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 families Alphaflexiviridae and Betaflexiviridae (subfamily Quinvirinae). 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 family Betaflexiviridae and subfamily Quinvirinae 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 family Betaflexiviridae.
