★ ★ ★ ★ ★

The use of plant cell-based systems in the study of the Bromoviridae family of multipartite single-stranded plant RNA viruses facilitated the discovery and dissection of viral processes engaged in the single-cell reproduction cycle: replication, transcription, protein synthesis, movement, virion assembly, and RNA recombination. This review ...

★ ★ ★ ★ ★

Virgaviridae is a family of positive sense, single-stranded RNA viruses.Plants serve as natural hosts. There are currently 59 species in this family, divided among 7 genera. The name of the family is derived from the Latin word virga (rod), as all viruses in this family are rod-shaped.
