中国太平洋鲍群体与日本太平洋鲍群体杂交所获得的杂交种具有杂种优势,在我国的养殖生产中得到了广泛的应用。中国和日本鲍群体信息位点的鉴定对于太平洋鲍遗传资源的保护和杂种优势的研究具有重要意义。SNPs具有基因组丰度高、冗余度低的优点,在遗传学研究中受到广泛关注。本研究通过对太平洋鲍基因组测序数据的筛选,发现了32个具有群体信息潜力的SNP,并成功开发了其中的17个SNP标记。经过进一步的评估,5个SNPs显示两个群体之间的等位基因频率存在显著差异。这些SNPs可作为群体信息标记用于野生和养殖太平洋鲍遗传结构变化的评估以及该物种杂种优势的研究。
Hybrids produced by crossing between China and Japan Pacific abalone populations exhibited heterosis and have been applied extensively in aquaculture production in China. Identification of population informative loci for China and Japan populations is important for the genetic resource conservation and our understanding of heterosis in Pacific abalone. With the advantage of high genomic abundance and low redundance, SNPs have gained much interest in genetic studies. In this study, through screening the genome sequencing data of Pacific abalone, 32 potential population informative SNPs for China and Japan populations were found. Then 17 of them were successfully developed as SNP markers. After further evaluation, five SNPs showed significant differences in allele frequencies between the two populations. These SNPs could be used as population informative markers in the assessment of genetic structure changes in both wild and cultured Pacific abalone, and also in the studies on heterosis of this species.
