The complete nucleotide sequence of a new member of the unassigned genus Sobemovirus, isolated from raspberry and bramble plants in north east Scotland and given the name Rubus chlorotic mottle virus (RuCMV), was obtained. The virus has a single, positive-strand RNA genome of 3983 nucleotides and, in common with other sobemoviruses, contains four open reading frames (ORFs) encoding, from 5’ to 3’, the P1 protein that is likely to be a suppressor of RNA silencing, ORF2a that has homology to serine-proteases, ORF2b that is the probable RNA dependent RNA polymerase, and ORF3 that is the coat protein. ORF2b protein is potentially expressed as a fusion with ORF2a protein by a -1 frameshift at the heptanucleotide sequence UUUAAAC. Phylogenetic analyses showed that RuCMV is a distinct virus not closely related to any of the other sequenced sobemoviruses. Based on the obtained sequence a full-length cDNA copy of RuCMV was cloned and in vitro transcripts derived from this clone were shown to be fully infectious.
