ClearInteracting Effects of Heat and Nanoplastics Affect Wheat (Triticum turgidum L.) Seedling Growth and Physiology
Researchers exposed wheat seedlings to polystyrene nanoplastics under both normal (25°C) and elevated (35°C) temperature conditions to test whether heat stress and nanoplastic exposure interact to worsen plant health. They found that the combination of heat and nanoplastics caused greater oxidative stress and growth impairment than either stressor alone, suggesting that climate change could amplify the agricultural damage caused by nanoplastic pollution. This matters because global warming and plastic pollution are both worsening simultaneously, and crops are caught in the crossfire.
Polystyrene nanoplastics in soil impair drought priming-induced low temperature tolerance in wheat
Researchers investigated how polystyrene nanoplastics in soil affect the cold stress tolerance of drought-primed wheat plants. The study found that nanoplastic contamination impaired the beneficial effects of drought priming on photosynthesis and carbohydrate metabolism, ultimately reducing grain yield, suggesting that nanoplastic pollution may undermine crop resilience strategies.
Interactive impacts of heat stress and microplastics contamination on the growth and biochemical response of wheat (Triticum aestivum) and maize (Zea mays) plants
Researchers investigated how heat stress combined with polyethylene microplastic contamination in soil affects wheat and maize growth. They found that the combination significantly reduced plant height, root length, leaf area, and chlorophyll content more than either stressor alone. The findings highlight that microplastic pollution in agricultural soils could worsen the damage already caused by rising temperatures to food crops.
Response of wheat (Triticum aestivum L. cv.) to the coexistence of micro-/nanoplastics and phthalate esters alters its growth environment
Researchers studied how wheat responds to co-existing stressors of microplastics and another soil contaminant, finding that combined exposure altered plant growth, physiological parameters, and grain quality compared to single-stressor exposures. The results highlight the importance of testing contaminant mixtures in agricultural soils.
Polystyrene nanoplastic contamination mixed with polycyclic aromatic hydrocarbons: Alleviation on gas exchange, water management, chlorophyll fluorescence and antioxidant capacity in wheat
Researchers investigated the combined effects of polystyrene nanoplastics and polycyclic aromatic hydrocarbons on wheat plants, finding that co-contamination disrupted gas exchange, water management, chlorophyll fluorescence, and antioxidant capacity more than either pollutant alone.
[Effects of Microplastics on the Growth, Physiology, and Biochemical Characteristics of Wheat (Triticum aestivum)].
Wheat seedlings were grown in soils spiked with 100 nm and 5 μm polystyrene microplastics, with high concentrations (200 mg/L) significantly inhibiting root and stem elongation, reducing chlorophyll, and altering antioxidant enzyme activity, with smaller nanoplastics showing greater toxicity. The findings demonstrate that microplastic size influences phytotoxicity in a major agricultural crop.
The Effects of Temperature Increase and Nanoplastics on Germination and Early Growth of Crop
Researchers tested how temperature increases combined with polystyrene nanoplastic exposure affect radish seed germination and early root growth under laboratory conditions. They found that 100- and 200-nanometer particles actually increased root growth, while temperature significantly affected germination rates, particularly at the highest nanoplastic concentrations. The study provides early evidence that climate change and nanoplastic pollution may interact in complex ways to affect crop development.
The freeze-thaw cycle exacerbates the ecotoxicity of polystyrene nanoplastics to Secale cereale L. seedlings
Researchers exposed rye seedlings to polystyrene nanoplastics followed by repeated freeze-thaw cycles (simulating cold climate conditions), finding that temperature cycling significantly increased nanoplastic accumulation within plant tissues, damaged chloroplasts, inhibited photosynthesis, and amplified oxidative stress beyond the effects of nanoplastics or freeze-thaw stress alone.
How polystyrene nanoparticles and cadmium affect the growth, physiology, metabolic and ionomic profile of early-stage wheat seedlings individually and in combination
Researchers exposed two wheat cultivars to polystyrene nanoplastics and cadmium individually and in combination, finding the combined exposure caused the greatest oxidative stress, metabolic disruption, and ionomic imbalance, while one cultivar (HS-490) showed consistently better tolerance across all stress conditions.
The joint toxicity of polyethylene microplastic and phenanthrene to wheat seedlings
Researchers studied the individual and combined effects of polyethylene microplastics and the pollutant phenanthrene on wheat seedlings grown in soil. They found that microplastics alone caused dose-dependent reductions in plant growth and damaged the photosynthetic system, while the combination with phenanthrene worsened the damage. The study suggests that the co-occurrence of microplastics and organic pollutants in agricultural soils may create compounding negative effects on crop growth.
Nanotoxicological effects and transcriptome mechanisms of wheat (Triticum aestivum L.) under stress of polystyrene nanoplastics
Researchers studied how polystyrene nanoplastics affect wheat plants at the molecular level using gene expression analysis. They found that nanoplastic exposure disrupted genes involved in photosynthesis, hormone signaling, and stress responses, ultimately reducing plant growth. The study provides new insights into how nanoplastic contamination in agricultural soils could harm crop development at a fundamental biological level.
Influence of soil microplastic contamination and cadmium toxicity on the growth, physiology, and root growth traits of Triticum aestivum L.
Researchers grew wheat plants in soil contaminated with polyethylene microplastics, the toxic heavy metal cadmium, or both, finding that combined exposure caused the worst damage — shrinking root area, reducing gas exchange in leaves, and lowering key growth indicators. These findings raise concerns about crop yields in farmland where plastic pollution and heavy metal contamination overlap, which is increasingly common.
Biological Responses to Climate Change and Nanoplastics Are Altered in Concert: Full-Factor Screening Reveals Effects of Multiple Stressors on Primary Producers
Using high-throughput screening of a freshwater green alga, researchers tested how nanoplastics interact with multiple climate change stressors (temperature, CO2, pH, UV), finding that nanoplastics combined with warming or UV caused greater harm than either alone, and that climate change will likely amplify nanoplastic toxicity.
Polystyrene nanoplastics distinctly impact cadmium uptake and toxicity in Arabidopsis thaliana
In a study using the model plant Arabidopsis, polystyrene nanoplastics increased the uptake and accumulation of the toxic heavy metal cadmium in plant roots. The combined stress of nanoplastics and cadmium caused worse oxidative damage and growth problems than either pollutant alone. This is concerning because it means microplastics in agricultural soil could help toxic metals get into crops more easily, potentially increasing human exposure through food.
The combined toxicity of polystyrene microplastic and arsenate: From the view of biochemical process in wheat seedlings (Triticum aestivum L.)
Researchers found that when wheat seedlings were exposed to both arsenic and polystyrene microplastics together, the microplastics reduced arsenic uptake in roots but dramatically increased arsenic transport to the above-ground parts of the plant — by up to 1,000%. This combined exposure caused more oxidative stress and damage to the plants' photosynthetic systems than arsenic alone. The findings suggest that microplastics in contaminated soil could increase how much toxic metal ends up in the edible parts of crops.
Integrated physiological, metabolomic, and transcriptomic responses of maize (Zea mays) and soybean (Glycine max) to nanoplastic-induced stress
Researchers exposed maize and soybean crops to polyethylene and polypropylene nanoplastics in soil and found that high concentrations suppressed plant growth and caused oxidative stress in both species. The nanoplastics accumulated in plant roots and disrupted normal gene activity and metabolism, with soybeans being more sensitive than maize. These findings raise concerns about food crop quality and safety as nanoplastic contamination of agricultural soil increases.
Microplastics reduce the wheat (Triticum aestivum L.) net photosynthetic rate through rhizospheric effects
Microplastics were shown to reduce the net photosynthesis and growth of wheat plants, with effects increasing at higher plastic concentrations. This demonstrates that microplastic contamination in agricultural soils poses a direct threat to crop productivity and food security.
Effects of microplastics and salt single or combined stresses on growth and physiological responses of maize seedlings
Researchers studied how microplastics and salt stress, individually and combined, affect the growth of maize seedlings. They found that combined exposure caused more severe damage than either stressor alone, reducing plant biomass, disrupting photosynthesis, and increasing oxidative damage. The findings are relevant to agricultural regions where plastic mulch films break down into microplastics in salt-affected soils, creating compounding stress on crops.
Wheat (Triticum aestivum L.) seedlings performance mainly affected by soil nitrate nitrogen under the stress of polyvinyl chloride microplastics
Researchers evaluated the effects of polyvinyl chloride microplastics on wheat seedling growth and soil properties. They found that microplastics significantly reduced shoot biomass and soil nitrate nitrogen levels, suggesting that disrupted nitrogen availability may be the primary mechanism affecting plant growth. The study indicates that microplastic contamination in agricultural soils could impair crop development by altering soil nutrient dynamics.
Impact of polystyrene nanoplastics (PSNPs) on seed germination and seedling growth of wheat (Triticum aestivum L.)
Researchers exposed wheat seeds and seedlings to polystyrene nanoplastics and found that while germination rates were unaffected, root growth increased significantly compared to controls. However, the nanoplastics were taken up by the roots and transported to the shoots, reducing micronutrient absorption and altering key metabolic pathways related to energy and amino acid production. The findings suggest that nanoplastics can fundamentally change how crop plants grow and process nutrients.
