Isolation and characterization of microsatellite markers in Ruditapes philippinarum.
Ruditapes philippinarum is considered a commercially valuable species, which is commonly found in tidal flats along West Pacific coasts. In China, it is mainly distributed in the southeast sea. In this study, 16 novel microsatellite loci from the R. philippinarum genome were developed, using the protocol of fast isolation by amplified fragment length polymorphism of sequence containing repeats. Thirty-two wild-caught individuals were used to evaluate the degree of polymorphism of these markers. Our results show that there were 10 polymorphic loci and 6 monomorphic loci. The number of alleles per locus and the polymorphism information content ranged from 2 to 6 and from 0.199 to 0.751, respectively. The observed and expected heterozygosities varied from 0.1333 to 0.6207 and 0.1603 to 0.7412, respectively. Of all loci, only one locus was found to deviate significantly from Hardy-Weinberg equilibrium after Bonferroni correction. The loci identified here will provide useful information for future population genetic studies of R. philippinarum.
