Abstract

A new polerovirus, named “arachis mottle-associated virus” (ArMoV), was identified by high-throughput sequencing in a Pinto peanut (Arachis pintoi) plant. The genome sequence was confirmed by Sanger sequencing and contains 5775 nucleotides and seven predicted open reading frames (ORFs), showing a typical polerovirus genome structure. All of the proteins encoded by ArMoV showed less than 90% amino acid sequence identity to those of other poleroviruses, the threshold to establish a new species in the genus. Phylogenetic analysis based on P1-P2 fusion protein and coat protein amino acid sequences showed that tobacco polerovirus 1 and chickpea chlorotic stunt virus, respectively, were the most closely related to ArMoV. These data suggest that ArMoV is a member of a new species of the genus Polerovirus, for which the binomial name "Polerovirus ARMOV " is proposed.

花生斑驳相关病毒,一种感染平托花生的新型多角体病毒。
通过高通量测序,在一株品脱花生(Arachis pintoi)中发现了一种新的多瘤病毒,命名为 "花生斑驳相关病毒"(ArMoV)。基因组序列经桑格(Sanger)测序确认,包含 5775 个核苷酸和 7 个预测开放阅读框(ORF),呈现出典型的脊髓灰质炎病毒基因组结构。ArMoV 编码的所有蛋白质与其他多瘤病毒的氨基酸序列同一性均低于 90%,达到了在多瘤病毒属中建立一个新种的临界值。基于 P1-P2 融合蛋白和衣壳蛋白氨基酸序列的系统进化分析表明,烟草多角体病毒 1 和鹰嘴豆枯萎病病毒分别与 ArMoV 的亲缘关系最密切。这些数据表明,ArMoV 是脊髓灰质炎病毒属的一个新种,建议将其命名为 "脊髓灰质炎病毒 ARMOV"。

期刊介绍: Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
