Isolation and characterization of 26 polymorphic microsatellite loci in golden mahseer, Tor putitora (Teleostei, Cyprinidae) and their cross-species amplification in four related species

摘要

Twenty six polymorphic single-locus microsatellite loci were developed in golden mahseer, Tor putitora. The number of observed alleles per locus ranged from 5 to 16. The observed and expected heterozygosities ranged from 0.2721 to 0.9830 and from 0.4631 to 0.9216, respectively. No significant linkage disequilibrium was detected among the loci. Eight loci showed significant deviation from Hardy-Weinberg equilibrium, but none of them had evidence for null alleles. Twenty-four primer pairs cross-amplified each in Tor khudree and Naziritor chelynoides and 25 each in T. tor and T. mosal mahanadicus. These microsatellite loci should be useful for genetic diversity studies and conservation of golden mahseer and its closely related species.
