Integrated physiological, metabolomic, and transcriptomic responses of maize (Zea mays) and soybean (Glycine max) to nanoplastic-induced stress
Researchers exposed maize and soybean crops to polyethylene and polypropylene nanoplastics in soil and found that high concentrations suppressed plant growth and caused oxidative stress in both species. The nanoplastics accumulated in plant roots and disrupted normal gene activity and metabolism, with soybeans being more sensitive than maize. These findings raise concerns about food crop quality and safety as nanoplastic contamination of agricultural soil increases.

Foliar uptake and leaf-to-root translocation of nanoplastics with different coating charge in maize plants
Researchers showed that nanoplastics can enter maize plants not just through roots but also through leaves, and then travel down to the roots through the plant's internal transport system. Positively charged nanoplastics stuck to leaf surfaces more readily but also caused more damage to photosynthesis and triggered stronger stress responses in the plants. This finding is important because it reveals an additional pathway for nanoplastic contamination of food crops through airborne particles landing on leaves.
