Antibiotics and copper drive compartment-specific dysbiosis and functional reprogramming in tomato microbiomes

Plant-associated microbiomes help sustain plant immunity and productivity, yet the degree to which agricultural antimicrobials reshape these microbial networks and alter disease outcomes remains poorly characterized. Here, we quantified how chemical inputs such as copper and streptomycin trigger distinct, compartment-specific dysbiosis in tomato (Solanum lycopersicum), fundamentally decoupling microbiome-mediated immunity from pathogen defense. We demonstrated that chemical disturbance...
