Complete genome sequence of mimosa mosaic virus, a new sobemovirus infecting Mimosa sensitiva L.

A new sobemovirus, which we have named mimosa mosaic virus (MimMV), was found by high-throughput sequencing and isolated from a mimosa (Mimosa sensitiva L.) plant. The genome sequence was confirmed by Sanger sequencing and comprises 4595 nucleotides. Phylogenetic analysis based on the predicted amino acid (aa) sequences of the P2b protein (encoded by ORF2b) and the coat protein showed 52.7% and 31.8% aa sequence identity, respectively, to those of blueberry shoestring virus. The complete genome sequence of MimMV was less than 47% identical to those of other sobemoviruses. These data suggest that MimMV is a member of a new species in the genus Sobemovirus, for which the binomial name Sobemovirus mimosae is proposed.

Automated summary

A new sobemovirus, named mimosa mosaic virus (MimMV), was discovered and isolated from a mimosa plant using high-throughput sequencing. The genome sequence, confirmed by Sanger sequencing, consists of 4595 nucleotides. Phylogenetic analysis based on predicted amino acid sequences showed that MimMV shares 52.7% and 31.8% sequence identity with the P2b protein and coat protein of blueberry shoestring virus, respectively. The complete genome sequence of MimMV shares less than 47% identity with other sobemoviruses, suggesting that it belongs to a new species named Sobemovirus mimosae.
