Fourteen microsatellite loci for the Chinese medicinal plant Epimedium sagittatum and cross-species application in other medicinal species.

Epimedium sagittatum is a well-known medicinal plant as well as potential ground cover and ornamental plant. A total of 14 polymorphic microsatellite markers were developed for use in taxonomy, phylogenetics and conservation genetics. Markers were presented between two and eight alleles per locus. The observed heterozygosity (H(O) ) and expected heterozygosity (H(E) ) ranged from 0.03 to 0.81 and from 0.05 to 0.81, respectively. Cross-amplification among other four medicinal species revealed promising results in three to six polymorphic loci. These microsatellite loci contributed to the limited number of useful markers currently available for E. sagittatum.
