Closteroviridae. In: King, A.M.Q., Adams, M.J., Carstens, E.B. and Lefkowitz, E.J. editiors. Virus Taxonomy: Classification and Nomenclature of Viruses. Ninth Report of the International Committee on Taxonomy of Viruses. San Diego. Elsevier Academic Press. p.987-1011.

Interpretive Summary: The Closteroviridae chapter covers updates in taxonomy within this family, highlights the characteristics that delineate genera in the family and lists species that have not been assigned to a genus. There are three recognized genera in the family; the Closteroviruses that are monopartite and transmitted by aphids, the Ampeloviruses that are monopartite and transmitted by mealybugs and/or soft scale insects and the Criniviruses that are whitefly transmitted with one species (Potato yellow vein virus) that is tripartite. The Closteroviruses are unique among plant viruses in that they have incorporated a Heat Shock Protein that is highly conserved among members of the family. The current ICTV (Ninth) report lists 2284 virus and viroid species distributed amongst 349 genera, 19 subfamilies, 87 families and 6 orders. There is also a chapter of unassigned viruses that provides information on a number of viruses that have not yet been classified but which are probably representatives of new genera and/or families. ICTV expects to make regular updates to keep the online version in step with the latest taxonomic decisions.

Technical Abstract: The current ICTV report lists 2284 virus and viroid species distributed amongst 349 genera, 19 subfamilies, 87 families and 6 orders. There is also a chapter of unassigned viruses that provides information on a number of viruses that have not yet been classified but are probably representatives of new genera and/or families. The final chapters describe the satellites (and other virus-dependent nucleic acids) and prions (which include the agents of spongiform encephalopathies of humans), which are not formally classified by ICTV but simply listed for historical reasons. The Ninth Report is being published both as a book and also online. ICTV expects to make regular updates to keep the online version in step with the latest taxonomic decisions. The Closteroviridae chapter covers updates in taxonomy within this family, highlights the characteristics that delineate genera in the family and lists species that have not been assigned to a genus. There are three recognized genera in the family; the closteroviruses that are monopartite and transmitted by aphids, the ampeloviruses that are monopartite and transmitted by mealybugs and the criniviruses that are whitefly transmitted with one species that is tripartite.
