Development and characterization of microsatellite DNA markers for the Alpine plant species Campanula thyrsoides

We isolated and characterized eight polymorphic microsatellite markers for the Alpine plant species Campanula thyrsoides (Campanulaceae). Number of alleles per locus ranged from six to 12 and the observed heterozygosity was between 0.529 and 0.900. Observed vs. expected heterozygote deficits were significantly different in one out of eight loci following Bonferroni's correction for multiple tests. We did not find evidence for linkage disequilibrium between locus pairs. The microsatellite markers are being used for the study of genetic variation and gene flow within and among populations of C. thyrsoides in the Swiss Alps.
