Objectif The objectives of the project are to control the spread of lethal Yellowing-type diseases in Africa and determine the relationship between diseases in Africa and the Caribbean region. There are two components: 1. Laboratory-based research on development of detection and diagnostic techniques and comparison of mycoplasmalike organisms (MLO) from different regions. Nucleic acid based diagnostic techniques (DNA probes and RAPD analysis) will be developed by the European partners for field use bY African partners. The proposed work Will take advantage of DNA probes and amplification techniques specific for LY MLO that have recently been developed at the University of Florida, USA, who have agreed to collaborate in this work but are not formal partners in this proposal. 2. An African Network of field-based research on the etiology and control of LY. This will concentrate on etiological studies to determine relationships between diseases in different regions and monitor their distribution, and on applied control strategies including resistance screening trials, initiation of breeding-progeny selection, vector identification, training of scientific workers and farmer extension. The two components will interact in the following ways: - The MLO etiology of unknown diseases of coconut in Africa will be confirmed (eg Awka wilt, Nigeria, and lethal disease, Mozambique). - The possibility that different strains of the pathogen exist in East and West Africa and the Caribbean will be tested. Tests will be developed to predict the susceptibility of coconut varieties in different regions. - Tests will help identify MLO in insect vectors and alternative host plants. This will facilitate study of disease epidemioloav and ecoloav. - European labs will provide on-the-job training and technolonv transfer in modern diagnostic techniques. There will be a focus for collaboration between African and Caribbean research groups. Training and support for local extension services will ensure that new'knowledge about the disease and techniques for managing it will become available to farmers. -----se Champ scientifique natural sciencesbiological sciencesbiochemistrybiomoleculesnucleic acidsnatural sciencesbiological sciencesgeneticsDNAnatural sciencesbiological scienceszoologyentomology Programme(s) FP3-STD 3 - Specific research and technological development programme (EEC) in the field of the life sciences and technologies for developing countries, 1990-1994 Thème(s) Data not available Appel à propositions Data not available Régime de financement CSC - Cost-sharing contracts Coordinateur Natural Resources Institute Contribution de l’UE Aucune donnée Adresse Central Avenue Chatham Maritime ME4 4TB Chatham Royaume-Uni Voir sur la carte Liens Site web Opens in new window Coût total Aucune donnée Participants (5) Trier par ordre alphabétique Trier par contribution de l’UE Tout développer Tout réduire Centre de Coopération Internationale en Recherche Agronomique pour le Développement (CIRAD) France Contribution de l’UE Aucune donnée Adresse 34032 Montpellier Voir sur la carte Coût total Aucune donnée Civ.
