The genome of a novel rhabdovirus was detected in yerba mate (Ilex paraguariensis St. Hil.). The newly identified virus, tentatively named "yerba mate virus A" (YmVA), has a genome of 14,961 nucleotides. Notably, eight open reading frames were identified in the antigenomic orientation of the negative-sense, single-stranded viral RNA, including two novel accessory genes, in the order 3'-N-P-3-4-M-G-L-8-5'. Sequence comparisons of the encoded proteins as well as phylogenetic analysis suggest that YmVA is a new member of the genus Cytorhabdovirus, family Rhabdoviridae. YmVA's unique genomic organization and phylogenetic relationships indicate that this virus likely represents a distinct evolutionary lineage among the cytorhabdoviruses.
在巴拉圭冬青（Ilex paraguariensis St. Hil.）中检测到一种新型弹状病毒的基因组。新鉴定的病毒暂时命名为“冬青病毒 A”（YmVA），其基因组为 14961 个核苷酸。值得注意的是，在负义单链病毒 RNA 的抗原基因组方向上鉴定出了 8 个开放阅读框，包括两个新的辅助基因，其顺序为 3'-N-P-3-4-M-G-L-8-5'。编码蛋白的序列比较以及系统发育分析表明，YmVA 是 Cytorhabdovirus 属、Rhabdoviridae 科的一个新成员。YmVA 独特的基因组组织和系统发育关系表明，该病毒可能代表 Cytorhabdoviruses 中的一个独特进化谱系。
