摘要

病毒是海洋生态系统中丰度最高的生命形式,其中超过90%属于浮游细菌(细菌和古菌)病毒,是海洋生态系统的重要参与者和海洋生物地球化学循环的重要驱动力。作为海洋浮游细菌主要的致死因子之一,病毒通过裂解宿主释放出大量的有机物和营养盐,调控宿主群落的代谢行为,进而影响生物地球化学循环。同时,伴随侵染的发生,病毒挟持宿主细胞的代谢系统完成自身的生命周期,从而改变宿主胞内的代谢途径和代谢产物。概述了病毒在个体层面和群落层面对海洋浮游细菌代谢的影响,及其对海洋元素循环的作用,评估了气候变化、环境因子对病毒调控细菌代谢的潜在影响,有助于人们对微生物参与的海洋生物地球化学循环的全面认识。

Abstract

Viruses are by far the most abundant entities in marine environments, and are mainly phages that infect bacteria and archaea, which also are a significant component of marine ecosystem and a major force behind marine biogeochemical cycles. As a major source of mortality, viral lysis can release highly labile cellular components, both organic matters and inorganic nutrients, regulating the metabolism of its hosts and influencing the biogeochemical cycles. During infection, viruses could hijack the metabolic system of hosts for its own propagation, thereby changing the metabolism and metabolites of host cells. This paper summarized the effects of viruses on the metabolism of marine bacterioplankton at both the cellular and community level, and its influence on the cycling of ocean elements. Then, the potential impact of environmental factors was assessed on the influence of viruses upon bacterial metabolism. This paper will contribute to a comprehensive understanding of the role of microbes within marine biogeochemical cycles.

Key words： Marine virus; Marine bacteria; Metabolism; Virus-host interaction.
