Isolation and characterization of polymorphic microsatellite loci from black snapper Sebastodes fuscescens (Houttuyn).

Black snapper Sebastodes fuscescens (Houttuyn) is an economocally important species. Fourty-five microsatellite loci were isolated from an enriched genomic library of S. fuscescens. Ten of these loci were polymorphic in a test population with alleles per locus ranging from 2 to 5, and observed and expected heterozygosities per locus from 0.21 to 1.00 and from 0.19 to 0.86, respectively. Three loci significantly deviated from Hardy-Weinberg equilibrium after Bonferroni correction and no significant linkage disequilibrium was found between pairs of loci. These polymorphic microsatellite loci would be useful for investigating genetic diversity of S. fuscescens and other related species. [ABSTRACT FROM AUTHOR]
