Premise Of The Study:
Microsatellite markers were identified and characterized to study the genetic diversity and structure, conservation status, taxonomy, and biogeography of subspecific taxa and populations of Campanula pyramidalis (Campanulaceae).
Methods And Results:
Eleven microsatellite markers were developed from genomic libraries enriched for di- and trinucleotide repeats. A total of 80 alleles were observed in the tested natural population. The number of alleles per locus, observed heterozygosity, and expected heterozygosity ranged from four to 13, 0.217 to 0.913, and 0.521 to 0.895, respectively.
Conclusions:
The new microsatellite markers will be useful for studying genetic diversity and structure as well as for better assessing the conservation status of subspecific taxa and populations of C. pyramidalis. Furthermore, a set of seven loci was successfully cross-amplified in C. secundiflora and C. versicolor and will be of great value for addressing unsolved taxonomic and biogeographic issues within the C. pyramidalis species complex.
