A novel dsRNA virus was identified by high-throughput sequencing from tea oil trees in China. Its complete genome of 4714 bp contains two open reading frames (ORFs). ORF1 encodes a putative coat protein (CP) of 702 amino acids (aa), and ORF2 codes for an RNA-dependent RNA polymerase (RdRp) of 855 aa. The virus shares the highest aa sequence identity of 45.21% in RdRp with taro-associated totivirus L (MN_119621), a member of the genus Totivirus in the family Totiviridae. Phylogenetic analysis of the aa sequences of the RdRp places the new virus in a group with other totiviruses, suggesting that this virus, which is provisionally named "tea-oil camellia-associated totivirus 1", should be considered a member of the genus Totivirus.
一种新型 dsRNA 病毒通过高通量测序在中国的茶油树中被发现。其完整的基因组长 4714bp，包含两个开放阅读框（ORF）。ORF1 编码一个推定的外壳蛋白（CP），由 702 个氨基酸（aa）组成，ORF2 编码一个 RNA 依赖性 RNA 聚合酶（RdRp），由 855 个氨基酸组成。该病毒在 RdRp 区的 aa 序列与芋属 totivirus L（MN_119621）的同源性最高，为 45.21%，芋属 totivirus L 是 Totiviridae 科 Totivirus 属的一个成员。RdRp 区 aa 序列的系统进化分析将新病毒置于与其他 totiviruses 相同的组中，表明该病毒暂命名为“茶油 camellia-associated totivirus 1”，应被视为 Totivirus 属的一员。
