Abstract
A novel cytorhabdovirus was identified in Daphne odora in South Korea using high-throughput sequencing. The virus, tentatively named "daphne virus 1" (DV1), has a full-length genome sequence of 13,206 nucleotides with a genome organization comparable to that of unsegmented plant rhabdoviruses and contains seven antisense putative genes in the order 3'-leader-N-P'-P-P3-M-G-L-5'-trailer. The coding region of the genome is flanked by a 3' leader and a 5' trailer sequence, 261 and 151 nucleotides long, respectively. The DV1 genome shares 33.74%-57.44% nucleotide sequence identity with other cytorhabdoviruses. The DV1-encoded proteins share the highest amino acid sequence identity with homologues from Asclepias syriaca virus 1. Phylogenetic analysis showed that DV1 clustered with representative cytorhabdoviruses. We propose classifying DV1 in a new species within the genus Cytorhabdovirus, family Rhabdoviridae.
