Description of Nanoviridae

adapted from ICTVdb

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of 17-20.2-26 nm. The capsomer arrangement is not obvious.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.28-1.34 g cm^-3. There are 1 sedimenting component(s) found in purified preparations. A₂₆₀/A₂₈₀ ratio is 1.35-1.375-1.4.

Nucleic Acid

The Mr of the genome constitutes 16-16.5-17% of the virion by weight. The genome is segmented and consists of six segments of to eight segments of circular, single-stranded DNA. The complete genome is 1290-2325-3360 nucleotides long.
