Isolation and characterization of variable microsatellite loci in Lilium philadelphicum (Liliaceae)

Here we describe the characterization of six polymorphic microsatellite loci for Lilium philadelphicum (Liliaceae). Polymorphism levels ranged from 7 to 30 alleles per locus with a mean number of 15 alleles per locus. Observed heterozygosity (H_O) ranged from 0.17 to 0.82 and did not deviate from Hardy–Weinberg expectations in the three western Montana populations included in the analysis. These loci are proving useful in studying gene flow between populations of this species distributed across its range in North America.
