One hundred nuclear-encoded microsatellites from a genomic library of red drum (Sciaenops ocellatus) were isolated and characterized. Eight microsatellites had tetranucleotide motifs; 92 had dinucleotide motifs. The average number of alleles per microsatellite (sample of 22-24 fish) was 17.7 (range = 2-30); gene diversity averaged 0.796 (range = 0.227-1.000). Following Bonferroni correction, genotype frequencies at 90 microsatellites did not deviate significantly from Hardy-Weinberg equilibrium expectations. Occurrence of null alleles was inferred at 15 microsatellites; alleles differing by only a single base were observed at 11 microsatellites. The microsatellites developed should prove useful for population-genetic studies of 'wild' red drum and in construction of a genetic map.
从红鼓鱼(Sciaenops ocellatus)的基因组文库中分离和鉴定了 100 个核编码微卫星。8 个微卫星具有四核苷酸基序;92 个具有二核苷酸基序。每个微卫星(22-24 条鱼样本)的平均等位基因数为 17.7(范围为 2-30);基因多样性平均为 0.796(范围为 0.227-1.000)。经过 Bonferroni 校正后,90 个微卫星的基因型频率与 Hardy-Weinberg 平衡预期没有显著偏离。在 15 个微卫星中推断出存在无效等位基因;在 11 个微卫星中观察到仅相差一个碱基的等位基因。开发的微卫星应该对“野生”红鼓鱼的种群遗传研究以及遗传图谱的构建有用。
