MetabolomicsLinking soil biology and chemistry in biological soil crust using isolate exometabolomics
Metagenomic sequencing provides a window into microbial community structure and metabolic potential; however, linking these data to exogenous metabolites that microorganisms process and produce (the exometabolome) remains challenging. Previously, we observed strong exometabolite niche partitioning a...

MetabolomicsLegume rhizodeposition promotes nitrogen fixation by soil microbiota under crop diversification

Biological nitrogen fixation by free-living bacteria and rhizobial symbiosis with legumes plays a key role in sustainable crop production. Here, we study how different crop combinations influence the interaction between peanut plants and their rhizosphere microbiota via metabolite deposition and ...

MetabolomicsHierarchical Carbon Metabolism in Iron-Deficient Bacteria Favors Iron-Scavenging Strategy

High-affinity iron (Fe) scavenging compounds, or siderophores, are widely employed by soil bacteria to survive scarcity in bioavailable Fe. Siderophore biosynthesis relies on cellular carbon metabolism, despite reported decrease in both carbon uptake and Fe-containing metabolic proteins in Fe-def...

MetabolomicsSoil microbial adaptation to carbon deprivation: Shifts in lignocellulolytic gene profiles following long-term plant exclusion

Background:

Lignocellulose represents a primary input of organic carbon (C) into soils, yet the identity of specific microorganisms and genes which drive lignocellulose turnover in soils remain poorly understood. To address this knowledge gap, we used a 10-year grassland plant-exclusion exp...

MetabolomicsExploring the Interspecific Interactions and the Metabolome of the Soil Isolate Hylemonella gracilis
Analysis of aquatic microbial communities revealed that parts of its diversity consist of bacteria with cell sizes of ~0.1 μm. Such bacteria can show genomic reductions and metabolic dependencies with other bacteria. So far, no study investigated if such bacteria exist in terrestrial environments e....

TranscriptomicsMicroarray analysis of high Arctic soil bacterial response to hydrocarbon pollution and bioremediation: 16S rRNA
High Arctic soils have low nutrient availability, low moisture content and very low temperatures and, as such, they pose a particular problem in terms of hydrocarbon bioremediation. An in-depth knowledge of the microbiology involved in this process is likely to be crucial to understand and optimize ...

MetabolomicsEcological effects of water and fertilizer coupling on poplar planting soil

While irrigation and fertilization are basic cultivation practices in poplar plantations on a global scale, the impact of these practices on the environment is not well understood. Here, we demonstrate that water-urea coupling and water-compound fertilizer coupling differentially impact soil ecos...

MetabolomicsOrganic fertilizer amendments reshape soil microbial communities and metabolic functions in sweet cherry production
Soil microorganism and metabolite-mediated root-soil interactions play a pivotal role in regulating fertilizer utilization efficiency and sweet cherry growth. Four treatment groups were established: a control group (CK, garden soil with conventional fertilization) and three amended groups (T1: sheep...
