Antibiotic resistance genes (ARGs) as emerging environmental contaminants exacerbate the risk of spreading antibiotic resistance. Natural organic matter (NOM) is ubiquitous in aquatic environments and plays a crucial role biogeochemical cycles. However, its impact on dissemination extracellular (eARGs) under sunlight exposure remains elusive. This study reveals that environmentally relevant levels NOM (0.1-20 mg/L) can significantly enhance natural transformation frequency model bacterium

Bacterial biofilms can enhance tolerance to antibiotics, however, antibiotic-resistance evolution in under environmental stressors via horizontal gene transfer remains unclear. This study investigated the natural transformation mediated by extracellular DNA (eDNA) at single-cell level stresses of tetracycline, sulfamethoxazole, and Zn²⁺ explore biofilms. The sub-minimal inhibitory concentrations (MICs) enhanced antibiotic resistance genes (ARGs) 1.01-fold 4.62-fold B. subtilis 6.94-fold A. baylyi biofilms, respectively, compared unstressed conditions; meanwhile, biofilm growth increased 1.29-fold 1.48-fold, with transformation. These results demonstrated that ARGs bacterial adaptability stresses. stimulated polysaccharide production 1.06–3.15 times, offering protection against penetration. They also induced reactive oxygen species membrane permeability 1.02–2.83 1.02–2.04 promoting Additionally, exogenous SOS response-related introduced eDNA were upregulated 1.03–7.06 times recipient cells, facilitating functional regulation. findings reveal critical role sub-MIC stressors, providing a theoretical basis for controlling spreads.
