Development of microsatellite loci for Pelophylax plancyi and cross-amplification in other ranid species

Abstract

Thirteen polymorphic microsatellite loci were obtained from the gold-striped pond frog, Pelophylax plancyi. The number of alleles per locus ranged from 5 to 13 with an average of 8.38. The observed and expected heterozygosities (HO and HE) ranged from 0.533 to 0.890 and from 0.620 to 0.897, with averages of 0.686 and 0.751, respectively. In order to assess interspecific amplification, all primer pairs were tested with the same PCR conditions on three other Pelophylax species: Pelophylax hubeiensis, Pelophylax fukienensis, Pelophylax nigromaculata and two species from the genus Hylarana and Hoplobatrachus, respectively. All of these loci can be amplified successfully in the Pelophylax species, with eight loci amplified in all species tested.
