Complete genome sequence of cnidium virus 2, a novel cytorhabdovirus isolated from Cnidium officinale in South Korea.

High-throughput sequencing identified a cytorhabdovirus, tentatively named "cnidium virus 2" (CnV2), in Cnidium officinale, and Sanger sequencing confirmed the genome sequence. CnV2 is 13,527 nucleotides in length and contains seven open reading frames in the order 3'-N-P-3-4-M-G-L-5', separated by intergenic regions. The full-length nucleotide sequence of CnV2 shares 19.4-53.8% identity with other known cytorhabdovirus genome sequences. The N, P, P3, M, G, and L proteins share 15.8-66.7%, 11-64.3%, 11.1-80.5%, 10.8-75.3%, 12.3-72.1%, and 20-72.7% amino acid sequence identity, respectively, with the cognate deduced protein sequences from known cytorhabdoviruses. CnV2 is related to other members of the genus Cytorhabdovirus, with sambucus virus 1 being the closest relative. Thus, CnV2 should be classified as a new member in the genus Cytorhabdovirus of the family Rhabdoviridae.
