PRIMER NOTE Isolation and characterization of polymorphic microsatellite loci in nurse shark (Ginglymostoma cirratum)

We report on the development of nine polymorphic microsatellite loci in nurse shark (Ginglymostoma cirratum) using a combination of enriched and unenriched subgenomic libraries. Based on the small percentage of positive clones in the unenriched library (0.4%) it appears that microsatellites are very scarce in nurse shark genomes. Numbers of alleles at polymorphic loci ranged from two to 15; observed heterozygosity ranged from 0.17 to 0.90. We expect these loci to be useful for studies of breeding structure and paternity.
