Isolation and characterization of polymorphic microsatellite DNA markers in the Omono type of ninespine stickleback, genus Pungitius

We isolated and characterized 25 polymorphic microsatellite loci for the Omono type of ninespine stickleback, genus Pungitius, an endangered species in streams including agricultural canals in Japan. The number of observed alleles per locus ranged from two to 15 within 32 individuals each collected from three populations in the Omono River, and the values of observed and expected heterozygosities ranged from 0.031 to 0.906 and from 0.031 to 0.856, respectively. All loci conformed to the Hardy–Weinberg equilibrium. Genetic linkage disequilibrium analysis between all pairs of the loci showed no significant departure from the null hypothesis between any of the loci.
