitivirus" in the family Partitiviridae.
据我们所知，尚未有真菌病毒在禾谷镰刀菌中被报道。在这里，我们描述了一种新型的双链 RNA（dsRNA）病毒，即来自中国河南省的禾谷镰刀菌菌株 HN30 的禾谷镰刀菌二分体病毒 1（FcPV1）。FcPV1 基因组由两条 dsRNA 片段组成，分别长 1732bp（dsRNA1）和 1361bp（dsRNA2），每个片段都包含一个单一的开放阅读框，分别潜在编码一个 61.0-kDa 蛋白和一个 42.0-kDa 蛋白。dsRNA1 编码一个推定的 RNA 依赖性 RNA 聚合酶（RdRp），而 dsRNA2 产物与 GenBank 数据库中除少数二分体病毒的假设“衣壳”蛋白外，与任何其他衣壳蛋白（CP）均无显著相似性。序列比对和系统发育分析表明，FcPV1 与新近提出的二分体病毒科“Zetapartitivirus”属的成员相关。
