Development and characterization of polymorphic microsatellite markers in the gray mullet (Mugil cephalus)

Author(s): T.-J. Xu, D.-Q. Sun, G. Shi and R.-X. Wang

Using an (AG)13 enriched genomic library of Mugil cephalus, 12 polymorphic microsatellite loci were isolated and characterized in a test population; the number of alleles ranged from 2 to 11. The observed and expected heterozygosities ranged from 0.2593 to 0.8966 and from 0.3047 to 0.8454, respectively. Two loci deviated from Hardy-Weinberg equilibrium; linkage disequilibrium among the 12 loci was non-significant. These polymorphic microsatellite loci will be useful for genetic diversity analysis and molecule-assisted breeding of the gray mullet.
