Indole-3-acetic acid and zinc synergistically mitigate positively charged nanoplastic-induced damage in rice
Positively charged 80 nm polystyrene nanoplastics had the greatest impact on rice seedling growth, reducing dry biomass by 41% and root length by 46%, while supplemental zinc and indole-3-acetic acid together significantly alleviated the nanoplastic-induced growth inhibition.
Zinc ions enhance tolerance to nanoplastics stress in rice seedlings: Advancing the development and optimization of traditional zinc fertilizers
Researchers tested whether traditional zinc sulfate fertilizer could help rice seedlings tolerate polystyrene microplastic stress, as an alternative to zinc oxide nanoparticles which carry their own environmental risks. They found that appropriate zinc levels reduced oxidative damage through different mechanisms in shoots versus roots, restoring photosynthesis and development. The findings offer a practical, lower-risk strategy for protecting crops from microplastic contamination in agricultural soils.
Effects of nanoplastics on the growth, transcription, and metabolism of rice (Oryza sativa L.) and synergistic effects in the presence of iron plaque and humic acid
This study examined how nanoplastics affect rice plant growth, finding that the tiny particles were absorbed by roots and entered plant cells. Nanoplastic exposure reduced important enzyme activity and protein levels in roots, disrupting normal plant metabolism. The presence of iron plaque and humic acid in the soil changed how much nanoplastic the plants took up, suggesting that real-world soil conditions play a key role in how crops are affected.

The nano-zinc treatment reduced nanoplastic accumulation in leaves and reversed much of the damage to plant growth and photosynthesis caused by the plastic particles. The study suggests that nano-fertilizers could serve as a tool for managing nanoplastic stress in agricultural crops.

This review examined the use of nano-enabled technologies in rice farming, covering their roles in boosting plant resilience, nutrient uptake, and the efficiency of fertilizers and pesticides. Researchers identified nanoplastic pollution as an emerging concern within agricultural systems alongside more established issues like heavy metal stress. The study calls for standardized environmental risk assessments before these technologies can be widely adopted in food production.

The study suggests nanoparticle-based approaches may help protect crops in microplastic- and heavy metal-contaminated soils.
Molecular mechanisms of toxicity and detoxification in rice (Oryza sativa L.) exposed to polystyrene nanoplastics
Researchers studied how polystyrene nanoplastics affect rice seedlings at the molecular level. They found that nanoplastic exposure significantly reduced root and shoot growth by over 50%, while triggering oxidative stress and activating genes related to both toxicity and defense responses. The study provides new insights into how crop plants respond to nanoplastic contamination at the genetic and physiological level.
Life-long impacts of nanoplastics to rice plant (Oryza sativa L.): Decreased grain yield with perturbed metallome and soil microbiome
Researchers studied how nano-sized PET plastic particles affect rice plants throughout their entire life cycle at concentrations found in real-world environments. They found that nanoplastic exposure reduced grain quality and yield, disrupted mineral nutrient balance, and significantly altered the soil microbial community. The study highlights a potential threat to global food security, since rice is a staple food for billions of people.
Impact of nanoplastics uptake on modulation of plant metabolism and stress responses: a multi-omics perspective on remediation and tolerance mechanisms
Researchers reviewed how nanoplastics accumulate in plant tissues and disrupt metabolism, finding that these particles impair nutrient uptake, trigger reactive oxygen species overproduction, and alter gene and protein expression, while multi-omics approaches are revealing the molecular stress-response networks that plants use to tolerate or remediate nanoplastic contamination.
Mechanistic insight into the intensification of arsenic toxicity to rice (Oryza sativa L.) by nanoplastic: Phytohormone and glutathione metabolism modulation
Nanoplastics at environmentally realistic levels did not harm rice plants on their own, but when combined with arsenic they made arsenic toxicity significantly worse, reducing plant growth by up to 23%. The nanoplastics increased arsenic uptake by disrupting plant hormones and weakening the plant's natural detoxification systems. This is concerning because rice is a staple food for billions of people, and agricultural soils increasingly contain both nanoplastics and heavy metals.
ZnO nanoparticle-based seed priming modulates early growth and enhances physio-biochemical and metabolic profiles of fragrant rice against cadmium toxicity
Researchers studied how zinc oxide nanoparticles applied to rice seeds could help the plants resist cadmium toxicity in contaminated soils. The study found that this seed treatment substantially improved early growth and strengthened the plants' biochemical defenses. These findings suggest a potential strategy for growing crops more safely in soils contaminated with heavy metals.
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.

Researchers investigated nanoplastic stress responses and mitigation strategies in two rice cultivars through biochemical, cytological, physiological, and transcriptome analyses, testing whether molybdenum oxide nanoparticles could alleviate toxicity via heteroaggregation with nanoplastics. Results confirmed nMo reduced oxidative damage markers and that the wild-derived cultivar S18 maintained better physiological function under combined nMo and nanoplastic treatment than cultivated rice.
Effects of individual and combined polystyrene nanoplastics and phenanthrene on the enzymology, physiology, and transcriptome parameters of rice (Oryza sativa L.)
Researchers conducted a hydroponic experiment to evaluate how polystyrene nanoplastics and phenanthrene, individually and in combination, affect rice plants. The study examined effects on enzyme activity, plant physiology, and gene expression over seven days. Evidence indicates that the combination of nanoplastics with organic pollutants can produce different impacts on crop growth compared to either contaminant alone.
Response of rice (Oryza sativa L.) roots to nanoplastic treatment at seedling stage
Researchers exposed rice seedlings to polystyrene nanoplastics and found that the particles were taken up by the roots, aided by water-transporting proteins in the plant. The nanoplastics triggered oxidative stress, reduced root length, and disrupted carbon metabolism and hormone production in the seedlings. The study raises concerns that nanoplastic contamination in agricultural soils could affect crop growth and potentially enter the human food supply through rice consumption.
