聚球藻是海洋浮游植物群落的优势组分,是全球碳循环的主要参与者和初级生产力的主要贡献者。聚球藻病毒对聚球藻有较高的致死率,聚球藻病毒对聚球藻的裂解对碳的生物地球化学循环有十分重要的作用。对聚球藻病毒的宿主、分类和生活方式作了简介,综述了聚球藻病毒研究方法、生态分布特征、遗传多样性与宿主的关系及其进展,评述了不同基因标记物在聚球藻病毒分子生态学应用上的优缺点,最后提出了聚球藻病毒的研究展望。旨在为海洋病毒生态学,海洋碳循环的研究提供参考。
Cyanobacteria of the genus Synechococcus dominates the prokaryotic component of the picophytoplankton in the oceans,contributing to a significant portion of total marine primary production.Cyanophage accounts for a significant Synechococcus mortality,and cyanophage lysis thus plays an important role in global carbon biogeochemical cycling.On the basis of the summarization of characterization of cyanophages including the hosts,phage families and lifestyles,this review described and discussed the methods,cyanophages distribution,genetic diversity and interaction with hosts.The comparison of different gene markers which was widely used in cyanophage ecology was also presented.Finally we gave general outlook for the study of cyanophages,aiming to offer some references for the study of ecology of cyanophages and marine carbon cycling in the future.
