摘要: The construction of a genetic linkage map and evaluation of population genetic diversity both require large numbers of polymorphic molecular markers. In the present study, we report 31 polymorphic microsatellite markers, of which 28 were isolated from two repeat-enriched libraries constructed from genomic DNA, and three were detected in two genes (MCH-R1 and MCH-R2) of barfin flounder (Verasper moseri). A total of 94 alleles were detected with an average of 3.0 alleles per locus. The number of alleles, observed and expected heterozygosity per locus ranged from two to six, from 0.30 to 1.00 and from 0.33 to 0.78, respectively. Three loci significantly deviated from Hardy-Weinberg equilibrium after Bonferroni correction (P < 0.0016) and no significant linkage disequilibrum between pairs of loci was found. Cross-species amplification of these markers was evaluated using the closely related species spotted halibut (Verasper variegatus). This study will potentially be useful for stock management, constructing of a genetic linkage map, mapping economically important quantitative trait loci (QTL), and studying the population genetic diversity of barfin flounder (Verasper moseri).
