Genus: Nyfulvavirus

Genus: Nyfulvavirus

Distinguishing features

The sole member of the only species in this genus infects ants and has a genome organisation characterised by a single major ORF. This contrasts with the genome organisation of Solenopsis invicta virus 3 (genus Invictavirus), which has two major ORFs with ribosomal frameshifting used to express the 3′ ORF.
