A novel iflavirus was discovered in Psammotettix alienus by RNA sequencing. The virus genome has 10,826 nucleotides (nt) excluding the poly A tail, encodes a 3187-amino-acid polyprotein, and is tentatively named "Psammotettix alienus iflavirus 1" (PaIV1). PaIV1 has a similar genomic structure, conserved motifs, and a close phylogenetic relationship to members of the genus Iflavirus, but it shows only 41.9-55.2% sequence identity in the full genome and 16.2-49% in the deduced polyprotein. Thus, we suggest that it is a new member of the genus Iflavirus, family Iflaviridae.
通过RNA测序在异沙叶蝉中发现了一种新型艾弗病毒。该病毒基因组不包括多聚A尾时含有10826个核苷酸（nt），编码一个3187个氨基酸的多聚蛋白，并被暂命名为“异沙叶蝉艾弗病毒1”（PaIV1）。PaIV1具有与艾弗病毒属成员相似的基因组结构、保守基序以及密切的系统发育关系，但它在全基因组中的序列同一性仅为41.9 - 55.2%，在推导的多聚蛋白中的序列同一性为16.2 - 49%。因此，我们认为它是艾弗病毒科艾弗病毒属的一个新成员。
