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.
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.
Characterizing Microplastic Pollution and Microbial Community Status in Rice Paddy Soils Across Varied Environmental Settings in Songjiang, Shanghai: An Analysis of Morpho-Chemical Characteristics
Researchers characterized microplastic pollution and associated microbial communities in rice paddy soils, finding widespread microplastic contamination that correlated with shifts in soil bacterial diversity. Plastic-associated microbial communities differed from bulk soil communities, suggesting microplastics create distinct microbial niches in agricultural environments.
Early inoculation of an endophyte alters the assembly of bacterial communities across rice plant growth stages
Researchers inoculated rice seedlings with a beneficial core endophytic bacterium and tracked how it affected bacterial communities throughout the plant's growth stages. They found the inoculation significantly altered microbial diversity in roots and stems and influenced bacterial community assembly. The study suggests that early introduction of beneficial microbes could be a useful tool for shaping healthier plant-associated microbial communities in agriculture.
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.
Potential effect of key soil bacterial taxa on the increase of rice yield under milk vetch rotation
A long-term paddy field experiment found that milk vetch rotation enriched key phosphate-solubilizing bacterial taxa including Vicinamibacterales, which correlated positively with soil phosphorus availability and ultimately with increased rice yield.
Bacterial communities in co-cultured fish intestines and rice field soil irrigated with aquaculture wastewater
Bacterial communities in fish intestines and rice field soil were compared in an integrated aquaculture-agriculture system where fields are irrigated with fish farm wastewater. Results showed that fish intestinal bacteria influenced the microbial communities in the irrigated soil. Understanding these interactions is important for managing food safety and ecosystem health in aqua-agriculture systems.
Microplastics shape microbial communities affecting soil organic matter decomposition in paddy soil
Researchers found that microplastics shape soil microbial communities in paddy soils in ways that affect organic matter decomposition, revealing how bacterial succession and carbon cycling are altered by microplastic presence in agricultural systems.
Bioinformatic study of the soil microbiome under different cropping systems
This doctoral thesis compares soil microbial communities across different cropping systems using bioinformatics and next-generation sequencing, identifying how intensive agricultural practices degrade soil biodiversity. Healthy soil microbiomes are critical for crop productivity and may influence how soils respond to emerging pollutants like microplastics.
Effects of the Long-Term Continuous Cropping of Yongfeng Yam on the Bacterial Community and Function in the Rhizospheric Soil
Researchers investigated how long-term continuous cropping of yam over 1 to 20 years affects rhizospheric soil bacterial communities and soil properties. The study found that prolonged monoculture caused soil acidification and shifted bacterial community composition, with decreased diversity in most cases, though fields under 20 years of cultivation showed a recovery in bacterial diversity.
The effect of white grub (Maladera Verticalis) larvae feeding on rhizosphere microbial characterization of aerobic rice (Oryza sativa L.) in Puer City, Yunnan Province, China
Researchers investigated how white grub larvae feeding on rice roots alters the surrounding soil microbial community in the rhizosphere, finding that the pest disrupts the balance of beneficial microorganisms that support plant health. Understanding these changes could help develop more targeted approaches to protect rice crops from this soil-dwelling pest.

Researchers examined interactions between maize roots and soil microbial communities, investigating how root-microbe dynamics influence soil health indicators and crop yield. The study found specific rhizosphere microbial associations that promote nutrient availability and plant productivity.
Linking bacterial and fungal assemblages to soil nutrient cycling within different aggregate sizes in agroecosystem
Researchers investigated how bacterial and fungal microbial assemblages within four different soil aggregate sizes correlate with nutrient cycling in rice fields in Southern China, finding that deterministic processes govern bacteria while stochastic processes govern fungi, and that macroaggregates showed stronger regulation of carbon, nitrogen, and phosphorus cycling by soil properties than microaggregates.

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.
