Detection of geminiviruses from tropical countries
By using DAS-ELISA and two monoclonal antibodies prepared against particles of a Nigerian isolate of African cassava mosaic geminivirus, it was possible to differentiate African geminiviruses (tomato yellow leaf curl from Senegal (EPPO A2 quarantine pest); African cassava mosaic virus from West and East Africa, okra leaf curl from Côte d'Ivoire), from those originating in other parts of the world (Euphorbia mosaic virus from America, Indian cassava mosaic virus and tomato yellow leaf curl both from India). The authors concluded that these two monoclonal antibodies can allow the detection of whitefly-transmitted geminiviruses from various plants and various geographical origins and could be used on a large scale for epidemiological, sanitation or resistance programmes. However, when the full identification of the virus is needed other tests should be performed (symptomatology, transmission and host range).
