Micro/Nano-plastics (M/NPs) have emerged as a globally concerning pollutant. However, research on the phytotoxicity of M/NPs plant secondary metabolism and underlying molecular mechanisms is still limited. Pepper, widely cultivated vegetable, rich in flavonoids, which are class important metabolites found throughout kingdom with multiple biological functions. In this study, we conducted detailed assessment physiological toxicity Polyethylene Terephthalate microplastics (PET-MPs) growth pepper seedlings. Results showed that PET-MPs significantly inhibited growth, particularly root development. Moreover, exposure resulted burst ROS, causing oxidative damage. KEGG pathways analysis illustrated altered flavonoid biosynthesis phenylpropanoid at both metabolome transcriptome levels. Weighted gene correlation network (WGCNA) identified ten structural genes nine transcription factor play pivotal roles regulating biosynthesis. summary, study elucidates alterations composition, along regulatory governing under pepper. These findings enhance our comprehension MPs pollution provide valuable insights for development sustainable agro-ecosystems food security future.
