海洋鱼类种群基因组学研究进展

Research Progress on Population Genomics of Marine Fishes

近年来,高通量测序技术的发展及大数据分析能力的提高使得生物基因组水平上的研究日趋广泛。通过基因组测序、单核苷酸多态性识别、种群转录组学研究等方法,有助于进一步了解生物群体内部的适应性状相关基因的进化历程及调控机制,对于理论研究与生产实际均具有重大意义。通过海洋鱼类种群基因组学的研究,可以加深对于微观进化的重要环节,如遗传分化的产生、杂交带的维系及物种形成等机制的理解。因此,相关研究将有助于人们更好地理解海洋生物的进化过程,并且为水产养殖业的发展及海洋渔业资源的管理和保护提供理论依据。

Over the recent years,advances in high-throughput sequencing and big data analysis have facilitated genome-wide researchin many species. Using the methods of genome sequencing,single nucleotide polymorphism（SNPs）analysis and population transcriptomics,the evolutionary progress and regulatory mechanisms of adaptive genetic variation were understood in more details,which poses greatsignificance for theoretical research and productive practice. Furthermore,research on population genomics will deepen our understandingof important events in microevolution such as population divergence,hybridization and speciation. Therefore,the related research would beconducive for us to better understand the evolution of marine organisms,and provide theoretical evidences for development of aquaculture andmanagement of marine fishery resources.
