Autre titre : Caractérisation de marqueurs micro-satellites polymorphiques pour Microcyclus ulei, agent de la maladie sud américaine des feuilles de l'hévéa
Résumé : South American leaf blight caused by the ascomycete #Microcyclus ulei# is the most harmful disease of the rubber tree in Latin America and a potential threat to Asiatic and African natural rubber production. Until now, the variability of this fungus was assessed through observation of pathogenicity of isolates on a range of rubber tree clones with known resistance reactions. The present study describes the process used to design 11 microsatellite markers and evaluates their usefulness in detecting genetic polymorphism. Nine of these markers were polymorphic among six isolates from Brazil (with two to three alleles per locus) and five markers were polymorphic among four isolates from French Guiana (with two to four alleles per locus).
