Geminiviridae
Sign in to saveGeminiviridae is a family of plant viruses that encode their genetic information on a circular genome of single-stranded (ss) DNA. The family contains 18 genera. Diseases associated with this family include: bright yellow mosaic, yellow mosaic, yellow mottle, leaf curling, stunting, streaks, reduced yields. They have single-stranded circular DNA genomes encoding genes that diverge in both directions from a virion strand origin of replication (i.e. geminivirus genomes are ambisense). According to the Baltimore classification they are considered class II viruses. It is the largest known family o

According to the Baltimore classification they are considered class II viruses. It is the largest known family of single stranded DNA viruses.
Mastrevirus and curtovirus transmission is via various leafhopper species (e.g. maize streak virus and other African streak viruses are transmitted by Cicadulina mbila), the only known topocuvirus species, Tomato pseudo-curly top virus, is transmitted by the treehopper Micrutalis malleifera, and begomoviruses are transmitted by the whitefly species, Bemisia tabaci.
