ICTV Virus Taxonomy Profile: Potyviridae

TLDR

Potyviridae is the largest family of RNA plant viruses, comprising single‑stranded, positive‑sense RNA genomes and flexuous filamentous particles 680–900 nm long, with eight genera distinguished by host range, genomic features, and phylogeny, and genomes ranging 8.2–11.3 kb, mostly monopartite except for bipartite Bymovirus members, many of which cause serious disease epidemics in cultivated plants. The authors aim to summarize the International Committee on Taxonomy of Viruses (ICTV) report on Potyviridae taxonomy. The ICTV Potyviridae taxonomy report is summarized and available at www.ictv.global/report/potyviridae.

Abstract

The Potyviridae is the largest family of RNA plant viruses, members of which have single-stranded, positive-sense RNA genomes and flexuous filamentous particles 680-900 nm long and 11-20 nm wide. There are eight genera, distinguished by the host range, genomic features and phylogeny of the member viruses. Genomes range from 8.2 to 11.3 kb, with an average size of 9.7 kb. Most genomes are monopartite but those of members of the genus Bymovirus are bipartite. Some members cause serious disease epidemics in cultivated plants. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Potyviridae, which is available at www.ictv.global/report/potyviridae.
