The soil bacterial metagenome under the exposure of diverse MPs
MPs have been reported to influence the soil bacterial composition and gene expression, thus affect the soil carbon turnover. However, the influence of diverse MPs on soil carbon dynamics, as well as the role of soil bacterial metabolism, remains unclear. Here, we established a gradient of MPs diversity to examine its impact on soil dissolved organic matter, integrating metabolomics and metagenomics to assess the bacterial contributions to dissolved organic matter transformation.
