Abstract
One large contig with high sequence similarity to Asian prunus virus 2 was identified by high-throughput sequencing from a camellia (Camellia japonica) tree with ringspot symptoms. The complete genome of this new virus was determined to be 8829 nucleotides long, excluding the 3′ poly(A) tail. Its genome organization resembles that of known foveaviruses but contains an additional open reading frame in the 3′-terminal region. Phylogenetic analysis also places this virus with members of the genus Foveavirus in the family Betaflexiviridae in the same subgroup. The virus, which is provisionally named "camellia ringspot-associated virus 4″, shares 50–56% nucleotide sequence identity with other foveaviruses and should represent a new species in the genus.
