A new virus belonging to the genus Vitivirus in the family Betaflexiviridae was identified by next-generation sequencing of a blueberry plant showing green mosaic symptoms. The genome organization of the virus, which is tentatively named "blueberry green mosaic-associated virus" (BGMaV), is typical of vitiviruses, with five open reading frames (ORFs) and a polyadenylated 3' terminus. The ORFs code for the viral replicase, a 16K protein of unknown function, a movement protein, a coat protein (CP), and a nucleic acid binding protein. Phylogenetic analyses based on the deduced amino acid sequence of the CP and conserved motifs of the RNA-dependent RNA polymerase confirmed the taxonomic placement of BGMaV in the genus Vitivirus.
通过对表现出绿斑症状的蓝莓植株进行下一代测序，发现了一种属于贝塔柔病毒科葡萄病毒属的新病毒。该病毒的基因组组织，暂命名为“蓝莓绿斑伴随病毒”（BGMaV），是典型的葡萄病毒，具有五个开放阅读框（ORFs）和一个聚腺苷酸化的 3'末端。ORFs 编码病毒复制酶、一个功能未知的 16K 蛋白、运动蛋白、外壳蛋白（CP）和核酸结合蛋白。基于 CP 的推导氨基酸序列和 RNA 依赖的 RNA 聚合酶的保守基序的系统发育分析证实了 BGMaV 在葡萄病毒属中的分类地位。
