摘要：

This study isolated and characterized 11 novel microsatellite markers for the commercially important swimming crab species, Portunus trituberculatus. Genetic diversity and population structure of two populations of P. trituberculatus in the East China Sea were assessed using these loci. The microsatellite markers produced 242 alleles, varying from 17 to 26 alleles per locus. In all the samples, the range of heterozygosity was 0.6324-0.9403 (observed) and 0.8998-0.9547 (expected). An F-statistic analysis revealed low genetic differentiation between the populations (mean F (ST) = 0.0197), with 98% of the variation resulting from the within-population component. In addition, cross-amplification was tested in two other portunid species, and we found that many loci yielded useful information. The high degree of polymorphism exhibited by the 11 microsatellites suggests that these markers will be useful for both aquaculture and studies of natural populations of the genus.
