ClearThe effects of multifactorial stress combination on rice and maize
Researchers studied how combinations of three or more simultaneous low-level stresses, termed multifactorial stress combination, affect commercial rice and maize crops. They found that even when individual stresses like salinity, heat, herbicide exposure, nutrient deficiency, and heavy metal contamination were each too mild to cause harm alone, their combination significantly reduced plant growth and biomass. The study reveals substantial genetic variability in crop responses to these combined stressors, suggesting some varieties may be more resilient than others.
The effects of multifactorial stress combination on rice and maize
This review examines how plants cope with multiple simultaneous environmental stresses — including drought, heat, flooding, and pollutants like microplastics — finding that combined stressors often cause more harm than individual stresses acting alone.

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.
Abiotic and Biotic Stress Cascades in the Era of Climate Change Pose a Challenge to Genetic Improvements in Plants

Toxicity effects of nanoplastics on soybean (Glycine max L.): Mechanisms and transcriptomic analysis
Researchers exposed soybean plants to polystyrene nanoplastics and observed inhibited stem and root growth, increased oxidative stress, and disrupted photosynthesis. Transcriptomic analysis revealed that nanoplastics altered the expression of genes involved in plant stress responses, hormone signaling, and metabolic pathways. The study suggests that nanoplastic contamination in agricultural soils could negatively affect crop growth and yield at the molecular level.
Current methods and future needs for visible and non-visible detection of plant stress responses
This review examines current and emerging methods for detecting plant stress responses, from molecular-level techniques like genomics and metabolomics to whole-plant remote sensing approaches. Researchers highlight that climate change is creating more complex combinations of stresses that no single detection technology can fully capture. The study calls for integrative multi-omic approaches that connect cellular changes to visible plant-level symptoms for more effective agricultural stress management.
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.

Researchers used transcriptomic analysis to characterize physiological and ecological response characteristics of an aquatic organism exposed to microplastic stress, identifying gene expression changes in pathways related to immune function, oxidative stress, and energy metabolism.
Number of simultaneously acting global change factors affects composition, diversity and productivity of grassland plant communities
Researchers exposed grassland plant communities to increasing numbers of simultaneous global change stressors — such as warming, pollution, and nutrient enrichment — finding that multiple combined stressors reduced plant species diversity even when no single stressor alone had that effect. This highlights that studying environmental threats in isolation can underestimate their true ecological damage.
Phenotypic and transcriptomic shifts in roots and leaves of rice under the joint stress from microplastic and arsenic
This study examined how rice plants respond when exposed to both microplastics and heavy metal cadmium at the same time. Researchers found that the combination caused distinct changes in root and leaf gene expression and growth patterns compared to either pollutant alone. The findings suggest that microplastics may alter how plants take up and respond to heavy metals, potentially affecting crop safety.
Mitigation of microplastic toxicity in soybean by synthetic bacterial community and arbuscular mycorrhizal fungi interaction: Altering carbohydrate metabolism, hormonal transduction, and genes associated with lipid and protein metabolism
Researchers found that inoculating soybean plants with a combination of mycorrhizal fungi and beneficial bacteria helped protect them from microplastic-induced stress, improving biomass, seed quality, antioxidant defenses, and hormone balance. The study suggests that soil microbe communities could be harnessed as a sustainable strategy to help crops cope with growing microplastic contamination in agricultural soils.

A transcriptomics study examined how the plant growth-promoting bacterium VY-1 alleviates combined stress from microplastics and heavy metals in sorghum grown in hydroponic conditions. Inoculation with VY-1 improved biomass and reduced heavy metal accumulation in sorghum, with gene expression analysis revealing the underlying protective mechanisms.
From single to combined stressors: Nanoplastic-ciprofloxacin synergy amplifies oxidative damage and metabolic dysregulation in Glycine max seedlings
When soybean seedlings were exposed to both nanoplastics and the antibiotic ciprofloxacin together, the combined stress was significantly worse than either pollutant alone, stunting growth and disrupting key metabolic processes in the leaves. The nanoplastics reduced root growth and plant size, while the antibiotic primarily damaged leaf function, and together they overwhelmed the plants' antioxidant defenses. This matters for food safety because soybeans are a major crop, and agricultural environments increasingly contain both nanoplastics and antibiotic residues.
Deciphering Pesticide Stress Responses in Rice Through Integrated Multi-Omic Assessment
This review synthesizes research on how pesticide exposure affects rice plants at the molecular level, drawing on transcriptomic, proteomic, and metabolomic studies. Researchers found that pesticides trigger detoxification enzymes, alter antioxidant defenses, and reprogram metabolic pathways in rice. The study highlights how integrating multiple omics approaches can provide a more complete picture of pesticide stress responses in crops.
Single and combined exposure of broad bean (Vicia faba) to PFOS and environmental microplastics: Effect at the morphological, metabolomics and PFOS uptake levels
Researchers grew broad beans in soil contaminated with microplastics and the industrial chemical PFOS, both alone and in combination, for 28 days. While each contaminant individually reduced shoot growth, their combined presence unexpectedly increased biomass, and microplastics enhanced PFOS uptake into plant tissues by up to several fold. Metabolomic analysis revealed significant biochemical disruptions including oxidative stress and altered fatty acid and isoprenoid pathways, particularly under combined exposure.
Polyvinyl chloride microplastics and drought co-exposure alter rice growth by affecting metabolomics and proteomics
Researchers investigated how PVC microplastics combined with drought stress affect rice growth using advanced protein and metabolite analysis. They found that both stressors individually harmed rice development, but together they caused even greater damage to plant metabolism and growth. The study reveals that microplastic contamination in agricultural soils may worsen the effects of drought on crop production.

A Spatially‐Resolved Framework Reveals Contrasting Root and Leaf Strategies to Nanoplastic‐Arsenic Stress in Rice
This study used a new statistical framework to show that rice roots and leaves respond very differently when exposed to both nanoplastics and arsenic simultaneously: roots mount a straightforward additive defense, while leaves show complex antagonistic molecular interactions centred on iron storage. The finding is important for food safety because it reveals that standard toxicity tests on individual stressors may underestimate the risks posed by contaminant mixtures in food crops.
