Nanoplastic alters soybean microbiome across rhizocompartments level and symbiosis via flavonoid-mediated pathways
Researchers applied polypropylene and polyethylene nanoplastics to soybean growing conditions and found that the particles altered soil chemistry, changed bacterial communities, and unexpectedly accelerated root nodule formation and nitrogen-fixing activity at lower doses. The effects varied by plastic type, with polyethylene nanoplastics having a stronger impact on soil enzyme activity. The study reveals that nanoplastic pollution can reshape the soil microbiome and influence how plants form beneficial partnerships with nitrogen-fixing bacteria.
Toxicological effects and molecular metabolic of polystyrene nanoplastics on soybean (Glycine max L.): Strengthening defense ability by enhancing secondary metabolisms
Researchers exposed soybean seedlings to polystyrene nanoplastics and found that the tiny particles were absorbed by the roots and transported throughout the plant. The nanoplastics caused oxidative stress and slowed growth, though the plants activated defense mechanisms through secondary metabolism. This is concerning because crops that absorb nanoplastics could transfer them to humans through the food supply.
