Nano/microplastics (N/MPs) induce phytotoxicity and represent a significant global threat to terrestrial agricultural ecosystems. However, the defense mechanisms of plants against different-sized N/MPs remain largely unknown. To address this knowledge gap, we investigated interactions between polystyrene (PS) NPs (50 100 nm) PS-MPs (200 500 with taro (Colocasia esculenta). We found that PS particles varying sizes exhibited differential root adsorption penetration, PS-NPs capable penetrating epidermis, whereas were totally excluded. Notably, demonstrated capacity recognize different responded degrees resistance. In reaction more toxic 50 nm PS-NPs, roots mobilized robust mechanism three levels: molecular, compositional, ultrastructural. This was achieved by activating lignin synthesis, carbohydrate metabolism, lipid transport, resulting in doubling lignified region increases cell wall thickness 116%, 56.3%, 22.5% exodermis, cortex, respectively. Consequently, excluded all four outside vascular tissue prevented contamination corms. Our study provides new insights into interaction demonstrates crucial role barriers sustaining food safety.
