Microplastics have rice cultivar-dependent impacts on grain yield and quality, and nitrogenous gas losses from paddy, but not on soil properties
A pot experiment with different rice cultivars found that polyethylene microplastics affected grain yield, quality, and nitrogen cycling in a cultivar-dependent manner, indicating that genetic background modulates plant sensitivity to microplastic contamination. The findings have implications for agricultural management in regions where microplastic-contaminated soils are common.
A Spatially‐Resolved Framework Reveals Contrasting Root and Leaf Strategies to Nanoplastic‐Arsenic Stress in Rice
This study used a new statistical framework to show that rice roots and leaves respond very differently when exposed to both nanoplastics and arsenic simultaneously: roots mount a straightforward additive defense, while leaves show complex antagonistic molecular interactions centred on iron storage. The finding is important for food safety because it reveals that standard toxicity tests on individual stressors may underestimate the risks posed by contaminant mixtures in food crops.
The importance of being petioled: leaf traits and resource-use strategies in Nuphar lutea
Researchers examined intraspecific trait variability (ITV) in leaf morphology and petiole characteristics of the floating-leaved macrophyte Nuphar lutea across a hyper-eutrophic shallow lake in central Italy, finding that water depth and sediment properties modulated resource-use strategies, with leaf area and biomass increasing with depth reflecting the construction costs of longer petioles.
Assessing Grain Quality Changes in White and Black Rice under Water Deficit
This paper is not about microplastics; it is an agricultural study comparing grain quality — including phenolic content, antioxidant capacity, and mineral composition — in white and black rice varieties grown under conventional flooding versus alternate wetting and drying irrigation regimes.
Oryza rufipogon and nanoparticles mitigate nanoplastic toxicity by modulating lignin, cell wall thickening, and carbohydrate metabolism
Researchers compared wild rice (Oryza rufipogon) and cultivated rice under nanoplastic stress, finding that wild rice suffered far less growth and chlorophyll loss due to greater lignin deposition, stronger antioxidant defenses, and activation of cell wall-strengthening genes, while adding nano-selenium partially restored growth in both varieties.
Microplastics affect rice (Oryza sativa L.) quality by interfering metabolite accumulation and energy expenditure pathways: A field study
Researchers conducted a field study examining how polystyrene microplastics affect rice grain quality at the molecular level using metabolomic and transcriptomic analysis. They found that microplastic exposure interfered with metabolite accumulation and energy pathways in the rice plants, ultimately reducing grain quality. The study provides real-world evidence that microplastic contamination in agricultural soils can directly compromise the nutritional quality of a major food crop.
Integrated Physiological, Transcriptomic and Metabolomic Analyses of the Response of Rice to Aniline Toxicity
Researchers used physiological, transcriptomic, and metabolomic analyses to study how rice plants respond to aniline, a chemical pollutant derived from plastics and industrial processes. They found that low concentrations slightly promoted growth, but higher levels significantly inhibited rice development and activated stress response pathways. The study provides molecular-level insights into how this common industrial contaminant affects crop plants.

Influence of Water Depth on the Morphology Structure of Seagrass from the Southern of Peninsular Malaysia
This study is not about microplastics; it examines how water depth affects the leaf and root morphology of two seagrass species in Malaysia, finding that nutrient availability and proximity to the mainland influenced plant growth more than depth alone.
Toxicological effects and transcriptome mechanisms of rice (Oryza sativa L.) under stress of quinclorac and polystyrene nanoplastics
Researchers found that combined exposure to polystyrene nanoplastics and the herbicide quinclorac caused greater toxicity to rice than either stressor alone, with transcriptome analysis revealing disrupted pathways in photosynthesis, oxidative stress response, and hormone signaling.
The effects of multifactorial stress combination on rice and maize
Researchers studied how combinations of three or more simultaneous low-level stresses, termed multifactorial stress combination, affect commercial rice and maize crops. They found that even when individual stresses like salinity, heat, herbicide exposure, nutrient deficiency, and heavy metal contamination were each too mild to cause harm alone, their combination significantly reduced plant growth and biomass. The study reveals substantial genetic variability in crop responses to these combined stressors, suggesting some varieties may be more resilient than others.
The effect of soil microplastics on Oryza sativa L. root growth traits under alien plant invasion
Researchers studied how microplastics in soil interact with an invasive weed species to affect rice root growth.
