چکیده انگلیسی
Microsatellites are powerful markers to infer population genetic parameters. Here, 13 microsatellite loci isolated from a genomic and a cDNA library of Cryphonectria parasitica were used to characterize the genetic diversity and structure of four French populations. Twelve of these loci were polymorphic within populations, and average gene diversity (He) was estimated to be 0.35. There was a lower genetic diversity in a south-eastern population relative to three south-western populations. In these three populations, microsatellite genotypic diversity was higher than vegetative compatibility type diversity. A high genetic differentiation (GSTÂ =Â 0.27) suggested a low gene flow and/or founder effects of French populations which are in agreement with low dispersal of spores and different introductions of this species in southern France. This study demonstrates the significance of these microsatellite loci to assess gene flow and reproductive system in this important pathogen.
