Genus: Cryspovirus
Family: Partitiviridae
Genus: Cryspovirus
All members of the genus Deltapartitivirus infect plants. Deltapartitiviruses have two dsRNA segments that are believed to be individually encapsidated in separate particles and the genome is typically 3.1–3.2 kbp in total.
All known members of the genus Gammapartitivirus infect ascomycetous fungi. Gammapartitiviruses have two dsRNA segments that are believed to be individually encapsidated in separate particles. The genome is typically 3.1–3.4 kbp in total.
Members of the genus Betapartitivirus infect plants and fungi. Betapartitiviruses have two dsRNA segments that are believed to be individually encapsidated in separate particles, and genomes typically ranging from 4.3–4.8 kbp in total.
Members of the genus Alphapartitivirus infect plants, ascomycetous or basidiomycetous fungi. All members have two dsRNA segments of similar sizes that are individually encapsidated in separate particles. Alphapatitivirus genomes typically range from 3.6 to 3.9 kbp in total.
