| 英文摘要 | The soil microbiome plays an important role in carbon (C) and nitrogen (N) processing and storage and is influenced by rare earth elements (REEs), which can have both direct and indirect effects on plant metabolic processes. Using conventional physicochemical methods and metagenomic-based analyses, we investigated REEs effects on soil respiration, soil mineral N, soil microbial community structure and functional genes related to C and N metabolism. High doses of cerium (0.16 and 0.32 mmol kg- 1 soil) increased CO2 net production rate by 59 and 42%, and N2O net production rate by 255 and 609%, respectively, compared to no REEs. Similarly, high doses of lanthanum (0.16 and 0.32 mmol kg- 1 soil) increased CO2 net production rate by 47 and 39%, and N2O net production rate by 105 and 187%, respectively. Increased soil respiration from altered relative abundances of key soil microorganisms associated with soil N cycling and organic matter degradation and functional genes encoding enzymes involved in C and N metabolism, accelerated N mineralization. Elevated REEs levels substantially increased the relative abundances of functional genes related to cellulose, chitin, glucans, hemicellulose, lignin, and peptidoglycan degradation. REEs also influenced multiple functional genes associated with the N cycle. The abundance of genes responsible for organic N degradation and synthesis, such as asnB, gdh_K15371, glsA, and gs, increased with elevated cerium and lanthanum concentrations. Similarly, the abundances of denitrification genes, including narl, narJ, narZ, and nosZ, also rose with increasing amounts of cerium and lanthanum. However, the decrease in narB and nirB gene abundance with increasing REE concentrations was attributed to the reduction of nitrate to amino groups. Our findings highlight the influence of REEs on key soil microorganisms associated with soil N cycling and organic matter degradation and key functional genes in soil C and N metabolism, with implications for agriculture, environmental protection, and human health. |
