Genetic diversity of the rare plant species Phlox pungens (Polemoniaceae).

The genus Phlox is an ecologically diverse group of herbs and subshrubs with a center of diversity in western North America. A current focal study investigates population genetics of P. pungens Dorn, a rare species occurring in cold deserts of the Wyoming Basins Ecoregion in west central Wyoming. Samples of P. pungens were collected across the entire species range (including parts of the Green River and Wind River Basins), with care taken to include diversity relative to morphology (which exhibits geographic patterns). Microsatellite data have been generated for these populations (10 populations total), as well as for populations of additional Phlox species from the region (6 additional species, 7 populations total). We present these data and discuss their implications to our understanding of 1) genetic variation within P. pungens, including among the eastern and western sets of populations, and 2) genetics of P. pungens within the broader context of genetic diversity of Phlox. Results of this research may hold implications for the long-term conservation of the rare P. pungens, and they also contribute to broader work investigating taxonomic diversity of the genus Phlox.
