ABSTRACT
A novel iflavirus, tentatively named "Langfang leafhopper iflavirus" (LfLHV) was detected in leafhopper (Psammotettix alienus) by total RNA sequencing, and its genome sequence was confirmed by Sanger sequencing. The complete genome consisted of 10,700 nucleotides (nt) excluding the poly A tail and included one open reading frame (9,453 nt in length), encoding a polyprotein of 3,150 amino acids (aa). The nucleotide sequence of the complete genome was shared 44.1-53.3% identical, and the deduced amino acid sequence RNA-dependent RNA polymerase (RdRp) 22-74% identical to those of other iflaviruses. These values were all below the species demarcation threshold of 90%. Conserved motifs for structural proteins, helicase, protease, and RdRp were also similar to those in other iflaviruses. These results, as well as those of phylogenetic analysis based on the deduced amino acid sequences of the polyprotein and RdRp of LfLHV and other iflaviruses, indicate that the sequence represents a novel virus of the family Iflaviridae.
