| Abstract | Antibiotic resistance genes (ARGs) and virulence factors (VFs) in soils represent a significant threat to ecological security and human health. The carbon-rich soil formed by manure fertilization provides an energy source for soil microbes. However, we still know little about how microbial-dominated carbon metabolism affects ARGs and VFs proliferation in soils subjected to long-term fertilization and irrigation practices in wheat-maize system. Here, we investigated soil microbial carbon metabolism, ARGs and VFs distribution, and microbial composition in soils under 9-year of different fertilization and irrigation managements during wheat growing period. Results showed that manure (M) increased total abundance of soil ARGs by 5.9 %–8.0 % and 2.1 %–4.8 % and VFs by 5.4 %–7.5 % and 2.0 %–4.9 % compared to no fertilizer (CK) and NPK fertilizer (C), respectively, regardless of irrigation. M enriched more number of ARGs and VFs types, and increased abundance of host microbes involved in carbon fixation and carbon degradation, such as Streptomyces, Lysobacter and Agromyces. M increased abundance of carbohydrate-active enzymes (CAZymes) and carbon cycle functional pathways, as well as microbial carbon metabolism capacity. Partial least squares path modeling and correlation analysis showed that microbial diversity, CAZymes, carbon cycle functional pathways (particularly carbon fixation and degradation) and microbial carbon metabolism capacity of microbial community had direct positive effects on the proliferation and spread of ARGs and VFs. In conclusion, our results highlight the importance of microbial mediated carbon metabolism in driving the dissemination of ARGs and VFs in soils under long-term manure application. |
