Monodnaviria

Monodnaviria is a realm of viruses. The name is derived from the Greek monos meaning "single" and deoxyribonucleic acid (DNA), referring to the type of genetic material found in these viruses. The realm was established by the International Committee on Taxonomy of Viruses (ICTV) in 2019.

Taxonomy

The realm Monodnaviria includes the following kingdoms, phyla, and classes:

• Kingdom: Shotokuvirae
• Phylum: Cossaviricota
• Class: Cossaviricetes
• Phylum: Papillomaviricota
• Class: Papillomaviricetes
• Phylum: Loebviricota
• Class: Loebviricetes
• Phylum: Trapaviricota
• Class: Trapaviricetes

Characteristics

Monodnaviria viruses are characterized by their single-stranded DNA genomes. They infect a wide range of hosts, including animals, plants, and bacteria. The viruses in this realm have diverse morphologies, but all share the common feature of replicating their DNA genomes via a rolling-circle mechanism.

Evolution

The viruses in the realm Monodnaviria are thought to have evolved from a common ancestor that existed more than a billion years ago. This ancient virus is believed to have had a circular, single-stranded DNA genome and to have used a rolling-circle mechanism for replication.
