Characterization of nine novel microsatellite loci for the Venus clam (Cyclina sinensis)
Abstract
The Venus clam, Cyclina sinensis, is one of the most important bivalves in China marine aquaculture. Using (CA)15-enriched genomic libraries of this species, nine novel polymorphic microsatellite loci were isolated and characterized. The mean number of observed alleles per locus was 16 (range 8-24). The observed and expected heterozygosity ranged from 0.119 to 0.872 and from 0.626 to 0.931, respectively. Three loci had significant departure from Hardy-Weinberg equilibrium and non-significant linkage disequilibrium was found among all nine loci. These highly informative microsatellite markers should be useful for population genetic analyses of C. sinensis.
