Complete genomic sequence of tea-oil camellia deltapartitivirus 1, a novel virus from Camellia oleifera

Three viral contig sequences, which represented complete genome of a novel virus with three dsRNAs of 1,712 nucleotides (nt) (dsRNA1), 1,504 nt (dsRNA2) and 1,353 nt (dsRNA3), were found in tea-oil camellia plants by high-throughput sequencing analysis. The three dsRNAs were re-sequenced by RT-PCR cloning. The largest dsRNA, dsRNA1, had a single open reading frame (ORF) that encoded a putative 52.7-kDa protein of a putative viral RNA-dependent RNA polymerase (RdRp). DsRNA2 and dsRNA3 were predicted to encode putative capsid proteins (CPs) of 40.47 kDa and 40.59 kDa, respectively. The virus, which is provisionally named “tea-oil camellia deltapartitivirus 1”, shared amino acid sequence itentities of 36.09-69.18% with members of the genus Deltapartitivirus on RdRp. Phylogenetic analysis based on RdRp also placed the new virus and other deltapartitiviruses together in a group, suggesting that this virus should be considered a new member of the genus Deltapartitivirus.
