To understand the genetic variability of the tetraploid fern Ceratopteris thalictroides (Parkeriaceae), we described 30 polymorphic microsatellite markers obtained using the restriction site-associated DNA (RAD) tag sequencing technique. A total of 26 individuals were genotyped for each marker. The number of alleles per locus ranged from 4 to 10, and the expected heterozygosity and the Shannon-Wiener index ranged from 0.264 to 0.852 and 0.676 to 2.032, respectively.
Nine microsatellite DNA markers were developed and characterized for Siganus oramin by the 5'-anchored polymerase chain reaction technique. A total of 42 alleles were identified in 30 individuals, and the number of alleles per locus ranged from 3 to 7, with an average of 4.7. The observed and expected heterozygosity per locus ranged from 0.5333 to 1.0000 and from 0.5254 to 0.8474, respectively, with an average of 0.7422 and 0.6906, respectively.
We isolated and characterized 22 polymorphic microsatellite loci in the crimson snapper (Lutjanus erythropterus) using a (GT)13-enriched genomic library. We found three to 15 alleles per locus, with a mean of 6.68. The observed and expected heterozygosities ranged from 0.087 to 0.978 and from 0.125 to 0.904, respectively, with averages of 0.576 and 0.650, respectively. Only three loci showed significant deviation from the Hardy-Weinberg equilibrium after Bonferroni correction. Four loci showed evidence for null alleles.
