Antibiotic resistance gene pollution in the environment has been identified as a potential contributor to the global issue of antibiotic resistance prevalence, creating a need to identify and characterize environmental reservoirs for antibiotic resistance genes. Because many polluted environments have been shown to contain elevated levels of antibiotic resistance genes, agriculturally based pesticide bioremediation systems called 'biobeds' could serve as environmental reservoirs for antibiotic resistance genes, although this has never been extensively explored. Metagenomic and metatranscriptomic analyses of an on‐farm biobed system sampled before and after a season of pesticide use demonstrated that in situ pesticide applications applied to biobeds can enrich for multidrug, sulphonamide, aminoglycoside and beta‐lactam resistance genes. Additionally, this study demonstrated an enrichment for genes associated with gene mobilization, such as genes involved in horizontal gene transfer and plasmid mobility, as well as transposons and integrases.
