Isolation and characterization of microsatellite markers for Sabatia campestris (Gentianaceae), an Illinois state‐endangered plant

Sabatia campestris is a regionally endangered prairie plant. Eight polymorphic loci have been generated for S. campestris (Gentianaceae) using non‐enriched and enriched libraries. Polymorphism was quantified from an isolated population from central Illinois yielding mean observed and expected heterozygosities of 0.723 and 0.801, respectively. The number of alleles per locus for this population ranged from three to 25 with a median of 15.5. These genetic markers will be used to determine population genetic structure of Illinois populations as well as to estimate fine‐scale gene flow rates.
