Abstract

Nine polymorphic microsatellite markers for the phytopathogenic fungus Colletogloeopsis zuluensis, the causal agent of an important stem canker disease of Eucalyptus, were isolated and characterized. Two methods, random amplified microsatellite sequences (RAMS) and fast isolation by AFLP of sequences containing repeats with modifications (M-FIASCO), were used to isolate the microsatellites. Primers for 28 prospective microsatellite regions were designed and nine of these were polymorphic for C. zuluensis. Allelic diversity ranged from 0.12 to 0.80 with a total of 37 alleles. These markers will be used in future to determine the population genetic structure of C. zuluensis isolates and to monitor their global movement.
