A novel iflavirus, tentatively named "Sogatella furcifera honeydew virus 1" (SFHV1), discovered through transcriptome sequencing analysis of white-backed planthoppers (Sogatella furcifera) collected in southern China, is described here. The full genome of SFHV1 is 10,837 nucleotides (nt) long, including the polyA tail, and shares 65.5% and 64.5% genomic identity with Laodelphax striatellus picorna-like virus 2 and Laodelphax striatella honeydew virus 1, respectively. On the basis of the phylogenetic analysis of the complete genomic sequence and the deduced RdRp amino acid sequence of SFHV1 with other iflaviruses, we suggest that it is a member of a new species in the genus Iflavirus, family Iflaviridae.
本文描述了一种新的艾弗病毒，暂命名为“白背飞虱蜜露病毒1”（SFHV1），它是通过对采自中国南方的白背飞虱（Sogatella furcifera）进行转录组测序分析发现的。SFHV1的全基因组长度为10,837个核苷酸（nt），包括polyA尾，与灰飞虱类微小核糖核酸病毒2和灰飞虱蜜露病毒1的基因组同一性分别为65.5%和64.5%。基于SFHV1完整基因组序列和推导的RdRp氨基酸序列与其他艾弗病毒的系统发育分析，我们认为它是艾弗病毒科艾弗病毒属一个新物种的成员。
