Summary: This study investigated fungal CO2 fixation in 29 soil samples collected from the major agricultural regions across China. The results revealed variations in fungal fixation by 2.2 to 65.5% of the total microbial CO2 fixation. Trichocladium uniseriatum was found to have the highest CO2 fixation capacity among the tested fungal strains, using the reductive tricarboxylic acid cycle (rTCA) for CO2 assimilation associated with sulfite metabolism. Soil inoculation experiments showed that 77-82% of the fixed carbon by T. uniseriatum was partitioned into the mineral-associated soil organic carbon. This study highlights the significance of fungal CO2 fixation in soil carbon sequestration.

Summary: The study found that biochar did not affect the distribution of C-13 in plants, but reduced the total C-13 content in the soil. Biochar altered the microbial community structure in the soil, decreasing fungi and increasing the relative abundance of bacteria. Fungi contributed more to C-13 sequestration compared to bacteria, and in biochar-amended soil, root-derived substances became less stable.

Summary: An experiment was conducted to study the influence of different CO2 concentrations on microorganisms involved in root-derived C incorporation in greenhouse soil systems. The results showed that fungi played a dominant role in the incorporation of root-derived C under eCO(2) treatment, while actinomycetes only appeared on day 15 under eCO(2) treatment. This indicates that eCO(2) significantly affected microbial biomass and community structures involved in the incorporation of C-13-CO2 via tomato root secretions.

Summary: The study found that N deposition has a significant impact on the accumulation of soil microbial residues and their contribution to SOC in different forest ecosystems, specifically affecting the fungal residues and bacterial residues in various forest types. The responses of microbial residue-C in SOC to N addition are dependent on changes in soil total N concentration and the fungi to bacteria ratio under N addition and climate conditions.

Summary: In this study, the response of the rhizomicrobiome in agricultural soil to global change was investigated. Elevated CO2 showed positive effects on bacterial abundance and above-ground plant biomass, while drought had negative effects on bacterial abundance under elevated CO2 conditions. Warming and N-fertilizer supplies increased bacterial abundance and community composition, but these responses were not influenced by CO2. The research provides evidence that the rhizomicrobiome in wheat plants can be affected by elevated CO2 levels, with additional drought conditions altering these effects.

Summary: This study investigated the effect of elevated CO2 on phosphorus (P) requirement for enhanced N2 fixation in white lupin plants. The results showed that elevated CO2 increased the critical P concentration needed for N2 fixation, indicating that more P is required to support greater N2 fixation under elevated CO2. Additionally, elevated CO2 improved N2 fixation in P-deficient plants by increasing nitrogenase activity and excess cation uptake.

Summary: Atmospheric CO2 enrichment, largely caused by human activities, affects sediment microbial communities in plant rhizospheres. This study aimed to evaluate this interaction in Spartina maritima rhizosediments and investigate the impacts of increased atmospheric CO2 on biogeochemical processes. Mesocosm trials were conducted using salt marsh cores exposed to 410 and 700 ppm CO2, and rhizosediment extracellular enzymatic activities were assessed. The results showed an increase in dehydrogenase and phosphatase activity under elevated CO2, indicating a priming effect and higher phosphate requirements for microbial activity. Sulphatase activity also increased, suggesting sulphur limitation due to elevated CO2. Protease activity decreased, possibly due to increased amino acid synthesis and acquisition needs. Carbon-related enzymes generally increased under higher CO2 levels. The altered recycling activity of organic compounds may disrupt biogeochemical cycles and affect rhizosphere ecosystem function and ecosystem services.

Summary: Here, a methodology for accessing isotopically labeled esters and amides from carbonates and carbamates utilizing an oxygen deletion strategy is reported. The methodology employs a decarboxylative carbonylation approach using C-12 or C-13 carbon monoxide generated ex situ in near stoichiometric amounts for isotope labeling. The reaction demonstrates a broad scope, functional group tolerance, and high yields, exemplified by the synthesis of structurally complex molecules. Additionally, a complementary method for the catalytic in situ generation of CO from CO2 liberated during decarboxylation is developed as a proof-of-concept approach for converting CO2-derived compounds to CO-containing frameworks. Mechanistic studies provide insights into the catalytic steps and the impact of ligand choice for overcoming challenges in low-pressure carbonylation methodologies, aiding the development of future methodologies.

Summary: Soil carbon plays a crucial role in long-term climate change; it can either mitigate global warming by carbon sequestration or exacerbate warming through greenhouse gas emissions. This study evaluated the impact of fertilization strategies on inorganic carbon content and stocks in soil. Fertilization with mineral nitrogen and phosphorous acidified soils, leading to the dissolution of inorganic carbon and carbon dioxide emissions. However, manure application increased inorganic carbon stock through the formation of pedogenic carbonates and preservation of lithogenic carbonates. Combining manure with mineral fertilizers provided an optimal solution to mitigate carbon losses from soil.

Summary: Vegetation restoration has significant effects on belowground microbial diversity, trait-based life strategies, and soil organic matter accumulation. The relationship between SOM accrual and life strategies following vegetation restoration remains unclear. This study used multiple approaches to examine these relationships, and found that vegetation restoration increased SOM accrual and shifted bacterial communities towards K-strategists. The decline in labile nutrient content and increase in carbon stability after vegetation restoration were the main drivers of these changes. Understanding the link between bacterial life strategies and SOM accrual is crucial for studying soil-microbial interactions.

Summary: Changes in rice root morphology reflect the decrease in phosphorus (P) deficiency after the dissolution of ferric iron (Fe(III))-bound phosphate (Fe-P) in low-redox paddy soils. A new in-situ 32P phosphor-imaging approach was developed to estimate P uptake by rice roots released from Fe-P dissolution. Direct root access to Fe-P increased rice crown roots elongation, branching, and P accessibility under P deficiency.

Summary: Soil microbial communities are influenced by soil types and land use. This study investigated contrasting soils of natural forest and cropped vineyard in New South Wales, Australia and found that land use affected the bacterial community distribution in the topsoil, while soil types influenced the assembly of microbial communities in the subsoil. The study also revealed a decrease in topsoil organic carbon in the vineyard compared to the forest, which was correlated with changes in C-related genes and potentially accelerated carbon loss.

Summary: Tropical forests, which are nitrogen rich but phosphorus poor, play a crucial role in global carbon and nitrogen cycling. This study found that nitrogen deposition can stimulate soil organic matter mineralization and nitrogen and phosphorus cycling, while phosphorus addition can alleviate the nitrogen-induced effects and promote fungal growth and reduce greenhouse gas emissions. Further research is needed to understand the seasonal and annual variations in greenhouse gas emissions and to predict and model the dynamics of carbon and nitrogen cycling.

Summary: The priming effects of soil organic matter (SOM) decomposition influenced by fertilizers affect carbon balance and nutrient release. Nitrogen (N) and phosphorus (P) limitation in Tibetan meadows can retard SOM decomposition, but N and P fertilization can alleviate this limitation and induce priming effects. P fertilization has the highest priming effect and the lowest SOM storage.

Summary: After cropland abandonment, increased plant carbon input into the soils leads to both carbon accumulation and higher microbial activities, resulting in faster organic matter decomposition. Our study on a chronosequence of post-agricultural self-restoration of Luvisols showed that microbial biomass carbon and enzyme activities increased in the top soil during the 37-year period of self-restoration. Microbial activity was more sensitive to land use changes compared to soil organic carbon. The quantity and quality of plant carbon inputs regulated microbial activity and enzyme production, providing insights into ecosystem succession.

Summary: Precipitation changes have significant impacts on the carbon, nitrogen, and phosphorus cycles in terrestrial ecosystems. This study analyzed a large number of observations from field studies to investigate the effects of increased and decreased precipitation on the stoichiometry of plants, soils, and microorganisms. The results showed that plants were more sensitive to decreased precipitation, while soil microbial communities were more sensitive to increased precipitation. Additionally, soil microorganisms maintained stoichiometric homeostasis, while plants tended to follow the stoichiometry of the soils. These findings highlight the importance of considering specific nutrient allocation strategies of plants and microbial communities in predicting ecosystem functions and carbon cycling under future climate change scenarios.

Summary: The mineralization of dissolved organic matter (DOM) in thermokarst lakes plays an important role in the permafrost carbon cycle, but its complex interactions are not well understood. This study used large-scale lake sampling and laboratory incubations to investigate the patterns and drivers of DOM biodegradation. The results showed that labile carbon (C) and phosphorus (P) inputs stimulated DOM biodegradation, with the combined labile C and nutrient additions inducing stronger microbial mineralization. The intensity of aquatic priming was driven by DOM quality, while the P effect decreased with DOM recalcitrance.

Summary: Carbon use efficiency (CUE) and energy use efficiency (EUE) play important roles in quantifying carbon cycling processes. EUE is at least as important as CUE because microorganisms mainly use organic carbon as an energy source. The mean microbial EUE (0.32-0.35) is 18% lower than CUE (0.41) using glucose as a substrate, indicating that microbial growth is limited by energy relative to carbon.

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.
