In this work, a novel ssRNA (+) viral genomic sequence with gene organization typical of members of the subfamily Quinvirinae (family Betaflexiviridae) was identified using high- throughput sequencing data of date palm obtained from the Sequence Read Archive database. The viral genome sequence consists of 7860 nucleotides and contains five ORFs encoding for the replication protein (Rep), triple gene block proteins 1, 2, 3 (TGB 1, 2, and 3), and coat protein (CP). Phylogenetic analysis based on the Rep and the CP amino acid sequences showed the closest relationship to garlic yellow mosaic-associated virus (GYMaV). Based on the demarcation criteria of the family Betaflexiviridae, this new virus, provisionally named date palm virus A (DPVA), could constitute a member of a novel genus. However, considering that DPVA and GYMaV share the same genomic organization and that they cluster together on the Rep phylogenetic analysis, they could also constitute a novel genus together, highlighting the necessity of a revision of the taxonomic criteria of the family Betaflexiviridae.

在这项工作中，使用从序列读取档案数据库获得的枣椰树的高通量测序数据，鉴定了一种新的ssRNA（+）病毒基因组序列，该序列具有昆亚科（Betaflexiviridae）家族成员典型的基因组织。病毒基因组序列由7860个核苷酸组成，并包含5个编码复制蛋白（Rep），三重基因阻断蛋白1、2、3（TGB 1、2和3）和外壳蛋白（CP）的ORF。基于Rep和CP氨基酸序列的系统进化分析显示与大蒜黄花叶病相关病毒（GYMaV）的关系最密切。基于贝氏弯曲病毒科的分界标准，这种新病毒，临时命名为枣椰子病毒A（DPVA），可能构成一个新属。但是，考虑到DPVA和GYMaV具有相同的基因组组织，并且它们在Rep系统发育分析中聚集在一起，因此它们也可能共同构成一个新的属，从而强调了修订Betaflexiviridae家族分类标准的必要性。
