ICTV Virus Taxonomy Profile: Fimoviridae 2024

Abstract

Members of the family Fimoviridae are plant viruses with a multipartite negative-sense enveloped RNA genome (−ssRNA), composed of 4–10 segments comprising 12.3–18.5 kb in total, within quasi-spherical virions. Fimoviruses are transmitted to plants by eriophyid mites and induce characteristic cytopathologies in their host plants, including double membrane-bound bodies in the cytoplasm of virus-infected cells. Most fimoviruses infect dicotyledonous plants, and many cause serious disease epidemics. This is a summary of the ICTV Report on the family Fimoviridae, which is available at ictv.global/report/fimoviridae.
