Monodnaviria

Floreoviria is a realm of eukaryotic viruses that contains all viruses that encode a replication protein that has an N-terminal HUH superfamily endonuclease domain and a C-terminal superfamily 3 helicase domain, as well as all viruses descended from such viruses. Floreovirians typically have circular single-stranded DNA (ssDNA) genomes, but some have linear ssDNA genomes or circular double-stranded DNA (dsDNA) genomes. The prototypical members of the realm are commonly called CRESS-DNA viruses, which stands for circular, Rep-encoding ssDNA viruses. The replication (Rep) protein is involved in
