General Description

This family currently consists of the single genus Chrysovirus. It contains dsRNA viruses that infect fungi and which have four genome components. Some chrysovirus sequences have now also been isolated from plants; it is not yet clear whether these are genuine plant pathogens, or whether they have been isolated from a parasitic fungus within the plant.

Morphology

Virions isometric (icosahedral), not enveloped, 35-40 nm in diameter.

Genomen

Linear, double stranded RNA with four segments, ranging from about 2.9-3.6 kb in size.
