Viruses are now recognized as important players in microbial dynamics and biogeochemical cycles in the oceans. Yet, compared with aquatic ecosystems, virus discovery in terrestrial ecosystems has been challenging partly due to the inherent complexity of soils. To expand our understanding of soil viruses and their putative contributions to soil microbial processes, we analysed metagenomes of community-level virus-enriched suspensions by tangential flow filtration obtained from two French agricultural soils. We found viral sequences representing a total of 239 viral operational taxonomic units that corresponded to 29.5% of the mapping reads in the metagenomic datasets. The analysis of their genomic sequences revealed novel virocell metabolic potential with implications to virus–host interactions, carbon cycling, plant-beneficial functions in the rhizosphere, horizontal gene transfer and other relevant microbial strategies applied to survive in soils.

通过富含病毒的土壤宏基因组分析揭示农业土壤中新的病毒细胞代谢潜力

病毒现在被认为是海洋微生物动力学和生物地球化学循环的重要参与者。然而,与水生生态系统相比,在陆地生态系统中发现病毒一直具有挑战性,部分原因在于土壤固有的复杂性。为了扩大我们对土壤病毒及其对土壤微生物过程的假定贡献的理解,我们通过从两种法国农业土壤中获得的切向流过滤分析了群落水平的富含病毒的悬浮液的宏基因组。我们发现病毒序列代表总共 239 个病毒操作分类单元,对应于宏基因组数据集中 29.5% 的映射读取。对其基因组序列的分析揭示了新的病毒细胞代谢潜力,对病毒-宿主相互作用、碳循环、
