Interpretive Summary: Roses (Rosa spp.), one of the most popular ornamentals worldwide, are used as both cut flowers and landscape plants. Many viral diseases affect rose production, and it is important to detect and eliminate viruses before roses are propagated and distributed. We report a new virus identified in rose, provisionally named Rose virus R (RVR). The RVR genomic organization and sequence was determined. This study provides information for the proper classification of RVR. The genome sequence facilitates developing reliable detection methods that can be used to screen rose genetic material. This information will help develop better viral control measures in rose trade and production industries.

Technical Abstract: A rose ‘Hugh Dickson’ in Maryland, USA that displayed virus like symptoms was analyzed by high throughput sequencing. We identified a new virus, putatively named rose virus R, in this plant. This negative-sense RNA virus contains 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 placed within cytorhabdoviruses, and the nucleotide identity of cognate open reading frames from rose virus R have diverged from related cytorhabdoviruses, indicating that this is a new species of cytorhabdovirus.
