Abstract:
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.
