| Abstract: |
| The spread of antibiotic resistance genes（ARGs）in the soil-vegetable systems threatens ecological environments and the safety of vegetable quality. Additionally, consuming vegetables containing ARGs can further endanger human health. This paper provides a comprehensive review of the migration processes and mechanisms of ARGs in soil-vegetable systems. The migration process involves interactions between microbial communities. The paper analyzes the factors influencing the spread and diffusion of ARGs in soil-vegetable systems, including antibiotic selective pressure, non-antibiotic pollutants, soil types, and vegetable varieties. It systematically summarizes the current methods for reducing ARGs in the soil, primarily including source reduction of ARGs input through composting, biological reduction, and physicochemical reduction（such as the addition of soil amendments）. Finally, based on the current research gaps, the paper proposes future research directions regarding the migration mechanisms, influencing factors, and reduction methods of ARGs, aiming to provide a basis for risk prevention and control of ARGs in soil-vegetable systems. |
