Molecular characterization of a novel victorivirus isolated from Stagonosporopsis citrulli
Members of the fungal genus Stagonosporopsis are important plant pathogens that can cause severe disease on a wide range of economically important plants and crops. Here, a novel victorivirus, tentatively named "Stagonosporopsis citrulli victorivirus 1" (SciVV1), was isolated from S. citrulli isolate HS2-8. The SciVV1 genome is 5,163 nucleotides in length, with a predicted GC content of 63.85%, and contains two open reading frames (ORF1 and ORF2), which overlap at an AUGA sequence. ORF1 and ORF2 are predicted to encode a coat protein (CP) and an RNA-dependent RNA polymerase (RdRp). A phylogenetic tree based on RdRp amino acid (aa) sequences showed that SciVV1 clustered together with members of the genus Victorivirus in the family Pseudototiviridae. Our results indicate that SciVV1 is a novel victorivirus. This is the first report of the complete genome sequence of SciVV1 infecting S. citrulli.
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.
