Comoviridae Categories.

	Comovirus - A genus of plant viruses of the family COMOVIRIDAE in which the bipartite genome is encapsidated in separate icosahedral particles. Mosaic and mottle symptoms are characteristic, and transmission is exclusively by leaf-feeding beetles. Cowpea mosaic virus is the type species.
	Fabavirus - A genus of the family COMOVIRIDAE with a wide host range among dicotyledons and some monocotyledons. They are transmitted nonpersistently by aphids. The type species is broad bean wilt virus 1.
	Nepovirus - A genus of polyhedral plant viruses of the family COMOVIRIDAE causing ringspots and spotting on leaves or sometimes symptomless infection. Transmission occurs by seeds, soil nematodes, or experimentally by mechanical inoculation. Tobacco ringspot virus is the type species.
