A distinct double-stranded RNA (dsRNA) cryptic virus, named spinach cryptic virus 1 (SpCV1), was identified from spinach transcriptome datasets. The SpCV1 genome has two dsRNA genome segments. The larger dsRNA1 has an open reading frame for a conserved RNA-dependent RNA polymerase (RdRp). The smaller dsRNA2 encodes a putative coat protein (CP). The sequence identity of SpCV1 RdRp and CP to the closest cryptic virus is 81% and 60%, respectively. Phylogenetic analysis indicates that SpCV1 is a novel member of the genus (family ).
从菠菜转录组数据集中鉴定出一种独特的双链RNA（dsRNA）隐性病毒，命名为菠菜隐性病毒1（SpCV1）。SpCV1基因组有两个dsRNA基因组片段。较大的dsRNA1有一个用于保守的RNA依赖性RNA聚合酶（RdRp）的开放阅读框。较小的dsRNA2编码一种假定的衣壳蛋白（CP）。SpCV1的RdRp和CP与最接近的隐性病毒的序列同一性分别为81%和60%。系统发育分析表明，SpCV1是该属（科）的一个新成员。
