Abstract
In this investigation, we identified a novel mitovirus from the phytopathogenic fungus Colletotrichum camelliae strain HNCS-Cc7 and named it "Colletotrichum camelliae mitovirus 1" (CcMV1). Whole-genome sequencing revealed that CcMV1 has 2,650 nucleotides with an A + U content of 62%. The CcMV1 genome contains a single open reading frame (ORF) that encodes an RNA-dependent RNA polymerase (RdRP) of 756 amino acids with a molecular mass of 84.67 kDa. Using a BLASTp search, the CcMV1-RdRp demonstrated the closest sequence similarity to Sclerotinia nivalis mitovirus 2 (61.55%), Sclerotinia sclerotiorum mitovirus 3 (62.03%), and Botrytis cinerea mitovirus 7 (61.60%). Phylogenetic analysis suggested that CcMV1 is a new member of the genus Duamitovirus of the family Mitoviridae. To our knowledge, this is the first report of a mitovirus infecting C. camelliae.
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.
