摘要
淡水和海水中存在的病毒被称为浮游病毒。它们是海洋和湖泊中最丰富的生物类群,是近年来才认识到的具有控制有害藻华(赤潮)、调节水生态系统结构、以纳米尺度驱动全球生物地球化学循环、特别是碳循环的一类不可忽视的战略生物资源。本文在综述淡水和海水病毒的多样性、感染类型、基因组分析、分布与丰度及其具有生物泵的生态学功能等研究进展的基础上,提出了研究对策和重点研究方向,认为建立进行淡水和海水病毒研究的技术平台与系统应成为我国争取该类生物战略资源的当务之急。
Viruses existing in freshwater and seawater are called planktonic viruses （virioplankton）. They are the most abundant biological group in the world＇s oceans and lakes, and are a kind of significant strategic bio-resources. Recently, the viruses have been recognized to have significant roles in the control of harmful water alga blooms （red tide） and in the regulation of water ecosystems, and considered as a key nanoscale driver in the global biogeochemical cycle, especially in the global carbon cycle. Based on the progress review for their diversity, infection types, genome analysis, distribution and abundance in freshwater and seawater, and their ecological function of bio-pump, the research countermeasures and priority research orientations have been suggested in the paper. The authors further propose that the urgent affairs for contesting the significant strategic bio-resources should be to establish the technological platform for studying the freshwater and marine viruses.
