Eleven novel microsatellite markers for the Asian oyster Crassostrea ariakensis

Clones from four partial genomic libraries of the Asian oyster Crassostrea ariakensis were screened to reveal 64 microsatellite-containing sequences. Polymerase chain reaction primers were designed for 34 of these loci. Reactions were optimized for 11 primer pairs and markers were evaluated in eight family crosses and one wild population from northern China. Zero to three null alleles per locus were identified in family crosses, and two of the 11 loci showed allele frequency deviations from Hardy-Weinberg equilibrium in the wild population. These markers have proven useful for genetic studies of C. ariakensis.
