Discovery of three RNA viruses using ant transcriptomic datasets.

Abstract

Three novel RNA viruses, named Formica fusca virus 1 (GenBank accession no. MH477287), Lasius neglectus virus 2 (MH477288) and Myrmica scabrinodis virus 2 (MH477289), were discovered in ants collected in Cambridge, UK. The proposed virus names were given based on the hosts in which they were identified. The genome sequences were obtained using de novo transcriptome assembly of high-throughput RNA sequencing reads and confirmed by Sanger sequencing. Phylogenetic analysis showed that Formica fusca virus 1 grouped within the family Nyamiviridae, Lasius neglectus virus 2 grouped within the family Rhabdoviridae and Myrmica scabrinodis virus 2 belongs to the family Dicistroviridae. All three viruses are highly divergent from previously sequenced viruses.
