Abstract
The razor clam, Sinonovacula constricta, is an important commercial bivalve and a popular mollusca food in China. Twelve polymorphic microsatellite markers were isolated from the razor clam using a partial genomic library enriched for tandem repeat sequences of (CA)16, (GA)16. Polymorphisms of these loci were evaluated in a wild population of 30 individuals. The allele number of these polymorphic markers ranged from 5-15 per locus with an average of 9.333. Observed and expected heterozygosity values ranged from 0.192-1.000 and 0.219-0.906. Polymorphism information content ranged from 0.209-0.892 with an average of 0.704. Three loci significantly deviated from Hardy-Weinberg equilibrium after Bonferroni correction. No significant linkage disequilibrium was detected between these loci. This set of microsatellite loci are useful for genetic studies in S. constricta.
