Interpretive Summary: Biological and molecular properties of virus species within the genus Tritimovirus are briefly described. Recent taxonomic revisions of the genus are discussed. As currently defined, the genus Tritimovirus consists of three virus species: Wheat streak mosaic virus, Brome streak mosaic virus, and Oat necrotic mottle virus that were previously assigned to the genus Rymovirus.

Technical Abstract: A brief technical description of plant-infecting RNA viruses of the genus Tritimovirus, family Potyviridae is presented. Described are biological properties, genome organization, and phylogenetic relationships among definitive and tentative virus species of the genus. The genus Tritimovirus consists of three virus species infecting grasses and are transmitted by eriophyid mites. Wheat streak mosaic virus (WSMV) is the type species and Brome streak mosaic virus (BStMV) is a definitive member of the genus. A third virus species, Oat necrotic mottle virus (ONMV) is proposed as a third definitive member. All three viruses were formerly classified in the genus Rymovirus.
