摘　　要：外源抗生素抗性基因(Antibiotic resistance genes,ARGs)对土壤生态健康和农产品质量安全构成严重威胁,但ARGs在土壤-农作物系统中定殖机理不清、跨界迁移机制不明,直接制约了农业系统中细菌耐药污染的有效防控。本文简要论述农田系统ARGs目前赋存现状,系统综述外源ARGs在农田土壤和农作物中的动态演变特征及其与土壤特性的关联性,梳理了ARGs在土壤中侵入-持留-迁移的定殖分子机制以及揭示耐药菌与内生菌之间的交互过程及驱动因素,并提出关于未来农田ARGs环境行为和阻控研究的展望和建议。Exogenous antibiotic resistance genes(Antibiotic resistance genes,ARGs)pose a serious threat to soil ecological health and agricultural product quality and safety.However,the colonization mechanism of exogenous ARGs in the soil-crop system remains unclear,and the mechanisms of cross-border migration are not well understood,directly hampering effective control of bacterial resistance contamination in agricultural systems.This study briefly discussed the current status of ARGs in agricultural systems,systematically reviewed the dynamic evolution characteristics of exogenous ARGs in agricultural soil and crops,and their correlation with soil properties.It elucidated the colonization molecular mechanisms of ARGs in soil throughout the processes of invasion,persistence,drifted and clarified the interaction processes and driving factors between resistant bacteria and endogenous bacteria.Furthermore,it proposed prospects and recommendations for future research on ARGs fate and elimination control in agricultural fields.
