摘 要:低温环境分布最广,生物圈约80%以上的部分为常年低于5℃的低温地区,而在水环境(包括深海、极地海洋、海冰和高纬度湖泊等)中病毒的分布和含量是非常丰富的。在这些低温环境中,噬菌体在生态系统调控、全球生物地球化学循环(尤其是碳循环)、深海代谢和生物基因多样性保存等方面扮演着重要角色。该文主要对海洋和淡水湖泊中低温噬菌体的多样性进行简要综述。
关键词:海洋;淡水湖泊;低温噬菌体;多样性
 
Research advances on the diversity of cold-active phages in aquatic environment

Abstract: Low temperature environments are widely distributed. Over 80% of biosphere is below 5℃ all through the year. Viruses are abundant in the aquatic biosphere, including in the cold environments of the deep sea, polar oceans, sea ice and high-latitude lakes. Phages play important ecological roles in overall regulating of ecosystem global biogeochemical cycles (especially carbon cycle), deep-sea metabolism and a reservoir of the greatest genetic diversity on earth. Here, we briefly review the diversity of cold-active phages in marine and freshwater lakes.
Key words: marine; freshwater lakes; cold-active phages; diversity
