Researchers used an integrated multi-omics approach to study how rye seedlings respond to the combined stress of polystyrene nanoplastics and freeze-thaw cycles.

Freeze–Thaw Cycles Accelerate Plastic Pollution Invasion in Agriculture: Trojan Horse Effect of Microplastic–Plasticizer Contamination Revealed in Rye via Computational Chemistry and Multiomics
Researchers found that climate change-related freeze-thaw cycles significantly worsen the combined toxicity of the plasticizer DEP and microplastics in rye plants. Freeze-thaw conditions increased microplastic uptake into plants by altering particle surface charge, while DEP bound to key plant proteins and inhibited photosynthesis. The study reveals that microplastics simultaneously acted as carriers for the plasticizer while reshaping root microbiomes to favor pollutant-degrading bacteria.

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.

Using hydroponic rye as a model, researchers showed that freeze-thaw cycles dramatically increased diethyl phthalate uptake into plants in the presence of microplastics, with the plasticizer boosting microplastic surface charge and facilitating plant entry. Transcriptomic and computational analyses revealed disruption of gene networks governing growth and stress response.
Multi‐Omics Insights Into Phenylpropanoid and Lipid Barrier Biosynthesis in Maize Roots Under Salt and Microplastic Stresses
Researchers used transcriptomic and metabolomic analyses to investigate how polystyrene microplastics and salt stress — individually and in combination — affect phenylpropanoid and lipid barrier biosynthesis in maize seedling roots, finding that combined stresses alter molecular defence pathways in ways distinct from either stressor alone.
Molecular Trojan Effect of Microplastic Diethyl Phthalate Drives Multiscale Stress Vortex through Interfacial Engineering in Cold Agroecosystems during Freeze–Thaw Cycles
In a 120-day full-lifecycle soil cultivation experiment, researchers combined microplastic diethyl phthalate with freeze-thaw cycles to simulate cold agroecosystem conditions, and used molecular dynamics and multi-omics to characterize the resulting plant and soil stress. The plastic additive caused compounding oxidative and hormonal stress in plants that was amplified under freeze-thaw conditions, revealing a novel "Trojan effect" in cold-climate agricultural soils.
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.
Dynamics of accumulation and multilevel biological effects of various alkyl chain phthalates and microplastics in rye: New insights into individual, physiological, and molecular perspectives
Researchers studied the combined toxicity of three phthalate esters with different alkyl chain lengths and polystyrene microplastics on rye plants, finding that MP presence amplified the phytotoxicity of longer-chain phthalates. The results demonstrate that microplastics can act as carriers that enhance the uptake and toxicity of co-occurring chemical contaminants in crops.

Researchers investigated how nanoplastics and flame retardants interact when co-transported through agricultural irrigation water, using rye as a model crop. The study found that nanoplastics formed stable complexes with flame retardants via van der Waals forces, which accumulated in roots, translocated to seeds, caused severe oxidative damage, and reduced photosynthesis by nearly 65% through synergistic toxic effects.

Carrier effects of microplastics in a hydroponic system: Amplifying diethyl phthalate toxicity and endophytic dysbiosis in Rye (Secale cereale L.) with implications for aquatic ecosystems
Researchers found that polystyrene microplastics and diethyl phthalate (a common plasticizer) interact synergistically to cause severe toxicity in hydroponically grown rye, far exceeding the damage from either pollutant alone.
