ClearAlleviation ofNanoplastic Stress in Rice: Evidencefrom Biochemical, Cytological, Physiological, and Transcriptome Analysis
Researchers used biochemical, cytological, physiological, and transcriptomic analyses to investigate nanoplastic stress in two rice cultivars and the mitigating effect of molybdenum oxide nanoparticles (nMo), finding that nMo heteroaggregates with nanoplastics and reduces oxidative stress markers including H2O2 and MDA by 9-19%. The wild-derived cultivar S18 showed superior cellular protection compared to cultivated MeiXiangZhan, suggesting genetic variation in nanoplastic tolerance.
Alleviation of Nanoplastic Stress in Rice: Evidence from Biochemical, Cytological, Physiological, and Transcriptome Analysis
Researchers studied how MoO3 nanoparticles alleviate nanoplastic stress in two rice cultivars, finding that MoO3 heteroaggregates with nanoplastics, reducing their uptake and mitigating biochemical, cytological, and transcriptomic stress responses in rice seedlings.
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.
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.
Divergent Responses of Rice ( Oryza sativa L.) Cell Wall to Cd Phytotoxicity Affected by Continuous Nanoplastics Stimulation
Researchers exposed rice plants to nanoplastics and cadmium, revealing a dosage-dependent dual effect: low nanoplastic doses immobilized 72% of cadmium in roots, while high doses disrupted cell wall integrity and increased cadmium translocation to shoots by 34%, worsening toxicity.
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.
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.
Divergent Responsesof Rice (Oryzasativa L.) Cell Wall to Cd Phytotoxicity Affectedby Continuous Nanoplastics Stimulation
Researchers found that nanoplastics exert a dosage-dependent dual effect on cadmium toxicity in rice roots: low doses helped sequester cadmium in the cell wall, while high doses disrupted cell wall structure and allowed 34% more cadmium to translocate to shoots.
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.
Photoaging ExacerbatesNanoplastic Phytotoxicity andDifferentially Activates Defense Mechanisms in Wild versus CultivatedMaize
Researchers compared how photoaged polystyrene nanoplastics affect cultivated maize and its wild ancestor, finding that photoaging amplified toxicity, caused greater oxidative damage, and revealed that cultivated maize was more vulnerable than its wild progenitor.
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.
Fe2O3-modified graphene oxide mitigates nanoplastic toxicity via regulating gas exchange, photosynthesis, and antioxidant system in Triticum aestivum
Researchers found that iron oxide-modified graphene oxide nanoparticles can mitigate nanoplastic toxicity in wheat by improving gas exchange, photosynthesis, and antioxidant defense systems, offering a potential nanomaterial-based strategy for protecting crops from plastic pollution.
Multiomics analysis reveals a substantial decrease in nanoplastics uptake and associated impacts by nano zinc oxide in fragrant rice (Oryza sativa L.)
Researchers found that nano zinc oxide (nZnO) particles form aggregates with polystyrene nanoplastics in the root zone of fragrant rice, physically blocking nanoplastic uptake, while transcriptomic and metabolomic analyses revealed that nZnO also restored antioxidant defenses and rescued aroma compound biosynthesis that nanoplastics had disrupted.
Multifunctional Roles and Ecological Implications of Nano-Enabled Technologies in Oryza sativa Production Systems: A Comprehensive Review
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.
Nanoparticle-driven defense in wheat (Triticum aestivum L.): Enhancing antioxidant and rhizosphere responses under arsenic and microplastic stress
Researchers tested whether silicon, silicon dioxide, and silver nanoparticles could protect wheat from combined arsenic and microplastic stress in soil, finding that all three nanoparticle types improved antioxidant activity, reduced oxidative damage, and supported rhizosphere microbial community recovery.
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.
Glutathione treatment suppresses the adverse effects of microplastics in rice
Researchers found that exogenous glutathione application can suppress the adverse effects of microplastics on rice growth, mitigating oxidative stress and protecting yield by bolstering the plant's antioxidant defense system against microplastic-induced damage.

Modulations in protein phosphorylation explain the physiological responses of barley (Hordeum vulgare) to nanoplastics and ZnO nanoparticles
Researchers examined how the co-exposure of barley plants to nanoplastics and zinc oxide nanoparticles affects protein phosphorylation and physiological responses. The study found that the combination of nanomaterials increased oxidative stress and altered hormone levels more than individual exposures, suggesting that interactions between nanoplastics and other nanomaterials in the environment may amplify their effects on plant health.
