Development of 57 novel polymorphic microsatellite markers in half-smooth tongue sole (Cynoglossus semilaevis)

Abstract

Half-smooth tongue sole (Cynoglossus semilaevis) is a promising species for aquaculture in China. The wild population of C. semilaevis is under threat from environmental factors. Microsatellite markers are very suitable for assessing genetic diversity. Four microsatellite-enriched libraries of half smooth tongue sole (Cynoglossus semilaevis) were constructed, from which 57 polymorphic microsatellites were isolated and characterized. The polymorphism of these microsatellites was assessed by genotyping in 30 individual fish. The number of alleles ranged from 2 to 11, with an average of 4.614 alleles per locus. The values of observed and expected heterozygosities ranged from 0.1000 to 1.0000 and from 0.0966 to 0.8847 respectively. Polymorphism information content (PIC) ranged from 0.0905 to 0.862. These markers would be useful for population structure assessment, genetic linkage map construction and parentage analysis for this species.
