Impact of microplastic residues from polyurethane films on crop growth: Unraveling insights through transcriptomics and metabolomics analysis
Residual plastic films from coated fertilizers harmed wheat growth by disrupting energy metabolism in roots, with one type reducing plant height by nearly 25%. However, some bio-based polyester films triggered plant defense responses that offset the damage, suggesting that switching to certain biodegradable alternatives could reduce the microplastic-related risks to crop production and food safety.

Transcriptomics, proteomics, and metabolomics interventions prompt crop improvement against metal(loid) toxicity
This review examines how advanced molecular analysis tools -- transcriptomics, proteomics, and metabolomics -- are helping scientists understand how plants respond to toxic metals in contaminated soil. While focused on metal toxicity rather than microplastics directly, these same tools are being used to study how microplastics interact with heavy metals to create combined threats to crop safety and human health.
Metabolomics revealing the response of rice (Oryza sativa L.) exposed to polystyrene microplastics
Researchers used metabolomics to investigate how polystyrene microplastics affect rice plants through both laboratory and field experiments.
