Phylogeography and conservation of American ginseng (Panax quinquefolius L., Araliaceae).

We investigated the post-glacial history of American ginseng (Panax quinquefolius L., Araliaceae), native medicinal forest understory species. We tested the hypothesis that the geographic range of American ginseng populations is subdivided into eastern and western lineages as often observed in other taxa. Additionally, we looked for center of genetic diversity in the area of Southern Appalachian Mountains, the presumed location of glacial refugia. Using variation in chloroplast DNA sequences and nuclear microsatellite data, we documented surprisingly weak geographic chloroplast lineage structure across ginseng’s geographic range. As expected, the area of greatest genetic diversity is in the Appalachian Mountains. We identified unique chloroplast haplotypes further North and West than expected. This finding suggests that there may have been glacial refugia outside of the Southern Appalachian Mountains. We will discuss our effort to apply our results to conservation efforts and management of ginseng by the US FWS.
