Genetic relationships among strains of Xylella fastidiosa from RAPD-PCR data
1995
Pooler, M.R. | Hartung, J.S.
Genetic relationships among 11 Xylella fastidiosa strains isolated from mulberry, almond, ragweed, grape, plum, elm, and citrus were determined by random amplified polymorphic DNA (RAPD). Twenty-two 10-base primers amplified a total of 77 discrete polymorphic bands. Phenetic analysis based on a similarity matrix corresponded well with previous reports on X. fastidiosa RFLP-based similarity relationships, indicating that RAPD-PCR amplification products can be used as a reliable indicator of genetic distance in X. fastidiosa. Cladistic analysis suggests the existence of five groups of X. fastidiosa: the citrus group, the plum-elm group, the grape-ragweed group, the almond group, and the mulberry group.
