Isolation and characterization of 40 polymorphic microsatellite markers from Parambassis siamensis

We isolated and characterized a total of 40 polymorphic microsatellite loci from the genome of Parambassis siamensis. Flanking Polymerase Chain Reaction primers were developed and used to show that all loci were polymorphic with the number of observed alleles per locus in 32 individuals ranging from 2 to 29. The observed heterozygosity ranged from 0.063 to 0.969, while the expected heterozygosity varied from 0.062 to 0.960. All loci conformed to Hardy-Weinberg equilibrium, none of the loci combinations showed significant linkage disequilibrium, and no loci showed evidence of null alleles. These 40 microsatellite loci should be useful for conducting future investigations into the genetic differentiation and structure of populations of P. siamensis.
