Summary: This study investigated the response of fungal communities in agricultural soils from ten different provinces in China to varying soil properties and chromium (Cr) concentrations. The results showed that high concentrations of Cr led to significant changes in the composition of fungal communities, with soil properties having a greater impact than Cr concentration. It also identified certain functional groups of fungi, such as mycorrhizal fungi and plant saprotrophs, that were significantly affected by high Cr concentrations. The study provided insights for ecological risk assessment and bioremediation techniques for Cr-contaminated soils.

Summary: Understanding the metabolic diversity in the rhizosphere soil of pecan plantations is crucial for plant protection and forest productivity improvement. This study used untargeted metabolomics and high-throughput sequencing to investigate the differences in metabolic profiles between rhizosphere and bulk soils and the relationship between metabolites and microorganisms in pecan plantations. The findings revealed significant differences in metabolite abundance between rhizosphere and bulk soils, particularly in plant secondary metabolites and lipids. The study also identified specific metabolic pathways and factors influencing the rhizosphere metabolic spectrum, providing new insights into the interactions between pecan trees and microorganisms.

Summary: Foliar fertilization is an effective method to regulate plant nutrition. This study assessed the effects of different foliar fertilizers on the growth, chemical composition, rhizosphere soil properties, and fungal community of Dioscorea opposita. The results showed that foliar fertilizer directly affected plant growth and chemical content. Nutrient elements were the main factors affecting fungal composition, and soil microelements positively influenced soil fungi while soil macroelements negatively influenced them.

Summary: Long-term monocultures of tea and excessive use of chemical fertilizer degrade soil quality. This study explored the effects of Pinus and Chinese fir on soil nutrients and fungal communities in ex-tea plantations that were reforested with pure forest and mixed forest modes. After reforestation, the mixed forest showed increased vegetation index and improved soil organic carbon, total nitrogen, and N:P ratio compared to the pure forest. The fungal communities in the mixed forest exhibited changes in composition, leading to increased symbiotrophs and decreased complex nutrient types. This study highlights the importance of reforestation with a mixed forest to improve degraded soils in ex-tea planting areas.

Summary: Climate change is causing forest lines to shift higher globally, impacting soil biota and carbon sequestration. Analysis of soil biota composition across the forest line ecotone revealed significant differences in fungal and micro-eukaryotic populations. Ectomycorrhizal and saprotrophic fungi dominate below the forest line, while root-associated ascomycetes are more prevalent above it. Ergosterol and soil carbon content strongly correlated with root-associated ascomycetes abundance, suggesting potential implications for carbon turnover and sequestration.

Summary: This study investigated the influence of biochar on soil content, enzymatic activity, and fungal community diversity and structural composition through a soil column leaching simulation experiment. The results showed that biochar increased the pH value and the contents of soil organic matter, total nitrogen, available phosphorus, and available potassium, but reduced the microbial biomass carbon and microbial biomass nitrogen. Biochar also affected enzymatic activity and the diversity and structure of the fungal community. Furthermore, biochar inhibited the growth of harmful pathogens and increased the abundance of beneficial fungi in soil.

Summary: In this study, the fungal communities in different soil compartments (rhizosphere vs. bulk soil) of moso bamboo (Phyllostachys edulis) and its four varieties were compared using high-throughput sequencing technology. The results showed that the fungal alpha diversity was higher in bulk soil than in rhizosphere soil, and it was not affected by bamboo variety. Both soil compartment and bamboo variety explained 31.74% of the variation in fungal community diversity. Soil compartment mainly affected the relative abundance of dominant fungal phylum, while bamboo variety primarily influenced the dominant fungal genus. Network analysis revealed that the fungal network in rhizosphere soil was more complex, stable, and interconnected compared to bulk soil. Our findings highlight the importance of soil compartments and plant species in shaping soil fungal communities.

Summary: A stable arbuscular mycorrhizal fungi (AMF) community is crucial for soil stability and structural improvement in apple orchards. This study reveals the negative correlation between soil properties (organic carbon, pH, and relative abundance of Archaeospora) and replant disease (ARD) severity. Total nitrogen and available phosphorus are identified as the main drivers of AMF communities in perennial apple orchard soil.

Summary: This study investigated the relationship between Pinus massoniana genotype and ectomycorrhizal (ECM) fungal communities by examining ECM fungal communities, soil nutrients, extracellular enzyme activity, and leaf nutrient concentrations in families with different growth levels. The results showed that the high-growth (HG) family had more diverse ECM fungal communities compared to the medium-growth (MG) and low-growth (LG) families. Amphinema was the main contributor to the differences among the families and positively affected the growth of the HG family and the accumulation of soil organic carbon.

Summary: Fungal decomposition of soil organic matter is influenced by soil nitrogen availability, which is in turn impacted by atmospheric nitrogen deposition. Changes in nitrogen inputs have led to shifts in fungal communities, with some showing increased biomass and richness in response to nitrogen deposition while others exhibit reduced oxidative enzyme potential. Fungal communities respond differently to simulated nitrogen deposition based on ambient nitrogen levels, indicating a complex relationship between nitrogen enrichment and fungal community structure and function.

Summary: This study found that soil fungal community composition varies across soil horizons, with higher species richness and diversity in the O horizon. Total organic carbon, total organic nitrogen, alkali-hydrolyzable nitrogen, available potassium, and available phosphorus significantly influence fungal community composition, abundance, and diversity. Precipitation also has a significant effect on fungal community composition.

Summary: This study evaluated the impact of three composting piles on the bacterial and fungal communities of baby-leaf lettuce crops, finding that fungal communities were more influenced by composting phases while bacterial communities were more sensitive to chemical changes. All composts were considered stable and mature, with compost C_C showing higher maturity. Bacterial phyla related to soil-borne pathogen suppression were more abundant in all three composts, but C_A and C_B showed higher suppressiveness against P. irregulare than C_C, likely due to higher abundance of potential suppressive genera such as Aspergillus and Penicillium.
