Walter, Laboratoire de Virologie, Centre de Recherches d’Adiopodoumé, Office de la Recherche Scientifique et Technique Outre-Mer, Abidjan, Côte d’Ivoire, Africa. Plant Dis. 64:1040-1042.

A virus was mechanically transmitted from cassava leaves with typical symptoms of the African cassava mosaic disease to Nicotiana benthamiana and to hybrid N. clevelandii × N. glutinosa, and from N. benthamiana to other solanaceous species. The virus was purified and appeared as geminated particles in electron micrographs. This is the first report of a geminivirus in mosaic-diseased cassava in West Africa.
