Complete sequence and genome characterization of miscanthus virus M, a new betaflexivirus from Miscanthus sp.

AbstractA novel betaflexivirus, tentatively named “miscanthus virus M” (MiVM), was isolated fromMiscanthus sp. The complete genome of MiVM is 7,388 nt in length (excluding the poly(A) tail). It contains five open reading frames and has a genome organization similar to those of members of the familiesAlphaflexiviridae andBetaflexiviridae (subfamilyQuinvirinae). The amino acid sequences of both the replicase and coat protein shared less than 45% identity with the corresponding sequences of members of either family. Phylogenetic analysis confirmed that MiVM belongs to the familyBetaflexiviridae and subfamilyQuinvirinae but it was too distantly related to be included in any currently recognized genus in this family. We therefore propose that miscanthus virus M represents a new species and a new genus in the familyBetaflexiviridae.
