ClearA 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.
Effects of Microplastics on Endophytes in Different Niches of Chinese Flowering Cabbage (Brassica campestris)
Researchers studied how microplastics of different sizes and concentrations affect the microbial communities living inside Chinese flowering cabbage tissues. They found that microplastic exposure significantly altered the endophytic bacteria in roots and stems, increasing the abundance of potentially harmful bacterial species. The study suggests that microplastic contamination in agricultural soils may compromise plant health by disrupting the beneficial microorganisms that naturally reside within crop tissues.

Bacterial-charged biochar enhances plant growth and mitigates microplastic toxicity by altering microbial communities and soil metabolism
Researchers tested whether adding bacteria and biochar (a charcoal-like material) to microplastic-contaminated paddy soil could help rice plants recover, finding that the combined treatment increased shoot weight by over 100% and dramatically improved nutrient uptake genes. The treatment also enriched beneficial soil microbes and reduced oxidative stress in rice, offering a promising strategy for restoring agricultural soils polluted with microplastics.
In-Depth Insights into the Complex Interplay Between Microbial Diversity, Ecological Functionality, and Soil Health in Rice Agroecosystems
This review paper summarizes existing research on tiny organisms (microbes) that live in rice paddies and how they affect the rice we eat. Scientists found that these microbes play important roles in rice farming - they help break down plant waste, control harmful gases like methane, and can influence whether rice contains dangerous toxins or beneficial nutrients. The research suggests that farmers could manage these microbes better to grow healthier rice while protecting the environment, but more studies are needed to make this practical.
Metarhizium anisopliae Mitigates the Phytotoxicity of Lead and Nanoplastics on Rice by Modifying Physiological, Transcriptomic, Metabolomic Activities, and Soil Microbiome
Researchers found that inoculating rice seeds with the fungus Metarhizium anisopliae reduced the harmful effects of both lead and nanoplastic pollution on rice seedlings. The fungus worked by restricting lead uptake, restoring antioxidant balance, activating protective metabolic pathways, and reshaping the soil bacterial community to favor plant-growth-promoting species.
Response strategies of stem/leaves endophyte communities to nano-plastics regulate growth performance of submerged macrophytes.
Nano-polystyrene exposure changed the composition and activity of endophytic bacterial communities in the stems and leaves of aquatic macrophytes, with some endophyte shifts helping plants maintain growth by modulating stress responses, revealing a microbiome-mediated tolerance mechanism.
