In the present study, the genome sequence of a potential novel virus, tentatively named "rose virus C" (RVC), was mined from publically available transcriptomic data from a Rosa chinensis plant. The complete genome sequence of RVC consists of 8,386 nt, excluding a 3' poly(A) tail, and contains five ORFs. Phylogenetic analysis showed that RVC clustered with members of the genus Carlavirus, family Betaflexiviridae. The replicase gene had 48.8-52.1% nt sequence identity to those of other carlaviruses, while the CP gene had 40.4-45.9% nt sequence identity, which is far below the species demarcation cutoff of 72%. The incidence of RVC in rose plants was low (5.4%). Overall, our data suggest that RVC is a novel atypical virus of the genus Carlavirus.
在本研究中,从 Rosa chinensis 植物的公开转录组数据中挖掘出一种潜在的新型病毒,暂命名为“玫瑰病毒 C”(RVC)。RVC 的完整基因组序列由 8386 个核苷酸组成,不包括 3' poly(A) 尾,包含五个 ORFs。系统发育分析表明,RVC 与卡尔病毒属的成员聚为一簇,属于贝塔病毒科。复制酶基因与其他卡尔病毒的核苷酸序列同一性为 48.8-52.1%,而 CP 基因的核苷酸序列同一性为 40.4-45.9%,远低于 72%的种间区分界限。RVC 在玫瑰植物中的发病率较低(5.4%)。总的来说,我们的数据表明 RVC 是卡尔病毒属的一种新型非典型病毒。
