日本将湖相红鲑(Oncorhynchus nerka)列为濒危物种,尽管关于其种群结构的遗传信息很少。为了阐明日本种群的遗传多样性和结构,以评估瓶颈效应和濒危物种,我们分析了日本640条湖产红鲑和阿拉斯加伊纳湖80条溯河产卵红鲑的线粒体DNA(mtDNA)ND5区和45个单核苷酸多态性(SNP)。日本人群的mtDNA和SNPs的遗传多样性显着低于Ikonna湖人群。此外,所有日本人群的SNP位点偏离HWE。尽管遗传多样性低,SNP分析结果表明,日本人口被显著分为三组。这表明,日本红鲑鱼种群应作为濒危物种进行保护,并受到孵化计划和移植的遗传干扰。
Lacustrine sockeye salmon (Oncorhynchus nerka) are listed as an endangered species in Japan despite little genetic information on their population structure. In order to clarify the genetic diversity and structure of Japanese populations for evaluating on the bottleneck effect and an endangered species, we analyzed theND5region of mitochondrial DNA (mtDNA) and 45 single nucleotide polymorphisms (SNPs) in 640 lacustrine sockeye salmon in Japan and 80 anadromous sockeye salmon in Iliamna Lake of Alaska. The genetic diversity of the Japanese population in both mtDNA and SNPs was significantly less than that of the Iliamna Lake population. Moreover, all Japanese populations had SNP loci deviating from the HWE. In spite of low genetic diversity, the SNP analyses resulted that the Japanese population was significantly divided into three groups. These suggest that Japanese sockeye salmon populations should be protected as an endangered species and genetically disturbed by the hatchery program and transplantations.
