Abstract
Ourmiaviruses are ssRNA viruses not assigned to any family, with a tripartite genome and cylindrical particles with conical ends. The three species described so far infect plants inducing mosaic, mottle, necrosis on the leaves: Ourmia melon virus (OuMV, the type species), Epirus cherry virus (EpCV) and Cassava virus C (CsVC). Ourmiaviruses appear derived by reassortment of genetic elements of very distant viruses. The RNA-dependent RNA polymerase (RdRp) shows relationships with viruses of invertebrates and fungi, the movement protein (MP) with tombusviruses, the coat protein (CP) shows distant affinities with the CPs of sobemo-, tombus- luteo- and nodaviruses.
