Polyethylene terephthalate nanoplastics affect potassium accumulation in foxtail millet (Setaria italica) seedlings
Our research indicates that PET nanoplastic treatment induces the expression of genes related to K<sup>+</sup> uptake in foxtail millet through ROS signaling, leading to increased K<sup>+</sup> accumulation in the leaves. This process mitigates the ROS damage caused by PET nanoplastic treatment by increasing the expression and activity of genes encoding antioxidant enzymes. The present research has unveiled the K<sup>+</sup> accumulation-related response mechanism of foxtail millet to PET nanoplastic treatment, contributing significantly to our understanding of both the potassium absorption regulation mechanism in plants and the broader impact of plastic pollution on agricultural crops. This discovery not only highlights the complexity of plant responses to environmental stressors but also underscores the importance of considering such responses when evaluating the ecological and agricultural implications of plastic pollution.
