Oyster (Crassostrea plicatula) is widely distributed in coastal areas of China. We developed and evaluated simple sequence repeat (SSR) markers from expressed sequence tags (ESTs) of Crassostrea gigas and to amplify EST-SSR in C. plicatula. Characteristics of eight EST-SSR loci were investigated using 37 wild-type C. plicatula individuals. The number of alleles per locus ranged from four to six. The observed heterozygosity (H (O)) ranged from 0.1892 to 0.7027 (0.3919 on average) and the expected heterozygosity (H (E)) ranged from 0.6068 to 0.7656 (0.7039 on average) (P < 0.05). The average observed heterozygosity was much lower than the average expected heterozygosity. All loci except C15 departed from Hardy-Weinberg equilibrium (P < 0.05) significantly. Contribution of the eight EST-SSR primers presented here will provide necessary and powerful molecular tools for management and conservation studies on the species of oysters in the future.
