Realm: Monodnaviria

Viruses from this realm are viruses with circular single-stranded DNA genomes and most of them encode a rolling circle replication initiation endonuclease (Rep). The capsids are either helical or icosahedral with T=1 symmetry (single jelly roll (SJR)).

CRESS DNA viruses have evolved on three independent occasions from bacterial rolling-circle replicating plasmids . Due to the simplicity and universal replication mechanism, these viruses are very versatile and can jump to new hosts and evolve rapidly.
