Genome structure and diversity of a novel ophio-like virus that infects the phytopathogenic fungus Rhizoctonia solani.
A new negative-stranded ophio-like RNA mycovirus, Rhizoctonia solani mycoophiovirus 1 (RsMOPV1), was isolated from strain JZ56 of Rhizoctonia solani AG-1 IA. The full-length RNA genome of RsMOPV1 is 7,317 nucleotides (nt) in length and consists of a single long open reading frame (ORF). The ORF encodes an RNA-dependent RNA polymerase (RdRp) consisting of 7,138 amino acids, with a predicted molecular mass of 273 kDa. The coding region of the RsMOPV1 genome is flanked by a short structured 3' untranslated region (3'-UTR) of 58 nucleotides and a 5' untranslated region (5'-UTR) of 121 nucleotides. We did not detect any additional segments of RsMOPV1. The nucleotide sequence of the genome of RsMOPV1 shares 74.7% identity with that of Rhizoctonia solani negative-stranded virus 2. RsMOPV1 infections may be associated with hypovirulence and a slow growth rate in R. solani. The RdRp of RsMOPV1 contains five typical RdRp motifs. Phylogenetic analysis demonstrated that RsMOPV1 clusters with members of the previously proposed genus "Mycoophiovirus".
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.
