Abstract
We report two novel RNA viruses from yellow crazy ants, (Anoplolepis gracilipes) detected using next-generation sequencing. The complete genome sequences of the two viruses were 10,662 and 8,238 nucleotides in length, respectively, with both possessing two open reading frames with three conserved protein domains. The genome organization is characteristic of members of the genus Triatovirus in the family Dicistroviridae. The two novel viruses were tentatively named “Anoplolepis gracilipes virus 1” and “Anoplolepis gracilipes virus 2” (AgrV-1 and AgrV-2). Phylogenetic analyses based on amino acid sequences of the non-structural polyprotein (ORF1) suggest that the two viruses are triatovirus-like viruses. This is the first report on the discovery of novel triatovirus-like viruses in yellow crazy ants with a description of their genome structure (two ORFs and conserved domains of RNA helicase, RNA-dependent RNA polymerase, and capsid protein), complete sequences, and viral prevalence across the Asia-Pacific region.
