Popis: Turbot (Scophthalmus maximus) is a flatfish species commercially important for aquaculture. In this study, we generated a microsatellite-enriched genomic DNA library for Scophthalmus maximus, and then isolated and characterized 45 microsatellite loci by genotyping 30 individuals. The observed number of alleles ranged from 2 to 19 with an average of 6.24, while the effective number of alleles ranged from 1.30 to 11.11 with an average of 3.66. The expected heterozygosities varied from 0.235 to 0.925 4 and Polymorphie information content ranged from 0.2044 to 0.903 3, with an average of 0.622. Twelve loci deviated significantly from Hardy-Weinberg equilibrium, and no significant linkage disequilibrium was observed between any pair of loci after Bonferroni correction. In cross-species amplification, five flatfish species (Paralichthys lethostigma, Verasper moseri, platichthys stellatus, Hippoglossoides dubius and Cynoglossus semilaevis) showed at least one Polymorphie locus. These Polymorphie microsatellite loci should prove useful for Population analysis of turbot and other related species.
