They suggested that spherical viruses such as Tomato bushy stunt virus had icosahedral symmetry and were made from 60 identical subunits.
4.
"' Rice tungro spherical virus ( RTSV ) "'is a plant pathogenic virus of the family Sequiviridae.

The generalized Thomson problem arises, for example, in determining the arrangements of the protein subunits which comprise the shells of spherical viruses.
6.
The best example is represented by the case of CHV1 and " C . parasitica " . and the mushroom diseases caused by Oyster mushroom spherical virus and Oyster mushroom isometric virus.
7.
The spherical virus particles ( virions ) of Togaviridae have a diameter of 50 to 70 nm and are covered by a lipid membrane ( viral envelope ), derived from the host cell membrane.
