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.
通过高通量测序，从一株具有环斑症状的山茶树（Camellia japonica）中鉴定出一个与亚洲李痘病毒 2 具有高度序列相似性的大片段。该新病毒的完整基因组大小为 8829 个核苷酸，不包括 3' 多聚（A）尾。其基因组结构类似于已知的痘病毒科病毒，但在 3' 末端区域含有一个额外的开放阅读框。系统进化分析也将该病毒与β病毒科β flexiviridae 属的成员归为同一亚群。该病毒暂命名为“山茶叶环斑相关病毒 4”，与其他痘病毒科病毒的核苷酸序列同源性为 50-56%，应代表该属的一个新种。
