| 摘要 | Manila clam (Ruditapes philippinarum) is an important commercially marine bivalve, and its wild populations have been severely declining in the coast of China during the last decade. In this study, a set of 7 genomic simple sequence repeat (SSR), and 5 expressed sequences tag (EST)-derived SSR markers were analyzed on eight wild R. philippinarum populations to assess the genetic diversity and population differentiation. A total of 114 alleles were detected on 12 loci, and the number of alleles per locus in each population ranged from 2 to 11, and allelic richness per locus varied from 2.00 to 10.88 for each sample. The average of observed and expected heterozygosity ranged from 0.386 to 0.550, and from 0.533 to 0.707, respectively. Pairwise F-ST values indicated that all population pairs had significant genetic differentiation (overall F-ST = 0.242, P < 0.01). Cluster analysis using unweighted pair group method with the arithmetic mean (UPGMA) separated the eight populations into two groups. This study will shed light on the domestication and cultivation on population genetic diversity of R. philippinarum, and also provide the foundation for conservation of R. philippinarum germplasm resources in clam breeding practices.
