The study suggests that integrating microbiome-focused strategies into farming could reduce reliance on chemical pesticides while improving crop health.
Differing Escape Responses of the Marine Bacterium Marinobacter adhaerens in the Presence of Planktonic vs. Surface-Associated Protist Grazers
Researchers found that the marine bacterium Marinobacter adhaerens uses different escape strategies depending on whether predatory protists are free-swimming or surface-attached, suggesting bacteria exploit surface habitats as a refuge from planktonic grazers, with implications for understanding microbial loop dynamics.
Soil protists are more resilient to the combined effect of microplastics and heavy metals than bacterial communities
Researchers compared how soil protists and bacteria respond to combined exposure to microplastics and copper contamination. They found that bacterial communities were immediately affected by copper alone, while protist communities showed a delayed response that only appeared under combined pollution. The study suggests that soil protists are more resilient to mixed microplastic and heavy metal contamination than bacteria, but the combination still disrupts important ecological interactions like predation.
Bacterial and fungal predator – prey interactions modulate soil aggregation
This study examined how predator-prey interactions between bacteria, fungi, and their microbial predators influence soil aggregate formation. While focused on soil ecology, the research is relevant to understanding how microplastic contamination — which alters microbial communities — could indirectly affect soil structure and stability.
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.
PGPR Modulation of Secondary Metabolites in Tomato Infested with Spodoptera litura
Researchers evaluated the effects of two plant growth-promoting rhizobacteria strains (Bacillus endophyticus and Pseudomonas species) on secondary metabolites in tomatoes infested with the pest Spodoptera litura, investigating whether rhizobacteria can bolster plant defenses against insect attack under climate-change conditions. The study demonstrated that PGPR inoculation modulated the production of defensive secondary metabolites in infested tomato plants.
Long-term adaptation study of bacterial isolates of plant growth-promoting bacteria in heat-stressed conditions
Researchers examined whether plant growth-promoting bacteria can adaptively respond to heat stress, finding that bacteria under periodic stress consistently outperformed those under non-periodic stress across multiple growth-promoting traits, with two novel Paenibacillus alvei strains showing the strongest adaptive capacity.
Asymmetric succession in soil microbial communities enhances the competitive advantage of invasive alien plants
Researchers found that invasive plant species gain a competitive edge by recruiting beneficial soil microbes from surrounding native soil, creating an "asymmetric" shift where invasive plants build supportive microbial communities faster than native plants can. This biological feedback loop helps explain why invasive plants spread so successfully and points to new strategies for controlling them.
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.
