摘要

       土壤是抗生素抗性基因（ARGs）的重要储存库，但它们在不同生态系统中的潜在风险以及对人为土地利用变化的反应尚不清楚。 我们使用宏基因组方法和具有充分表征的元数据的数据集来研究三个原生生态系统的土壤 DNA 中的 ARG 类型和数量：阿拉斯加苔原、美国中西部草原和亚马逊雨林，以及后两者转化为农业的影响 和牧场，分别。

       Soil is an important reservoir of antibiotic resistance genes (ARGs), but their potential risk in different ecosystems as well as response to anthropogenic land use change is unknown. We used a metagenomic approach and datasets with well-characterized metadata to investigate ARG types and amounts in soil DNA of three native ecosystems: Alaskan tundra, US Midwestern prairie, and Amazon rainforest, as well as the effect of conversion of the latter two to agriculture and pasture, respectively.
