ClearPolyethylene Microplastic Particles Alter the Nature, Bacterial Community and Metabolite Profile of Reed Rhizosphere Soils
Researchers found that polyethylene microplastic particles alter the bacterial community composition, soil environmental factors, and metabolite profiles of reed rhizosphere soils, with effects increasing at higher microplastic concentrations and showing distinct interactions with reed biomass.
A Comparison of Rice Root Microbial Dynamics in Organic and Conventional Paddy Fields
Researchers compared the root-associated microbial communities of rice plants grown in organic versus conventional paddy fields across different growth stages. They found that organic farming supported more dynamic and diverse microbial communities, including beneficial methane-oxidizing and nitrogen-fixing bacteria at key growth stages. The study suggests that agricultural management practices significantly shape the microbial partners that support rice plant health and nutrient uptake throughout the growing season.
Rhizosphere microbial activities in response to combined effects of drought and microplastic
Researchers studied how combined drought stress and microplastic contamination affect rhizosphere microbial activities, finding that microplastics exacerbated drought-induced suppression of soil enzyme activities and altered microbial community structure around plant roots.
Soil metagenomics reveals the effect of nitrogen on soil microbial communities and nitrogen-cycle functional genes in the rhizosphere of Panax ginseng
Researchers studied how different levels of nitrogen fertilizer affect the soil microbial communities around ginseng roots. They found that moderate nitrogen boosted beneficial microbes and improved ginseng yields, while excessive nitrogen decreased soil pH, reduced microbial diversity, and increased disease-causing organisms. The study highlights the importance of balanced fertilizer use for maintaining healthy soil ecosystems in agricultural settings.
Effects of microplastics on common bean rhizosphere bacterial communities
Researchers studied how polyethylene and biodegradable microplastics affect bacterial communities in the root zone of common beans. Both types of microplastics significantly altered the diversity and composition of rhizosphere bacteria, with biodegradable microplastics inducing more distinctive changes than conventional polyethylene at higher concentrations.
16S rRNA gene amplicon-based metagenomic analysis of bacterial communities in the rhizospheres of selected mangrove species from Mida Creek and Gazi Bay, Kenya
This metagenomic study characterized rhizosphere bacterial communities of four mangrove tree species in Kenya, finding species-specific differences in microbial diversity and community structure that reflect the distinct root chemistry and sediment conditions of each mangrove host.
Influence of different irrigation methods on the alfalfa rhizosphere soil fungal communities in an arid region
Researchers examined how traditional flood irrigation versus drip irrigation methods affect fungal diversity, community structures, and ecological functions in alfalfa rhizosphere soils in the arid Xinjiang region of China, finding that irrigation method significantly shapes soil fungal communities.
Eco-environmental responses of Eichhornia crassipes rhizobacteria community to co-stress of per(poly)fluoroalkyl substances and microplastics
Researchers studied how the combined presence of microplastics and PFAS chemicals affects the bacterial communities living on water hyacinth roots. They found that these pollutants significantly altered the composition and diversity of root-associated bacteria, with different plastic types and chemical combinations producing distinct microbial shifts. The findings suggest that co-contamination by microplastics and PFAS could disrupt the beneficial microbial communities that aquatic plants depend on for healthy growth.
Linking rhizospheric microbiota and metabolite interactions with harvested aboveground carbon and soil carbon of lakeshore reed wetlands in a subtropical region
Researchers studied how soil microorganisms and plant-produced chemicals in wetland reed rhizospheres interact to influence carbon storage in lakeside wetlands. Understanding these relationships helps protect wetlands as important carbon sinks in the face of climate change.
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.
Culturomics and Amplicon-Based Metagenomic Insights into the Bacteria of Soils with High Yield of Oryza sativa L. subsp. Japonica
Researchers used culturomics and amplicon-based metagenomics to characterise bacterial communities in rhizosphere and bulk soils of high-yield Oryza sativa japonica paddy fields, identifying the microorganisms contributing to rice growth adaptability. The combined approach revealed the taxonomic composition and functional potential of the bacterial community in the paddy field agroecosystem.
Effects of microbial cultures on bacterial communities in the roots of Phyllostachys edulis
Researchers investigated the effects of applying endophytic bacterial cultures isolated from Phyllostachys edulis on bacterial communities in bamboo root systems and rhizosphere, as well as on soil chemical properties. Seven root samples were collected from experimental plots treated with a mixed culture of four bacteria, revealing how microbial inoculants reshape root-associated microbial communities.
Impacts of biodegradable microplastics on rhizosphere bacterial communities of Arabidopsis thaliana: Insights into root hair-dependent colonization
Researchers investigated how biodegradable microplastics from PBAT plastic affect the bacterial communities around plant roots, using two genotypes of Arabidopsis with different root hair lengths. They found that longer root hairs promoted greater bacterial colonization and diversity, and that biodegradable microplastics boosted enzyme activity and shifted bacterial community composition in the root zone. The findings suggest that the effects of biodegradable microplastics on soil health depend on plant root characteristics.
Application of Organic Fertilizer Changes the Rhizosphere Microbial Communities of a Gramineous Grass on Qinghai–Tibet Plateau
Researchers examined how organic fertilizer application altered rhizosphere microbial communities in a gramineous grass, finding significant shifts in bacterial diversity and composition that may influence nutrient cycling and soil health in grassland ecosystems.

Reeds (Phragmites australis) modulate the impacts of microplastics on carbon and nitrogen metabolisms in wetland soil
Researchers investigated how polypropylene microplastics at two concentrations differentially affected soil carbon and nitrogen metabolic processes in wetland soils in the presence and absence of reeds (Phragmites australis). They found that the plant-microbe-microplastic interaction produced contrasting effects: in planted soils, microplastics enhanced the reductive citrate cycle and suppressed denitrification gene abundance, while these effects were absent in unplanted soils.
Rhizospheric bacterial communities against microplastics (MPs): Novel ecological strategies based on the niche differentiation
Researchers studied how bacterial communities living around plant roots adapt when exposed to microplastics in soil. They found that rhizosphere bacteria developed distinct survival strategies depending on their ecological niche, with some species thriving while others declined in the presence of plastics. The study reveals that microplastics can reshape the microbial communities that plants depend on for nutrient uptake and disease resistance.

Nitrogen metabolic responses of non-rhizosphere and rhizosphere microbial communities in constructed wetlands under nanoplastics disturbance
Researchers compared how microbial communities in plant root zones versus non-root zones of constructed wetlands respond to nanoplastic contamination. They found that nanoplastics reduced beneficial nitrogen-processing bacteria near roots by nearly 18%, while non-root microbes showed greater adaptability, even using nanoplastics as a carbon source. The findings suggest that constructed wetlands, which are important for water treatment, may have their nitrogen-removal capabilities impaired by nanoplastic pollution.
