ClearResponse of soybean (Glycine max L.) seedlings to polystyrene nanoplastics: Physiological, biochemical, and molecular perspectives
Researchers examined the effects of polystyrene nanoplastics on soybean seedlings in a hydroponic experiment and confirmed that the nanoparticles were taken up by plant roots. The study found that nanoplastic exposure negatively affected growth, increased mineral content in roots and leaves, caused oxidative stress, and altered gene expression related to stress response and hormone signaling pathways.

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.

The Oryza sativa transcriptome responds spatiotemporally to polystyrene nanoplastic stress
Researchers profiled the full transcriptome of rice roots and leaves at multiple time points during polystyrene nanoplastic exposure, finding that nanoplastics suppress photosynthesis and sugar metabolism while activating plant defense pathways — with effects differing between organs and time points in ways that suggest indirect harm via disruption of plant-microbe interactions.
Ecotoxicity and genotoxicity of polystyrene microplastics on higher plant Vicia faba
Researchers exposed fava bean root tips to polystyrene microplastics and nanoplastics and found reduced biomass, increased oxidative stress, and genetic damage in the plant cells. The smaller nanoplastic particles caused more severe effects than the larger microplastics. The study suggests that plastic particle contamination in soil may threaten plant health at the cellular and genetic level.
Discrepancy of Growth Toxicity of Polystyrene Nanoplastics on Soybean (Glycine max) and Mung Bean (Vigna radiata)
Researchers compared how polystyrene nanoplastics affect soybean and mung bean plants grown in water and found that both crops suffered root growth suppression, but through different biological pathways. Soybeans showed more oxidative stress at lower doses, while mung beans were more resilient and only showed significant damage at higher concentrations. The study reveals that different crop species can vary widely in their vulnerability to nanoplastic contamination.
