Interpretive Summary: Virus taxonomy must be periodically re-examined in order to ensure that virus classification remains current in light of new knowledge and the discovery of novel virus species. Current knowledge pertaining to the plant virus family Ophioviridae is presented for the International Committee on Taxonomy of Viruses. This information will aid the correct classification of any newly emerging viruses associated with this family, and provide a resource for virologists for comparative purposes.

Technical Abstract: The Ophioviridae is a family of filamentous plant viruses, with a single stranded negative, and possibly ambisense, RNA genome of 11.3–12.5 kb in length divided into 3–4 segments, each separately encapsidated by a single coat protein (43–50 kDa). Virions are naked filamentous nucleocapsids, in shape of kinked circles of at least two different contour lengths. Since only one genus is currently recognized, the family description corresponds to the genus Ophiovirus, and the type species is Citrus psorosis virus (CPsV). The family has seven members, of which four are known to be soil-transmitted. Natural hosts of the ophioviruses include trees, shrubs, vegetables and bulbous or corm-forming ornamentals, both monocots and dicots.
