Summary: The microbiota in soil plays a crucial role in inhibiting plant pathogens. However, the relationship between soil particles and local microbial communities has not been fully confirmed. This study examined the differences in microbial communities between suppressive and conducive soils using soil particle-size fractions. The results showed notable differences in composition, traits, and physiochemical parameters between the two soil types. The taxonomic composition of microbial communities also varied significantly. Structural equation modeling revealed complex associations between soil particles, physiochemical parameters, microbial communities, and soil enzyme activities, which influenced soil suppressiveness. These findings highlight the importance of resident microbial communities in specific soil particles for the development of soil suppressiveness.

Summary: This study highlights the importance of utilizing phyllospheric microbes as change-agents to engineer microbial communities for inhibiting fungal pathogen progression in rice crops. The root-shoot linkages play a critical role in the effective biocontrol of indigenous microbes, applied as soil drench or foliar agents. Different microbial inoculation methods show significant effects on chlorophyll concentrations, enzyme activities, and gene abundances, demonstrating the potential for environmentally friendly disease management strategies.

Summary: This study aims to understand the composition and assembly processes of microbial communities in the shallow subsurface of terrestrial ecosystems. It reveals that geological material characteristics and vertical water movement play important roles in shaping these microbial communities. The interactions between bacteria and eukaryotes are mostly positive, indicating potential cooperative or mutualistic associations.

Summary: This paper discusses the estimation of the dependence structure of a multidimensional response variable in the presence of a multivariate covariate. It focuses on the parametric estimation of the copula function using the maximum pseudo-likelihood method, and proves that the estimator based on residuals has the same asymptotic distribution as the estimator based on unobserved errors under certain regularity assumptions. However, a Monte Carlo simulation study shows that the maximum pseudo-likelihood estimator based on residuals may perform poorly when the regularity assumptions are not satisfied.

Summary: The importance and potential of utilizing microbes as bioindicators in water quality monitoring are discussed in this review. Molecular methods have revealed microbial diversity and new metabolic pathways, which can improve our understanding of environmental processes, serving as a solid foundation for novel monitoring programs. Microbial community dynamics are highlighted as a missing link essential for comprehending rapid changes in aquatic ecosystem structure and function, suggesting they should be addressed in future environmental monitoring of freshwater ecosystems.

Summary: The study on common scab of potatoes revealed the influence of plant-microbe-soil interactions on nitrogen, calcium, phosphorus and other nutrient contents affecting susceptibility to the disease. The diversity of bacteria was found to be positively correlated with disease severity, indicating interactions between pathogen populations and soil communities.

Summary: This study explores the application of antagonistic strains to control common scab of potatoes and demonstrates their impact on soil microbial communities and host plant nutrition. One isolate shows significant reduction in the severity of common scab, while inoculation with these isolates leads to changes in host plant nutrition.

Summary: This study compared the bacterial communities associated with seeds of seven weed species after burial in soil for two years and demonstrated the relationships between these changes and seed properties as well as attractiveness for a seed predator. The results showed that seed microbiomes remained specific after burial and contained taxa characteristic for both plant endophytes and insect guts. Changes in seed consumption were partially explained by bacterial communities and seed properties.

Summary: In Mediterranean ecosystems, projected rainfall reduction may alter plant-soil interactions, particularly litter decomposition and home field advantage. This study found that amplified drought conditions led to changes in litter quality and metabolomes, resulting in a slowdown of litter decomposition and loss of home field advantage in Mediterranean forests.
