DNA viruses are increasingly recognized as influencing marine microbes and microbe-mediated biogeochemical cycling. However, little is known about global marine RNA virus diversity, ecology, and ecosystem roles. In this study, we uncover patterns and predictors of marine RNA virus community- and "species"-level diversity and contextualize their ecological impacts from pole to pole. Our analyses revealed four ecological zones, latitudinal and depth diversity patterns, and environmental correlates for RNA viruses. Our findings only partially parallel those of cosampled plankton and show unexpectedly high polar ecological interactions. The influence of RNA viruses on ecosystems appears to be large, as predicted hosts are ecologically important. Moreover, the occurrence of auxiliary metabolic genes indicates that RNA viruses cause reprogramming of diverse host metabolisms, including photosynthesis and carbon cycling, and that RNA virus abundances predict ocean carbon export.

全球海洋 RNA 病毒的多样性和生态足迹。

DNA病毒越来越被认为影响海洋微生物和微生物介导的生物地球化学循环。然而，对全球海洋 RNA 病毒多样性、生态学和生态系统作用知之甚少。在这项研究中，我们揭示了海洋 RNA 病毒群落和“物种”水平多样性的模式和预测因子，并将它们从极点到极点的生态影响背景化。我们的分析揭示了 RNA 病毒的四个生态区、纬度和深度多样性模式以及环境相关性。我们的研究结果仅部分平行于共同采样的浮游生物，并显示出出乎意料的高极性生态相互作用。RNA病毒对生态系统的影响似乎很大，因为预测的宿主在生态上很重要。而且，
