American ginseng (Panax quinquefolius L., syn. Panax quinquefolium) is an herbaceous perennial plant native to eastern North America that is both harvested from the wild and cultivated in farm and woodlot settings to supply the international market. We describe the development of microsatellite markers to better characterize Panax quinquefolius population structure and phylogeography. We developed and tested 12 microsattelite loci, scored as 106 psuedo-dominant alleles due to the tetraploid nature of P. quinquefolius. We employed the newly developed markers to characterize population structure of field sampled populations from 13 states in comparison with commercially cultivated samples. Results reveal distinct phylogeographic and population structuring as well as a high degree of selfing in this CITES protected species.
