Functional Resistance of Microbiome to Differently Charged Nanoplastics in Rhizosphere Hotspots Soil

Journal of Agricultural and Food Chemistry 2026

Summary

Researchers assessed how differently charged nanoplastics affect microbial communities in rhizosphere soil and found that functional hotspot microbes — particularly Actinobacteria — maintained resistance by accelerating nitrogen and phosphorus cycling to compensate for nutrient deficits that would otherwise impair maize growth.

H maintained higher microbial resistance. Functional hotspots microbial species (particularly in Actinobacteria) alleviated NPs toxicity by accelerating N and P cycling to meet the demand for nutrients limiting maize growth. This study provides a mechanistic basis for assessing soil NPs risk with implications for agricultural sustainability and food safety.
