ClearReprogramming of microbial community in barley root endosphere and rhizosphere soil by polystyrene plastics with different particle sizes
Barley plants grown in polystyrene microplastic- and nanoplastic-contaminated soil showed altered microbial communities in both the root endosphere and rhizosphere, suggesting plastic pollution can reshape plant-associated microbiomes. These shifts could have downstream consequences for plant health and soil nutrient cycling.
Effects of polyethylene microplastics on the microbial community structure of maize rhizosphere soil
Researchers investigated how polyethylene microplastics from agricultural films affect the microbial communities in crop root zones (rhizosphere), finding shifts in bacterial diversity and function. Disrupting soil microbiomes through microplastic contamination could have downstream effects on soil fertility and crop health.
Effects of polystyrene microplastics on the agronomic traits and rhizosphere soil microbial community of highland barley
Researchers investigated how polystyrene microplastics of different sizes and concentrations affect highland barley growth and the microbial communities in surrounding soil. They found that smaller particles reduced grain weight while larger particles decreased spike dimensions, and all microplastic treatments significantly lowered soil bacterial diversity. The study also showed that adding degrading bacteria helped restore microbial community structure closer to normal conditions.

Researchers examined how polystyrene microplastics and a microplastic-degrading synthetic microbiota consortium (MPDSM) affect highland barley grain nutrition and rhizosphere fungal communities, finding the MPDSM achieved up to 19.9% plastic weight reduction. The study demonstrates that microbiome-based remediation can mitigate some of the negative effects of microplastic contamination on crop rhizosphere ecology.

Researchers examined the individual and combined effects of polystyrene microplastics and a synthetic microbiota consortium (MPDSM) designed for plastic degradation on rhizosphere fungal diversity and grain nutritional quality in highland barley. The MPDSM achieved up to 19.9% weight loss in large microplastic particles and modulated rhizosphere fungal communities, suggesting microbial consortia can partially mitigate crop impacts from microplastic contamination.

Researchers investigated the effects of polystyrene microplastics and a synthetic microbiota consortium (MPDSM) designed for plastic degradation on rhizosphere fungal communities and grain nutritional quality in highland barley. The MPDSM significantly enhanced microplastic degradation and modulated rhizosphere fungal diversity and metabolic function compared to microplastic-only treatments.
Synthetic microbiota for microplastic degradation modulates rhizosphere fungal diversity and metabolic function in highland barley
Researchers examined how a synthetic microbiota consortium (MPDSM) designed for microplastic degradation affects rhizosphere fungal diversity and nutritional quality in highland barley grown in polystyrene-contaminated soil. The MPDSM achieved up to 19.9% weight loss in large microplastic particles and significantly modulated rhizosphere fungal metabolic function, suggesting microbiome-based remediation can partly offset crop quality impacts.
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.
Impact of Nanoplastic Contamination on Rhizosphere Microbiome and Plant Phenotype
This study examined how nanoplastic contamination affects the rhizosphere microbiome (soil bacteria around plant roots) and plant growth. Nanoplastic exposure altered soil microbial communities and reduced plant growth, suggesting these tiny plastic particles could disrupt the soil ecosystems that support food production.

Researchers found that microplastic particles altered wheat rhizosphere soil microbial community composition and function, with different polymer types inducing distinct shifts in bacterial diversity and nutrient cycling processes.
Microplastics contamination in soil affects growth and root nodulation of fenugreek (Trigonella foenum‐graecum L.) and 16 s rRNA sequencing of rhizosphere soil
Researchers found that low-density polyethylene (LDPE) microplastic contamination in field soil negatively affected fenugreek plant growth, root nodulation, and rhizosphere microbial community structure, raising concerns about agricultural soil health.
Agri-plastics in soils drive changes in the rhizosphere bacterial community and plant transcriptome in Arabidopsis
Researchers grew Arabidopsis thaliana in soils mixed with plastic film residues (≥5 mm at 5% w/w) and examined rhizosphere bacterial communities and plant gene expression. Plastic residues significantly altered rhizobacterial composition without affecting plant growth or flowering, suggesting soil microbiome disruption may precede visible plant effects.
Plant pathogenesis: Toward multidimensional understanding of the microbiome
This review explores how the full community of microorganisms on a plant, not just single pathogens, contributes to plant disease. The authors introduce the concept of a 'pathobiome,' the disease-promoting portion of a plant's microbiome that can be influenced by environmental stressors. While not directly about microplastics, the findings are relevant because soil microplastic contamination can alter plant-associated microbial communities in ways that may promote crop diseases.

Root traits and rhizosphere responses as emerging bioindicators of microplastic pollution in agricultural soils: A review
This review examines how microplastic pollution in agricultural soils disrupts root growth, nutrient uptake, and the beneficial interactions between plant roots and soil microbes. Researchers found that microplastics can alter root exudation patterns, change soil structure, and shift microbial communities around roots in ways that may impair crop productivity. The study proposes that root traits and rhizosphere responses could serve as early warning indicators of microplastic contamination in farmland.
