Summary: Modern agriculture relies heavily on synthetic fertilizers, but nanofertilizers provide an innovative, efficient, and eco-friendly alternative. They release nutrients slowly to support plant growth and conserve beneficial microbiome diversity, although there are still challenges related to production, transportation, and dosage sensitivity.

Summary: This research investigates the mechanisms through which biofertilizers improve soil properties and stimulate plant growth. The study utilizes a bacterial agent and metagenomic technology to explore microbial modulation and soil nutrient turnover. The results show that stimulated soil microbes contribute to enhanced nutrient transformation, leading to improved plant growth. The application of the bacterial agent also affects key genes involved in nitrogen cycling and the composition of the soil microbial community. Furthermore, the study finds that the soil microbial community has genes encoding traits that promote plant growth, highlighting the potential of biofertilizers to improve agricultural practices.

Summary: Legume-based intercropping, specifically rotational strip peanut/cotton intercropping, significantly increases the seed cotton yield and net economic returns without affecting the peanut pods yield. The physiological data indicate that intercropping enhances the leaf net photosynthetic rate, total biomass, and total nitrogen accumulation in peanut pods and cotton buds. Intercropping also increases the total protein and oleic acid contents in peanut kernels. Metabolomics and soil microbial community analysis reveal that intercropping influences the plant metabolic pathways and soil microbial composition and functionality. However, the beneficial effects of intercropping are partially counteracted by the introduction of a solid root barrier.

Summary: The study found that plants are affected by the legacy effects of drought on the rhizosphere microbiome. This drought legacy was propagated and persisted throughout nine weeks of plant growth, independent of prevailing water stress. Drought-impacted rhizospheres had larger populations of desiccation-tolerant and putatively endophytic taxa with established plant growth promoting capabilities.

Summary: The interactions between rhizosphere microorganisms and pioneer plants are crucial for ecological restoration after disturbance. Different pioneer species influence the composition of rhizosphere microbial communities, with bacteria being more sensitive to environmental changes than fungi. Plant traits, rather than species composition, play a key role in shaping the microbial communities in the soil.

Summary: This study analyzed the effects of different agricultural management practices on soil microbial communities, finding that cover crops and residue management had impacts on these communities. Radish-based cover crops were particularly beneficial for microbial abundance and richness, but detrimental for fungal evenness. Crop residues also modulated the effects of cover crops on bacterial abundance and fungal evenness, as well as microbial taxa.

Summary: The microbial communities in the soil surrounding plant roots (rhizosphere) are distinct from those in the non-rhizosphere soil due to root exudation and symbiosis with plant roots. However, little is known about the seasonal variations in these rhizosphere microbial communities, especially during the dormant season of cool temperate forests.

Summary: The rhizosphere microbiome affects plant traits and plants can modulate the composition of the microbial community. Genetic variation in glucosinolate (GLS) production influences the composition of the rhizosphere microbiome. Microbial inoculation affects GLS production, but does not influence insect damage.

Summary: Soil respiration is the largest carbon flux from terrestrial ecosystems to the atmosphere and partitioning the sources of soil carbon dioxide remains uncertain. Through observations and models, we determined that root + rhizosphere respiration, litter respiration, and soil organic matter-derived microbial respiration accounted for 20.1%, 21.8%, and 62.7% of total soil respiration, respectively. Precipitation was the most important factor influencing the proportions of these components, with higher root- and litter-derived soil CO2 fluxes in tropical forests compared to cold temperate and boreal forests. Accurate partitioning of the sources of soil CO2 flux will provide important insights for global carbon budgets.

Summary: In this study, a long-term field experiment was conducted to compare the microbial community compositions in the rhizosphere soil of invasive common ragweed and two native plants. The bacterial and fungal community compositions differed significantly between common ragweed and the two native plants. Invasion by common ragweed selectively accumulated microorganisms that can enhance carbon and nitrogen cycling and the absorption of phosphorus in the rhizosphere environment. Furthermore, microbial inoculants from common ragweed rhizosphere promoted the growth of both common ragweed and Setaria viridis.

Summary: The study showed that enrichment of protective microbiota in the rhizosphere facilitates disease suppression, while disruption of protective rhizobacteria can increase the incidence of disease. Artificial disruption of Gram-positive bacteria in rhizosphere soil resulted in higher occurrence of bacterial wilt in tomatoes. Identification of specific Gram-positive bacteria species in healthy rhizosphere soil contributed to plant immunity activation and enhanced plant disease resistance.

Summary: This study reveals that bacteria emit volatile compounds that can have complex effects on plant growth, with different concentrations of plant growth-inhibiting volatiles (PGIVs) and plant growth-promoting volatiles (PGPVs) having varying impacts at different distances. High concentrations of PGIVs can suppress plant growth and promote immunity, while low concentrations of PGPVs can enhance plant growth.
