两极占据地球生物圈表面积的14%,共同组成了地球上独特的冰冻生物圈。南极是被南大洋包围着的巨大大陆,受南极绕极流所影响。而北极则是由欧、亚、北美三洲大陆包围着的北冰洋以及大量分散的岛屿所组成。极地海洋生物圈主要包括海水、海冰两大生态系统,而海冰是在两极地区存在的一个独特的生态系统。极地的海洋、海冰、冰下湖泊等环境中包含了大量的未知病毒和作为其主要宿主的微生物群落,是全球生物地球化学循环重要驱动力之一。本文对近十年来在南北极海洋环境中病毒多样性的研究进展进行综述,其中大多数的病毒多样性是随着宏基因组学技术的进步而被人所知的。目前对极地海洋双链DNA病毒组已有较好的认识,而对单链DNA病毒组和RNA病毒组的认识还非常有限。总体来说,对于极地海洋病毒认识还处在初级阶段,仍然存在大量未知的科学问题等待我们去探索。
