Isolation and characterization of 24 polymorphic microsatellite loci in Sepioteuthis lessoniana

Owing to their codominant, multiallelic, and highly polymorphic nature, microsatellite markers have been used widely in population genetics and biological resource conservation studies. To investigate the genetic structure of Sepioteuthis lessoniana, we developed 24 microsatellite DNA markers and assessed the polymorphism of each locus in a wild S. lessoniana population. The number of alleles per locus ranged from 4 to 26, and the observed and expected heterozygosities varied from 0.188 to 1.000 and 0.392 to 0.959 with an average of 0.675 and 0.852, respectively. These microsatellite loci will be useful tools in future studies of population genetic structure in this species.
