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.

Identification of microplastic-associated microbial communities from various stages of wastewater treatment and recipient surface waters using MALDI-TOF mass spectrometry
Researchers deployed six polymer types at different stages of wastewater treatment across three Hungarian plants and used MALDI-TOF mass spectrometry to identify the bacteria colonizing microplastic surfaces, finding distinct microbial communities that may act as vectors for antibiotic resistance.
Host species and microplastics differentiate the crop root endophytic antibiotic resistome
Researchers found that crop species and microplastic contamination significantly shape the antibiotic resistance gene profile in plant root endophytes, with microplastics enhancing resistance gene abundance via changes in root-associated microbial communities.
Influence of soil microplastic contamination on maize (Zea mays) development and microbial dynamics
Researchers grew maize (corn) in soil contaminated with varying amounts of microplastics and found that higher microplastic levels disrupted soil bacteria and fungi, caused leaf damage like yellowing and tissue death, and led to elevated heavy metals in plant tissue above safe limits. The results point to serious risks microplastics pose to crop health, soil ecosystems, and food safety.
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.
‘OMICS’ Studies on Rhizosphere-Microorganism Interactions in Soils
This review covers OMICS approaches—genomics, transcriptomics, proteomics, metabolomics—used to study how plant root microbiomes interact with soil in the context of pollutants including microplastics and heavy metals. It highlights how rhizosphere microorganisms mediate phytoremediation and discusses multi-resistance challenges when pharmaceuticals and pesticides co-contaminate soils.
Comparative effect of silver nanoparticles on maize rhizoplane microbiome in initial phaseof plants growth
This is not about microplastics — it is a soil microbiology study examining how five different forms of silver nanoparticles with varying surface properties affect the bacterial and fungal communities in the root zone of maize seedlings.
Metagenome analysis of a soil and marine environment
This metagenomics thesis analyzed microbial communities on marine microplastics and in plant root zones, finding that the biofilm on plastic particles includes bacteria that may be capable of plastic degradation. Identifying the composition and function of these microbial communities could help in the discovery of plastic-degrading microorganisms.
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.
Reprogramming 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.
Effect of microplastics on rhizosphere and arbuscular mycorrhizal fungi of Zea mays
Researchers exposed maize to two types of polyethylene microplastics (0.1% and 0.5% w/w) in glasshouse conditions for seven weeks and measured effects on rhizosphere fungi and arbuscular mycorrhizal fungi. Mycorrhizal root colonization, spore abundance, and fungal diversity were significantly reduced in a concentration-dependent manner, potentially impairing plant nutrient uptake.
Harnessing beneficial microbes to counteract the negative impact of microplastics (raw and aged) on plant health and oxidative balance
Researchers tested whether combined microbial inoculation could mitigate the oxidative stress and growth inhibition caused by aged microplastics in maize. Microbial consortia effectively restored antioxidant defenses and growth by alleviating MP-induced disruptions to proline and MAPK stress pathways.
