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...

MetabolomicsNew insights into the responses of soil microorganisms to polycyclic aromatic hydrocarbon stress by combining enzyme activity and sequencing analysis with metabolomics
Polycyclic aromatic hydrocarbons (PAHs), some of the most widespread organic contaminants, are highly toxic to soil microorganisms. Whether long-term polluted soils can still respond to the fresh input of pollutants is unknown. In this study, the soil enzyme activity, soil microbial community struct...

MetabolomicsNano-silicon dioxide reduced soil organic pollutant contents

Composite organic pollutant residues had caused considerable threats to soil systems, and the nano-SiO2 could decrease composite organic pollutant residue dissipations in soil systems

MetabolomicsNucleotide depletion signals early-stage soil stable carbon collapse in anthropogenically disturbed alpine ecosystems
Anthropogenic disturbances are a primary cause of soil organic carbon (SOC) destabilization in alpine ecosystems. However, effective management is hindered by a """"response delay"""" of macro metrics used to characterize stable carbon pools (e.g., microbial necromass carbon and aggregate associated...

MetabolomicsThe influence of different microplastics on soil metabolic processes
We investigated the changes in soil microorganisms and their metabolic processes under microplastic pollution by adding different types and concentrations of microplastics (polypropylene plastic, polyethylene terephthalate plastic, polyhexanediol/caprolactone microplastics) to agricultural soil.

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 ...

MetabolomicsSoil metabolomics profiling across contrasting forest types in subtropical China

This study provides an untargeted LC–MS metabolomics dataset generated from soils collected across contrasting forest types. The dataset captures broad soil metabolite profiles across forest types with contrasting litter quality, soil structure, and microbial environments, and can support multipl...

MetabolomicsUnlocking soil carbon potential in giant panda habitat

Forest management in giant panda habitats necessitates strategies that simultaneously support biodiversity and ecosystem carbon sequestration. Here, we demonstrate that protecting understory vegetation is indispensable for sustaining the soil carbon sink in restored subalpine coniferous plantatio...

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...

MetabolomicsA Comprehensive and Ultrasensitive Isotope Calibration Method for Soil Amino Compounds Using Orbitrap Mass Spectrometry
Bound amino compounds (amino acid and amino sugar polymers) comprise a significant proportion (~40%) of soil organic nitrogen and therefore represent an essential source of nitrogen for plant and microbial nutrition. The analysis of their content and isotope enrichment still represents a significant...
