Complete genome sequence of cnidium virus 1, a novel betanucleorhabdovirus infecting Cnidium officinale

초록

The complete genomic sequence of a plant rhabdovirus that was identified in Cnidium officinale in Yeongyang-dun, South Korea, is reported here. The virus, tentatively named "cnidium virus 1" (CnV1), has a negative-sense RNA genome of similar to 14 kb, and its organization most closely resembles that of unsegmented plant rhabdoviruses, containing six antisense open reading frames (ORFs) in the order 3'-N-P-P3-M-G-L-5'. Intergenic regions containing conserved sequences separate the genes. The genome of CnV1 is 37.8-56% identical in its complete nucleotide sequence to betanucleorhabdoviruses and other related rhabdoviruses. Therefore, based on the sequence similarity criteria for species demarcation, its genome organization, and its phylogenetic position, CnV1 should be classified as a new member of the genus Betanucleorhabdovirus in the family Rhabdoviridae. CnV1 is the first rhabdovirus found in C. officinale.
