Abstract
Here, we isolated two novel mycoviruses coinfecting the fugus Colletotrichum karstii, which were designated as "Colletotrichum karstii mitovirus 1" (CkMV1) and "Colletotrichum karstii mitovirus 2" (CkMV2). The length of the complete genome of CkMV1 is 2,441 nucleotides, and that of CkMV2 is 2,391 nucleotides. Both contain a single open reading frame (ORF) that encodes an RNA-dependent RNA polymerase (RdRp). BLAST searches showed that the amino acids (aa) sequences of CkMV1 and CkMV2 had the highest amino acid sequence identity of 35.41% and 52.37% to the RdRp of Pleurotus pulmonarius duamitovirus 1 and Fusarium oxysporum f. sp. cubense mitovirus 4, respectively. Phylogenetic analysis based on RdRp sequences revealed that CkMV1 grouped with members of the genus Duamitovirus and that CkMV2 grouped with members of the genus Unuamitovirus, both within the family Mitoviridae.
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.
