to produce a smooth surface.

Characteristics

Like other members of the ''

'' 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.
