Abstract Despite advances in dispersal mechanisms and risk assessment of antibiotic resistance genes (ARGs), how plants influence ARG contamination agricultural soils remains underexplored. Here, the impacts plant species diversity on ARGs mobile genetic elements (MGEs) three are comprehensively investigated a pot experiment. The results indicate that increased reduces MGEs abundance by 19.2%–51.2%, whereas exhibit inconsistent soil‐dependent effects. Potential bacterial hosts harboring abundant have greater relative than nonhosts, both their richness cumulative reduced diversity. Notably, inhibited present other hosts. enriched compounds root exudates due to play more important role metabolic network contribute rebalancing potential nonhosts. An independent test using pure organics reveals higher resource diversity, resulting from mobility high‐risk ARGs. This study highlights resource‐mediated mitigation risks posed indicates ensuring is promising strategy for controlling agroecosystems.

The rise of antibiotic-resistant soil microbial communities is a critical global issue. Evidence suggests that heavy metals can select or co-select for tolerance to and antibiotics in bacteria, but it unclear if this varies with land use. We tested the potential bacterial develop resistance copper (Cu) tetracycline (Tet) after amending soils from pristine forests, contaminated agricultural lands 3000 mg kg-1 Cu 6000 tetracycline, separately. Results showed unamended forest had highest initial Cu, while exhibited tetracycline. inducibility amendment varied by In significantly increased resistance, as indicated community tolerance, likely due higher biodiversity. did not induce tetracycline-resistance, unchanged possibly because existing metal pollution compromised pollution. soils, developed slowly, becoming evident only 42 days. These findings reveal significant differences environmental risks related across different uses, highlighting need systematic studies on mechanisms metal-contaminated their human health implications.
