ClearPlant growth-promoting bacteria modulate gene expression and induce antioxidant tolerance to alleviate synergistic toxicity from combined microplastic and Cd pollution in sorghum
Scientists found that a beneficial soil bacterium (Bacillus sp. SL-413) can help protect sorghum plants from the combined toxic effects of microplastics and cadmium, a heavy metal. The bacterium boosted plant growth, reduced harmful reactive oxygen species by up to 27%, and reactivated genes that the pollution had shut down. This research points to a nature-based solution for helping food crops survive in microplastic-contaminated soil.

This study offers a potential strategy for maintaining crop productivity in farmland contaminated with both microplastics and heavy metals.
Plant growth-promoting bacteria improve the Cd phytoremediation efficiency of soils contaminated with PE–Cd complex pollution by influencing the rhizosphere microbiome of sorghum
Researchers found that adding beneficial bacteria to soil contaminated with both polyethylene microplastics and the toxic metal cadmium helped sorghum plants grow larger and absorb more cadmium from the soil, improving cleanup potential. This approach matters for food safety because using plants and bacteria to remove combined microplastic-heavy metal pollution from farmland could reduce the amount of these contaminants that enter the food supply.
Effects of combined microplastic and cadmium pollution on sorghum growth, Cd accumulation, and rhizosphere microbial functions
Researchers examined how different types and sizes of microplastics interact with cadmium, a toxic heavy metal, to affect sorghum growth and soil microbes. They found that the combined pollution generally increased plant stress and cadmium uptake, with effects varying by plastic type, particle size, and concentration. The study also revealed that the pollution mixture significantly altered soil bacterial communities and key metabolic pathways involved in nutrient cycling.
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.
Beneficial microbial consortia effectively alleviated plant stress caused by the synergistic toxicity of microplastics and cadmium
Researchers found that combined pollution from microplastics (PVC) and the heavy metal cadmium creates a toxic effect in soil that is worse than either pollutant alone. However, applying beneficial bacteria to contaminated soil helped plants grow better and restored soil nutrients. These findings suggest that probiotic-like bacteria could help repair farmland damaged by microplastic and heavy metal pollution.
Combined effects of heavy metals and microplastics on maize grown in acid and alkaline soils inoculated with plant growth promoting rhizobacteria
Researchers grew maize in soils contaminated with combinations of biodegradable (PLA) and conventional (LDPE) microplastics and heavy metals (Pb, Cd, Zn, Ni) in both acid and alkaline soils, with and without plant growth-promoting bacteria. The combined microplastic-heavy metal contamination reduced growth more than either stressor alone, while bacterial inoculants partially mitigated the damage in alkaline soils.
Diversity and interactions of rhizobacteria determine multinutrient traits in tomato host plants under nitrogen and water disturbances
Researchers investigated how root-associated bacteria help tomato plants maintain nutrient uptake under nitrogen and water stress conditions. They found that microbial diversity and species interactions were key factors in supporting the plant's ability to acquire multiple nutrients simultaneously. While not directly about microplastics, the study advances understanding of soil microbiome dynamics that are relevant to agricultural systems increasingly affected by plastic contamination.
Potential impacts of polyethylene microplastics and heavy metals on Bidens pilosa L. growth: Shifts in root-associated endophyte microbial communities
Researchers found that polyethylene microplastics in soil contaminated with heavy metals significantly stunted plant growth, reducing root length by nearly 49% and increasing harmful reactive oxygen species in plant tissues. The microplastics also shifted the soil's microbial communities toward stress-resistant species, demonstrating how plastic pollution can disrupt the soil ecosystem that supports our food supply.
Microplastics modify plant-arbuscular mycorrhizal fungi systems in a Pb-Zn-contaminated soil
Researchers examined how six types of microplastics affect sweet sorghum growth and soil fungal communities in soil contaminated with lead and zinc. They found that microplastics generally did not inhibit plant growth and in some cases promoted it, but they increased the uptake of heavy metals into plant shoots. The study suggests that microplastics may worsen the risks of heavy metal contamination in agricultural soils by enhancing metal accumulation in crops.

Responses of Sorghum Growth and Rhizosphere–Plastisphere Microbiomes to Cadmium and Polypropylene Microplastic Co-Contamination
Researchers examined how combined cadmium and polypropylene microplastic contamination affects sorghum growth and the bacterial communities in both rhizosphere soil and on the plastic surfaces. They found that co-contamination inhibited sorghum development more severely than either pollutant alone, and the bacterial community on the plastic surface was structurally simpler with lower diversity than in surrounding soil. The study suggests that microplastics in contaminated soils can serve as distinct microbial habitats that differ significantly from the native soil environment.

Assessing the interactive effects of microplastics and acid rain on cadmium toxicity in rice seedlings: Insights from physiological and transcriptomic analyses
Researchers studied how the combination of microplastics, acid rain, and cadmium affects rice seedling growth. They found that at high cadmium concentrations, the presence of microplastics and acid rain actually reduced cadmium's toxic effects by lowering how much of the metal accumulated in the plants. The study provides nuanced evidence that interactions between multiple environmental pollutants can sometimes produce unexpected outcomes, which matters for understanding food safety in contaminated agricultural areas.

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.
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.
