Rhizosphere priming promotes plant nitrogen acquisition by microbial necromass recycling Open
Nitrogen availability in the rhizosphere relies on root‐microorganism interactions, where root exudates trigger soil organic matter (SOM) decomposition through the rhizosphere priming effect (RPE). Though microbial necromass contribute sig…

Crohn’s disease as the intestinal manifestation of pan-lymphatic dysfunction: An exploratory proposal based on basic and clinical data Open
Crohn’s disease (CD) is caused by immune, environmental, and genetic factors. It can involve the entire gastrointestinal tract, and although its prevalence is rapidly increasing its etiology remains unclear. Emerging biological and small-m…

Soil matrix study using a hybrid a-Se/CMOS pixel detector for CT scanning Open
Computed tomography (CT) is a non-invasive means of localizing a region of interest within an object, which enables the investigation of soil distributions and localized flow processes within soil pore systems. CT scanning allows for cross…

Strong linkage of carbon and nitrogen mineralization in rhizosphere soils along an altitudinal forest gradient of Changbai Mountain Open
Aims Rhizosphere is a hotspot for soil C and N biogeochemical cycling in terrestrial ecosystems. Our understanding of interaction between C and N mineralization mainly comes from the bulk soils, yet it is unknown the interaction in the rhi…

Long-Term Bare Fallow Soil Reveals The Temperature Sensitivity of Priming Effect of The Relatively Stabilized Soil Organic Matter Open
Priming plays an important role in modifying the decomposition of soil organic matter (SOM), but there are large uncertainties in the temperature effect on priming mainly due to the variation in SOM stability. Long-term bare fallow offers …

Root effects on soil organic carbon: a double‐edged sword Open
Summary From recent developments on how roots affect soil organic carbon (SOC) an apparent paradox has emerged where roots drive SOC stabilization causing SOC accrual, but also SOC destabilization causing SOC loss. We synthesize current re…

Rhizosphere priming effects in soil aggregates with different size classes Open
The change in native soil organic carbon ( SOC ) decomposition caused by plant roots or the rhizosphere priming effect ( RPE ) is a common phenomenon. Although most of the SOC is stored in aggregates with different size classes, the RPE in…

Improved root turnover assessment using field scanning rhizotrons with branch order analysis Open
Root turnover is a key process contributing to soil carbon storage, nutrient cycling, and other ecosystem functions. However, quantifying root turnover rates remains highly uncertain and methodologically challenging. Field rhizotrons were …

Aridity thresholds of soil microbial metabolic indices along a 3,200 km transect across arid and semi-arid regions in Northern China Open
Soil microbial processes are crucial for understanding the ecological functions of arid and semi-arid lands which occupy approximately 40% of the global terrestrial ecosystems. However, how soil microbial metabolic activities may change ac…

Stable isotopic constraints on global soil organic carbon turnover Open
Carbon dioxide release during soil organic carbon (SOC) turnover is a pivotal component of atmospheric CO2 concentrations and global climate change. However, reliably measuring SOC turnover rates on large spatial and temporal scales remain…

Priming effects on labile and stable soil organic carbon decomposition: Pulse dynamics over two years Open
Soil organic carbon (SOC) is a major component in the global carbon cycle. Yet how input of plant litter may influence the loss of SOC through a phenomenon called priming effect remains highly uncertain. Most published results about the pr…

Habitat-specific patterns and drivers of bacterial β-diversity in China’s drylands Open
The existence of biogeographic patterns among most free-living microbial taxa has been well established, yet little is known about the underlying mechanisms that shape these patterns. Here, we examined soil bacterial β-diversity across dif…

Factors controlling soil organic carbon stability along a temperate forest altitudinal gradient Open
Changes in soil organic carbon (SOC) stability may alter carbon release from the soil and, consequently, atmospheric CO 2 concentration. The mean annual temperature (MAT) can change the soil physico-chemical characteristics and alter the q…
