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 risks in different ecosystems and their response to anthropogenic land use changes are unclear. We use metagenomics methods and data sets with well-characterized metadata to study the types and amounts of ARGs in the soil DNA of three native ecosystems: Alaska tundra, American Midwestern grasslands, and Amazon rainforest, and the latter two are converted to agriculture The impact and pasture, respectively.
