The study found that while both stresses reduced photosynthetic performance, chilling exposure actually improved the plant's tolerance to salt stress by helping maintain chloroplast structure and stomatal function.
Synergistic Uptake of Nanoplastics and Sodium Chloride in Tall Fescue Roots Mediated by Cell Wall Architecture
Researchers found that combining nanoplastic exposure with salt stress in tall fescue grass produced synergistic harmful effects far exceeding those of either stressor alone, reducing shoot length by 93% and root length by 79%. Charge-mediated interactions between nanoplastics and sodium ions enhanced the uptake of both contaminants into plant tissues. Nanoplastics altered genes related to cell wall structure and membrane permeability, compromising the plant's ability to tolerate salt stress in saline-alkali soils.
Effects of Exogenous Isosteviol on the Physiological Characteristics of Brassica napus Seedlings under Salt Stress
This study tested how a plant compound called isosteviol helps rapeseed plants cope with salt stress, finding it can boost growth and reduce damage from reactive oxygen species. While not about microplastics, the research is relevant because microplastic contamination in soil can worsen salt stress and oxidative damage in crops. Understanding how plants defend against environmental stress may help develop more resilient crops for contaminated farmland.
Polystyrene Nanoplastics Impair Transcriptional Resilience to Salt Stress in Rice
Scientists found that tiny plastic particles (nanoplastics) make it much harder for rice plants to recover from salt stress, even after the stress is removed. The plastic particles disrupt the plants' ability to turn the right genes on and off, preventing them from bouncing back to normal growth. This matters because nanoplastics are increasingly found in our food system, and this research suggests they could harm crop resilience and potentially affect the nutritional quality of foods we eat.
Genome-Wide Identification of β-Ketoacyl CoA Synthase Gene Family in Melon (Cucumis melo L.) and Its Expression Analysis in Autotoxicity, Saline-Alkali, and Microplastic Exposure Environments
Researchers identified the gene family responsible for producing long-chain fatty acids in melon plants and studied how these genes respond to microplastic exposure and other stresses. They found that specific genes were activated or suppressed when plants encountered microplastics, saline-alkali conditions, or soil toxins from previous crops. The study provides insights into how food crops defend themselves at the genetic level against environmental contaminants including microplastics.
Analysis of Physio-biochemical responses and expressional profiling of DREB transcription factors for drought stress tolerance in Aegilops tauschii Coss
Researchers studied how the wild wheat relative Aegilops tauschii responds to drought stress at physiological and molecular levels. They found activation of specific transcription factors that help regulate stress tolerance genes. These findings have implications for developing drought-resistant wheat varieties through genetic improvement programs.
Comparative Physiological and Transcriptomics Profiling Provides Integrated Insight into Melatonin Mediated Salt and Copper Stress Tolerance in Selenicereus undatus L.
Researchers studied how the hormone melatonin helps dragon fruit plants tolerate salt and copper stress. When both stressors were combined, plant growth dropped by about 54 percent, but melatonin treatment restored growth by roughly 73 percent. Gene analysis revealed that melatonin activates stress defense pathways and secondary metabolite production, identifying key genes that could be targets for developing more stress-resistant crop varieties.
Growth-Promoting Gold Nanoparticles Decrease Stress Responses in Arabidopsis Seedlings
Researchers found that gold nanoparticles unexpectedly promoted plant growth in Arabidopsis seedlings rather than causing toxicity, resulting in longer roots, more lateral roots, and larger rosettes. Transcriptomic and proteomic analyses revealed that gold nanoparticles downregulated oxidative stress responses while upregulating growth-promoting genes. The study provides insight into how certain engineered nanomaterials can have positive rather than harmful effects on plant biology.

Combined transcriptome and metabolome analysis revealed the toxicity mechanism of individual or combined of microplastic and salt stress on maize
Researchers studied how polystyrene microplastics combined with salt stress affect maize seedlings, finding that the combination reduced plant growth by nearly 74%, far worse than either stressor alone. Gene and metabolite analysis revealed that the combined stress severely disrupted energy production, antioxidant defenses, and hormone signaling in the plants. This is relevant to food security because microplastic-contaminated agricultural soils with high salt levels could dramatically reduce crop yields.

This review explores how arbuscular mycorrhizal fungi, beneficial soil organisms that form partnerships with plant roots, help crops cope with environmental stresses like drought, salinity, and heavy metal contamination. The fungi improve nutrient uptake, water absorption, and antioxidant defenses while triggering beneficial hormonal responses in host plants. The authors note that wider agricultural use of these fungi is limited by challenges in mass production and variability across different crops and soil conditions.
Preliminary Analysis of the Salt-Tolerance Mechanisms of Different Varieties of Dandelion (Taraxacum mongolicum Hand.-Mazz.) Under Salt Stress

It examines transcriptomic and metabolomic changes under salt conditions and is not relevant to microplastics or human health.
