作为微生物群落的丰富成员，病毒影响微生物死亡率、碳和营养循环以及食物网动态。尽管我们关于病毒群落的大部分信息都来自海洋系统，但越来越多的证据表明病毒在土壤中同样重要。在这里，我概述了土壤病毒宏基因组方法和土壤病毒生态学作为一个领域的现状，然后我强调了我们可以开始填补的现有知识空白。我们准备阐明土壤病毒对陆地生态系统过程的贡献，考虑到：跨营养尺度的全套潜在宿主、不同病毒复制策略的生态影响、与作物生产力等经济相关结果的联系，以及跨时空尺度和环境条件的可测量的原位病毒宿主种群动态。很快，我们将了解土壤病毒如何促进与有机物分解、碳和养分循环、温室气体排放和农业生产力相关的食物网。
As abundant members of microbial communities, viruses impact microbial mortality, carbon and nutrient cycling, and food web dynamics. Although most of our information about viral communities comes from marine systems, evidence is mounting to suggest that viruses are similarly important in soil. Here I outline soil viral metagenomic approaches and the current state of soil viral ecology as a field, and then I highlight existing knowledge gaps that we can begin to fill. We are poised to elucidate soil viral contributions to terrestrial ecosystem processes, considering: the full suite of potential hosts across trophic scales, the ecological impacts of different viral replication strategies, links to economically relevant outcomes like crop productivity, and measurable in situ virus-host population dynamics across spatiotemporal scales and environmental conditions. Soon, we will learn how soil viruses contribute to food webs linked to organic matter decomposition, carbon and nutrient cycling, greenhouse gas emissions, and agricultural productivity.
