ABSTRACT
BACKGROUND:
Meretrix petechialis is one of the commercially important marine bivalves. In this study, we selected six highly polymorphic EST-derived microsatellite markers to assess the genetic diversity and population differentiation on nine wild populations of Meretrix petechialis.RESULTS:
The number of alleles detected per-locus ranged from 4 to 30 (mean NA = 27.5) with a total of 165 alleles. The mean value of observed and expected heterozygosities varied from 0.717 to 0.861 and from 0.797 to 0.856, respectively. Meanwhile, the result of Neighbor-joining and overall FST = 0.214 (P < 0.01) reveled that M. petechialis populations from GX are the farthest populations, a certain degree of genetic variation among individuals in each population and the genetic differentiation is significant.CONCLUSIONS:
GX population has high genetic diversity among individual, and there are certain differences in genetic characteristics among different populations. This study will provide a basis for the domestication and cultivation of genetic diversity of M. petechialis population and the protection of clam germplasm resources.Key words
