ICTV Virus Taxonomy Profile: Quadriviridae.

The Quadriviridae is a monogeneric family of non-enveloped spherical viruses with quadripartite dsRNA genomes, each segment of 3.5-5.0 kbp, comprising 16.8-17.1 kbp in total. The family includes the single species Rosellinia necatrix quadrivirus 1. All quadriviruses infect filamentous fungi, and have unique virion structures compared with other known dsRNA viruses. Pathogenicity has not been reported for these viruses. This is a summary of the ICTV Report on the taxonomy of family Quadriviridae, which is available at http://www.ictv.global/report/quadriviridae.
