Isolation and characterization of microsatellite loci for a hyper-rare cliff endemic, Erigeron lemmonii, and a more widespread congener, Erigeron arisolius (Asteraceae)

We identified eight novel polymorphic microsatellite loci in Erigeron lemmonii and nine novel polymorphic microsatellite loci in Erigeron arisolius. Of these, three loci developed for E. arisolius cross-amplified E. lemmonii DNA and four loci developed for E. lemmonii cross-amplified E. arisolius DNA. This set of 17 loci will be used to analyze patterns of genetic structure in populations of these two Erigeron species in southeastern Arizona with the ultimate goal of comparing patterns of genetic structure within a hyper-rare cliff endemic (E. lemmonii) to those of a more widespread congener (E. arisolius).
