Isolation and characterization of new polymorphic microsatellite markers from the cuttlefish Sepiella maindroni (Cephalopoda; Sepiidae).

Fifteen new polymorphic microsatellite loci were developed for the cuttlefish Sepiella maindroni. In 32 individuals from a wild population of coastal Ningde, Fujian Province, China, the number of alleles at these loci varied between 2 and 12, with an average of 5.86. The mean observed and expected heterozygosities were 0.6917 and 0.5993, respectively. Among these polymorphic microsatellite loci, 4 (SM2, SM19, SM40, and SM81) significantly deviated from Hardy-Weinberg equilibrium after sequential Bonferroni's correction. All of them were in linkage equilibrium. These microsatellite loci would be useful for evaluating the effect of releasing on extant S. maindroni populations as well as for investigating genetic diversity and population structure of this species.

Development of new polymorphic microsatellite markers in topmouth culter (Culter alburnus) and determination of their applicability in Culter mongolicus.

Fifteen new polymorphic microsatellite markers were developed for Culter alburnus. In 32 individuals representing a wild population of the Danjiangkou Reservoir, Hubei, China, the number of alleles at these loci varied between 2 and 10, with an average of 5.5. The average observed and expected heterozygosities were 0.664 and 0.681, respectively. The polymorphism information content of 11 loci was more than 0.5 whereas that of the other 4 loci was less than 0.5 but more than 0.25. In addition, the genomes of 30 C. mongolicus individuals were successfully amplified with these primer pairs, indicating that the primer pairs were applicable for the related species, C. mongolicus.
