Microplastics reshape rhizosphere microbial communities and nutrient cycling in tomato agroecosystems
Microplastics (MPs) are emerging soil contaminants increasingly recognized for their capacity to alter agroecosystem functioning; however, their impacts on horticultural crops and rhizosphere microbial processes remain insufficiently understood. Here, we examined the impacts of MPs, polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC), on rhizosphere soil physicochemical properties, bacterial community structure, and functional genes associated with carbon (C), nitrogen (N), and phosphorus (P) cycling in tomato (Solanum lycopersicum L.), a major horticultural crop cultivated worldwide.
