Kitrinoviricota

Single-stranded RNA viruses of the Kitrinoviricota phylum are characterized by a homologous RNA-dependent RNA polymerase (Pfam RdRP_2 or RdRP_3 families). Their capsid are either icosahedral (T=1, 3 or 4) or helical.

Most viruses are classified under Baltimore as ssRNA (+) and some as dsRNA viruses.
