RNA was extracted from 'Hugh Dickson' rose leaves displaying virus-like symptoms in Maryland, USA. Using high-throughput sequencing, we identified a new virus, tentatively named "rose virus R". This virus has a negative-sense, single-stranded RNA genome and exhibits genomic features of a rhabdovirus, including a genome organization of 3'-N-P-P3-M-G-P6-L-5' and a gene junction region consensus sequence 3'-AUUUAUUUUGACUCUA-5'. Rose virus R is phylogenetically related to cytorhabdoviruses, and the nucleotide and amino acid sequences of rose virus R and related cytorhabdoviruses have diverged considerably, suggesting that rose virus R should be classified as a member of a novel species in the genus Cytorhabdovirus.
