Viruses play vital biogeochemical and ecological roles by (a) expressing auxiliary metabolic genes during infection, (b) enhancing the lateral transfer of host genes, and (c) inducing host mortality. Even in harsh and extreme environments, viruses are major players in carbon and nutrient recycling from organic matter. However, there is much that we do not yet understand about viruses and the processes mediated by them in the extreme environments such as hypersaline habitats. The Great Salt Lake (GSL) in Utah, United States is a hypersaline ecosystem where the biogeochemical role of viruses is poorly understood. This study elucidates the diversity of viruses and describes virus–host interactions in GSL sediments along a salinity gradient. The GSL sediment virosphere consisted of

病毒及其与高盐大盐湖细菌和古生菌的相互作用
病毒通过 (a) 在感染过程中表达辅助代谢基因,(b) 增强宿主基因的横向转移,以及 (c) 诱导宿主死亡来发挥重要的生物地球化学和生态作用。即使在恶劣和极端的环境中,病毒也是从有机物回收碳和养分的主要参与者。然而,我们对病毒及其在极端环境(例如高盐度栖息地)中介导的过程还有很多不了解。美国犹他州的大盐湖 (GSL) 是一个高盐度生态系统,对病毒的生物地球化学作用知之甚少。这项研究阐明了病毒的多样性,并描述了 GSL 沉积物中沿盐度梯度的病毒-宿主相互作用。GSL 沉积物大气圈由
