Summary: This study investigates the effect of Rhizophagus irregularis on the expression of plasma membrane aquaporin isoforms in maize leaves under severe drought conditions. The findings show that the regulation of aquaporins by mycorrhiza is dependent on leaf position and is closely related to photosynthesis and stomatal response to drought. The results suggest that mycorrhiza protects the leaves from drought effects by preventing the down-regulation of aquaporins, leading to improved stomatal conductance and faster restoration of photosynthetic capability.

Summary: In the arbuscular mycorrhizal (AM) symbiosis between fungi and their host plants, signals are exchanged at all stages. This study investigates the role of ethylene and cytokinins as interkingdom signals in AM fungi. The findings suggest that AM fungi can respond to a range of phytohormones and that these compounds have multiple functions in the rhizosphere beyond their known roles as plant developmental regulators. The study also sheds new light on the possible perception mechanisms in AM fungi.

Summary: The nature of plant-fungi interaction at early stages of arbuscular mycorrhiza (AM) development is still unclear. In this study, we investigated the changes in the metabolic profile of Medicago lupulina roots during AM symbiosis with Rhizophagus irregularis. The results showed that the root metabolites differed from those in leaves, with accumulation of compounds supporting the growth of mycorrhizal fungus. The intensity of AM development had a greater impact on the root metabolite profile than the host plant's development.

Summary: Leaf nitrogen (N) and phosphorus (P) are important functional traits in plants that affect biogeochemical cycles. Mycorrhiza, as a widely observed plant-fungus mutualistic symbiosis, plays a vital role in regulating plant growth. Different types of mycorrhiza have various ecological functions in nature. Drought stress negatively affects N and P concentrations in arbuscular mycorrhizal (AM) plants, but positively affects the N:P ratio. In contrast, drought stress significantly increases N and the N:P ratio of ectomycorrhizal (ECM) plants but decreases P concentrations. Short-term drought (<30 d) reduces more N and P in AM plants than long-term drought. The effects of N and P on drought stress also vary with different planting conditions and functional groups between AM and ECM plants.

Summary: The symbiotic relationship between plants and fungi undergoes changes across an urban gradient, with plant communities playing a crucial role in arbuscular mycorrhizal fungal colonization levels. However, non-mycorrhizal fungal colonization increases with urbanization. Additionally, root hair presence increases with urbanization. These patterns are driven by an urban syndrome rather than soil chemistry.

Summary: Nitrogen enrichment has negative effects on biodiversity and ecosystem stability, while arbuscular mycorrhizal (AM) fungi play important roles in ecosystem stability and functioning. This study investigated the ecological impacts of N enrichment on AM fungal communities in a grassland ecosystem. The results showed that AM fungal biomass decreased continuously with increasing N addition levels, while AM fungal diversity remained stable until a threshold of 20 g N m(-2) yr(-1) was reached. Above this threshold, AM fungal diversity dramatically decreased, indicating a potentially unstable state of the AM fungal community.

Summary: Rapid urbanization leads to significant changes in land use and soil quality. Glomalin-related soil protein (GRSP), secreted by arbuscular mycorrhizal fungi (AMF), serves as a sensitive indicator of soil quality. Soil microorganisms and enzymatic activities also play a crucial role in improving soil quality and regulating soil nutrient circulation. However, there is limited data on the interactions between GRSP, microorganisms, and enzymatic activities during urbanization. This study in Nanchang, China, found that urbanization indirectly reduces GRSP content by affecting land-use configurations and soil enzymatic activities.

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: Both PAHs and PTEs from coking industries have negative effects on soil ecosystem stability. This study investigated the response of soil microbial diversity and community composition in a typical coking plant to chronic co-exposure of PAHs and PTEs. Microbial interaction networks were built to reveal co-occurrence patterns. The results showed higher concentrations of PAHs and PTEs inside the coking plant compared to outside, and significant differences in bacterial and fungal community composition. Bacterial and fungal communities were shaped by soil chemical properties, PTEs, and PAHs in the coking plant soils. Additionally, competition was the main strategy in fungal networks, while cooperation dominated in bacterial networks.

Summary: AM fungi play a crucial role in the formation and stabilization of soil organic matter (SOM). Previous studies have focused on the organic compounds produced by AM fungi as binding agents for aggregate formation and SOM storage. However, this overlooks the various biogeochemical processes mediated by AM fungal activities, which drive SOM dynamics. We propose an updated conceptual framework to enhance the understanding of AM fungal role in SOM dynamics.

Summary: By studying soil samples from different slope directions along an elevational gradient in a mountain ecosystem, we found that soil bacterial diversity and microbial functions exhibit distinct elevational patterns, which are consistent across slope directions. The bacterial diversity shows a hump-shaped pattern, while microbial functions exhibit a linear increasing trend. Additionally, the beta diversity pattern of soil bacteria is significantly influenced by elevational distance decay relationships. Soil bacterial diversity patterns are determined by transitions in community assembly processes, whereas microbial functions are mainly influenced by bacterial community composition.

Summary: This study demonstrates the significant role of arbuscular mycorrhizal (AM) fungi in reducing the transport of microplastics from roots to shoots in crops. However, AM symbiosis does not substantially decrease the uptake of microplastics by crops from soil. Nevertheless, mycorrhizal fungi can enhance the resistance of crops to microplastics by transforming their chemical properties, reducing complex formation with crop components, and promoting crop phosphorus nutrition.

Summary: Fungi and bacteria are the dominant groups of soil microbial communities worldwide. They play a crucial role in regulating carbon cycling by controlling the turnover of soil organic matter. This study provides the first quantitative and high-spatial-resolution map of soil fungal proportion across terrestrial ecosystems, revealing striking latitudinal trends where fungal dominance increases in cold and high-latitude environments. The study also found a strong nonlinear response of fungal dominance to environmental factors, such as mean annual temperature and net primary productivity. These findings have important implications for improving predictions of soil organic matter turnover under current and future climate scenarios.
