Family: Inoviridae

Genus: Parhipatevirus


Distinguishing features

The only species in the genus, Ralstonia virus PE226, is known from phage isolated from plant rhizosphere using Ralstonia solanacearum as a host. Ralstonia phage PE226 has a genome of 5,475 bases (61.7% G+C) that encodes 9 proteins and is able to form clear plaques. Virions have an average length of 1,050 ± 200 nm and a width of 6–9 nm (Murugaiyan et al., 2011)
