Sedoreovirinae

Sedoreovirinae ("sedo" = smooth) is a subfamily of the "Reoviridae" family of viruses. Viruses in this subfamily are distinguished by the absence of a turreted protein on the inner capsid to produce a smooth surface.
Characteristics.
Like other members of the "Reoviridae" family, viruses of the "Sedoreovirinae" subfamily are made of naked, icosahedral capsids containing 10-12 segments of linear double-stranded RNA (dsRNA). The Baltimore System of viral classification categorizes "Reoviridae" in Group III.
Importance.
Viruses classified in the "Sedoreovirinae" subfamily infect a wide range of plants and animals, including some that can infect humans. There is not only the potential of a few of these viruses to cause human disease, but also to reduce the supply of crops and livestock.
Viruses.
Genus "Cardoreovirus".
"Eriocheir sinensis reovirus" was isolated out of a Chinese mitten crab ("Eriocheir sinensis"). No currently known associated disease.
Genus "Mimoreovirus".
"Microsomonas pusilla reovirus" was isolated from the marine protist "Micromonas pusilla"
Genus "Orbivirus".
Arboviruses containing dsRNA are placed in this genus. Some "Orbivirus" infect livestock with high rates of morbidity and mortality. 
Includes: "Bluetongue virus, African horse sickness virus, Epizootic hemorrhagic disease virus", among others.
Genus "Phytoreovirus".
Known phytoreoviruses are plant pathogens causing dwarfism and the formation of tumors. 
Included: "Rice dwarf virus", "Rice gall dwarf virus", and "Wound tumor virus".
Genus "Rotavirus".
"Rotavirus A-E" cause infantile gastroenteritis in humans and farm animals.
Genus "Seadornavirus".
Many known "Seadornaviruses" cause encephalitis in humans.
Included: "Banna virus", "Kadipiro virus", and "Liao ning virus".
