摘要

摘要:风菖蒲(Sillago aeolus)是菖蒲科的一种，是中国沿海地区分布广泛、具有重要科学和经济价值的种。它的种群遗传学尚未被研究过。本研究利用9个地点248个个体的线粒体控制区标记，对中国东南部沿海地区的风球菌群体遗传学进行了研究。种群多样性高，核苷酸多样性低。单倍型网络和NJ树均未发现与采样点对应的分支。海口种群与其他种群之间存在着不对称的基因流交换和显著的遗传差异。AMOVA结果显示遗传结构轻微，具有同质性。中性检验和错配分布揭示了近期的种群扩张事件。历史地理事件可能是人口内部同质性的原因。

Study on population genetics of Sillago aeolus (Perciformes: Sillaginidae) in the Coast of China

Abstract Sillago aeolus is a species from Sillaginidae, which is a widely distributed species with important scientific and economic value in the coast of China. Its population genetics have not been studied. This study investigated the population genetics of S. aeolus in the eastern and southern coast of China based on the mitochondrial control region markers obtained from 248 individuals of 9 locations. The population was characterized by a high population diversity with a low nucleotide diversity. There were no branches corresponding to the sampling sites according to the haplotype network and NJ tree. Recent asymmetric gene flow exchanges and significant genetic differences were detected between the Haikou population and the other populations. AMOVA result indicated slight genetic structures with homogeneity suggested. The neutral test and the mismatch distribution revealed a recent population expansion event. Historical geographic events may be the reason for the homogeneity within the population.

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.
