|a Antibiotics and microplastics (MPs) are two new types of contaminants that are widely existent in agricultural systems. MPs could act as carriers of antibiotics, and affect the bioavailability and degradation of antibiotics, causing a combined effect on plant growth. The aim of the present experiment was to explore the effects of the treatments of oxytetracycline (OTC, 100 mg kg-1) alone and in combination with polyethylene microplastics (PE-MPs, 0.1 %, 1 %, 3 %) on P. ternata phenotypic parameters, photosynthetic system, reactive oxygen species (ROS), secondary metabolism, ascorbate-glutathione (AsA-GSH) cycle, and metabolomics. Results demonstrated that exposure to OTC alone reduced P. ternata fresh weight by causing oxidative damage, reducing photosynthetic pigment and secondary metabolite contents. OTC + MP0.1 group alleviated OTC stress to P. ternata by increasing photosynthetic pigment contents and antioxidant enzyme activities. OTC + MP3 group significantly reduced plant height of P. ternata. In addition, metabolomics analysis showed that OTC treatment interfered with pantothenate and CoA biosynthesis. The OTC + MP0.1 group activated pantothenate and CoA biosynthesis and glutathione metabolism. The significance of this study lies in clarifying the effects of OTC on medicinal plants and whether its influence mechanism is regulated by the concentration of MPs
