摘要

摘要胭脂鱼(Coilia nasus)是一种重要的鱼类，在中国具有重要的商业价值。为了更好地管理渔业资源，制定可持续捕捞策略，保护该物种，利用11个微卫星位点多态性和mtDNA COI序列，对日本和中国两国的纳沙鲷进行了遗传多样性分析。共检测到40个COI单倍型和93个微卫星等位基因。mtDNA系统发育不支持种群划分，但mtDNA单倍型分布模式和基于微卫星的结构分析结果表明该物种存在一定程度的遗传隔离。种群遗传结构的缺乏可能导致其雌雄同体的生活史，地理距离和生境碎片化可能导致其种群隔离。因此，在日本和中国的取样居群可划分为4个地理/生态居群。

New insights on geographical/ecological populations within Coilia nasus (Clupeiformes: Engraulidae) based on mitochondrial DNA and microsatellites

Abstract The Coilia nasus is an important fish species, which is of commercial values in China. In order to manage the fisheries resources and the development of sustainable fishing strategies to protect this species, 11 microsatellite loci polymorphisms and mtDNA COI sequences were used to examine the genetic diversity of C. nasus in Japan and China. In total, the 40 COI haplotypes and 93 microsatellite alleles were detected. The mtDNA phylogeny did not support population grouping, but the distribution patterns of mtDNA haplotypes and the results of STRUCTURE analysis based on microsatellite indicated a degree of genetic isolation in this species. Our study suggested that the lack of a population genetic structure might result in its amphidromous life cycle, and the geographical distance and habitat fragments might cause isolated populations. Thus, the sampling populations of C. nasus in Japan and China could be divided as four geographical/ecological populations.

期刊介绍： Mitochondrial DNA Part A publishes original high-quality manuscripts on physical, chemical, and biochemical aspects of mtDNA and proteins involved in mtDNA metabolism, and/or interactions. Manuscripts on cytosolic and extracellular mtDNA, and on dysfunction caused by alterations in mtDNA integrity as well as methodological papers detailing novel approaches for mtDNA manipulation in vitro and in vivo are welcome. Descriptive papers on DNA sequences from mitochondrial genomes, and also analytical papers in the areas of population genetics, phylogenetics and human evolution that use mitochondrial DNA as a source of evidence for studies will be considered for publication. The Journal also considers manuscripts that examine population genetic and systematic theory that specifically address the use of mitochondrial DNA sequences, as well as papers that discuss the utility of mitochondrial DNA information in medical studies and in human evolutionary biology.
