Summary: The study found that varying daytime/nighttime elevated CO2 levels along with the presence of arbuscular mycorrhizal fungi (AMF) significantly increased AMF mycorrhization, soil organic carbon, total nitrogen, and various forms of the glomalin-related soil protein (GRSP). Under daytime eCO(2), soil total nitrogen decreased in non-AMF soil, but mycorrhization helped alleviate soil nitrogen limitation. Levels of beta-glucosidase and protease activities were significantly increased by nighttime and dual daytime/nighttime eCO(2) in both AMF and non-AMF soils. With greater effects observed in AMF soils, GRSPs were positively related to mycorrhization, soil organic carbon, total nitrogen, and beta-glucosidase activity, indicating their importance under rising global CO2 levels.

Summary: This study assessed the influence of nitrogen deposition on glomalin-related soil protein (GRSP) and microbial residual carbon (MRC) as sources of soil organic carbon (SOC). The results showed that although total GRSP, MRC, and SOC concentrations were higher under nitrogen deposition, this was mainly due to long-term accumulation and reduced microbial degradation. The relative contributions of GRSP or MRC to SOC did not change or were lower compared to the controls.

Summary: Soil organic carbon (SOC) is crucial for supporting ecosystem functions and services, but its content and distribution are uncertain after the conversion of primary forests to plantations and secondary forests. Our study in subtropical China found that SOC content differed significantly between forest types and soil depths, with primary and secondary forests having higher SOC content than Chinese fir plantations in topsoil. However, SOC content did not increase with stand age within plantations or secondary forests. We also found that mineral-associated organic carbon was higher in Chinese fir plantations, indicating a need to conserve primary forests and protect secondary forests and plantations.

Summary: Plant species diversity (PSD) has beneficial effects on soil organic carbon (SOC) accumulation, and this study explores the mechanisms underlying the stimulative effects of PSD on SOC pools in a subtropical forest. The study finds that PSD enhances soil lignin accumulation through three mechanisms: stimulating plant detritus inputs, increasing reactive minerals for enhanced lignin protection, and lowering microbial C limitation for reduced lignin degradation. These findings provide valuable insights into SOC dynamics under PSD alteration and can be integrated into Earth system models for more accurate predictions.

Summary: Isolating soil organic carbon (SOC) from soil inorganic carbon (SIC) is necessary for quantifying SOC stocks and understanding SOC dynamics. Different methods of SIC removal can introduce biases in SOC measurements, especially when experimental treatments such as elevated atmospheric CO2 alter SOC concentration and composition. This study compares two commonly used methods of SIC removal and finds that acid washing underestimates SOC compared to acid fumigation, particularly in control CO2 plots. These results suggest that acidification disrupts stabilization mechanisms under elevated CO2 treatment.

Summary: Plant tolerance to aluminum toxicity can be enhanced by ectomycorrhizal fungi through biological filtering or physical blockage. This study found that the ectomycorrhizal fungus Lactarius deliciosus was more effective than Pisolithus tinctorius in improving biomass and aluminum tolerance of Pinus massoniana seedlings. The increased aluminum tolerance was attributed to lower absorption capacity, fewer available active sites, decreased affinity and boundary layer thickness for aluminum, and higher aluminum accumulation and translocation in the ECM-inoculated seedlings. These findings contribute to our understanding of the mechanisms and strategies of plant aluminum tolerance conferred by ECM fungi and suggest that inoculation with Lactarius deliciosus is more beneficial for forest plantation and ecosystem restoration in acidic soils, especially in Southwest China and similar soils worldwide.

Summary: The effects of elevated CO2 (eCO2) on paddy soil microbial communities are unclear, especially in different rice cultivars. This study compared the responses of soil bacterial communities to eCO2 and ambient CO2 (aCO2) in two weakly CO2-responsive and two strongly CO2-responsive rice cultivars. The results showed that eCO2 increased differences in bacterial diversity and had positive impacts on soil organic carbon and bacterial abundances. However, eCO2 did not significantly affect the relationship between bacterial diversity and rice yields.

Summary: In a greenhouse study, the effects of Tuber indicum (Chinese black truffle) and T. lijiangense (Chinese white truffle) colonization on Castanopsis rockii host growth, physiological responses, and mycorrhizosphere bacterial communities were compared. Both truffle species increased leaf photosynthetic rate, leaf P concentration, acid phosphatase activity, and bacterial richness of the mycorrhizosphere. However, T. indicum colonization decreased tartrate content, bacterial acid phosphatase, phoC gene abundance, and peroxidase (POD) activity of ectomycorrhizal root tips, but increased mycorrhizosphere pH and superoxide dismutase (SOD) of ectomycorrhizal root tips compared to T. lijiangense colonization. Mycorrhizosphere bacterial community composition also differed significantly between the two truffle species. The bacterium Agromyces cerinus showed a significant correlation with acid phosphatase activity and leaf P concentration, indicating its potential role in phosphorus mobilization and acquisition.

Summary: Cities play a central role in carbon emissions and water consumption, and their development is closely connected to carbon-water coupling. However, little is known about the changes in this relationship during urbanization. In the case of Chengdu-Chongqing urban agglomeration in China, carbon-water coupling during urbanization has contributed to achieving the government's goals of carbon peaking by 2030 and carbon neutralization by 2060. Economic growth has been a major driver of increased carbon emissions and water use, with intensity effect helping to mitigate their growth. The decoupling between CO2 emissions and the economy has been increasing, while the coupling between water use and the economy has been strengthening. Therefore, although CCUA has partially achieved its low-carbon target, more attention should be given to water-saving strategies.

Summary: Soil microbial community coalescence, the mixing and interaction of microbial communities, has been found to enhance the stability and complexity of rhizobacterial networks, leading to improved plant health and biomass. This study investigated the effects of different degrees of bacterial community coalescence on plant disease resistance by mixing soils from healthy and diseased habitats for watermelon planting. The results showed that mixing in more healthy soil reduced the plant disease index and increased biomass by improving the stability and complexity of the rhizobacterial network. Core taxa Nitrospirillum and Singulisphaera were enriched in the rhizosphere from healthy soils and played important roles in disease suppression and regulating the positive cohesion and modularity of the networks. Overall, these findings provide insights into the potential mechanism of microbial community coalescence for improving plant microbial community function and suggest new tools for enhancing plant fitness via soil microbiota mixing.

Summary: Collembolans, the diverse group of soil invertebrates, are affected by anthropogenic climate warming, which alters their diversity and density. In addition to abiotic stressors, changes in food availability, specifically the abundance of saprotrophic and mycorrhizal fungi, influence Collembola responses to climate warming. Collembolans prefer saprotrophic fungi but rely on mycorrhizal fungi when food sources are scarce. Understanding the mechanisms behind these dietary shifts in warm-dry and warm-wet soil conditions is crucial for predicting the impact of climate change on Collembola-fungal interactions.
