Identity of active methanotrophs in landfill cover soil as revealed by DNA-stable isotope probing

, 2014
A considerable amount of methane produced during decomposition of landfill waste can be oxidized in landfill cover soil by methane-oxidizing bacteria (methanotrophs) thus reducing greenhouse gas emissions to the atmosphere. The identity of active methanotrophs in Roscommon landfill cover soil, a slightly acidic peat soil, was assessed by DNA-stable ...

Stable-isotope probing as a tool in microbial ecology

Microorganisms are responsible for driving the biogeochemical cycling of elements on Earth. Despite their importance and vast diversity(1), the taxonomic identity of the microorganisms involved in any specific process has usually been confined to that ...

Combining eDNA metabarcoding and stable isotope analysis advances diet studies in a colonial, non‐regurgitating seabird

Ibis, EarlyView.
Understanding seabird diet is fundamental to assessing trophic interactions and predicting responses to environmental change. However, seabird diet studies are often constrained by low taxonomic resolution, invasive sampling methods or reliance on opportunistically collected samples, leaving the diet of important populations such as Common Guillemots ...

Experimental and genomic evidence clarifies the mycorrhizal helper role of a widespread bacterium in Bishop pine forests

New Phytologist, EarlyView.
Hypothetical model of Paraburkholderia–EcMF–Bishop pine interactions. Summary Whether a widespread bacterial strain of Paraburkholderia can enhance the physiological responses of ectomycorrhizal fungi (EcMF) and host Bishop pine seedling growth remains unclear. We developed a ‘top‐down meets bottom‐up’ approach that harmonized data from molecular field

Recent plant photosynthate as a driver of ecological and evolutionary processes

New Phytologist, EarlyView.
Timeline of key eco‐evolutionary outcomes arising from belowground allocation of recent plant photosynthate from shoots. Summary Plants rapidly allocate carbon from photosynthesis belowground via root exudates and root‐associated microorganisms. Here we synthesise recent evidence of our understanding of the consequences of this ‘fast’ pathway of recent

Integrated Metabolomics and Selection Signal Analysis Provide Insights Into the Selection for Flavonol Biosynthesis Associated With Lettuce Quality Improvement

Plant Biotechnology Journal, EarlyView.
ABSTRACT Lettuce is a critical leafy vegetable consumed worldwide and is a substantial dietary source of health‐promoting compounds. Exploring changes in metabolism during lettuce domestication under artificial selection conditions is important to facilitate further breeding and cultivation for quality improvement.

Virocell Necromass Provides Limited Plant Nitrogen and Elicits Rhizosphere Metabolites That Affect Phage Dynamics

Plant, Cell &Environment, EarlyView.
ABSTRACT Bacteriophages impact soil bacteria through lysis, altering the availability of organic carbon and plant nutrients. However, the magnitude of nutrient uptake by plants from lysed bacteria remains unknown, partly because this process is challenging to investigate in the field.

Selective photo labeling of tryptophan in N‐acetyl‐L‐tryptophan ethyl ester and peptide WWCNDGR with a diaryl nitrenium ion

Photochemistry and Photobiology, EarlyView.
Visible light photolysis of a N‐(N,N‐diarylaminopyridinium) salt allows for covalent modification of a peptide. Mass spectrometry demonstrates that this procedure selectively labels tryptophan residues. Laser flash photolysis experiments show that bond formation occurs via a diarylnitrenium ion intermediate.

Scaling temporal resolution from mice to humans: Challenges and innovations in preclinical imaging of translational models

The Journal of Physiology, EarlyView.
Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...

Clinical Laboratory Innovations: Nanoscale Detection of Chloramphenicol Using Nanomaterial Biosensors

Analytical Science Advances, Volume 7, Issue 2, December 2026.
Nanosensor schematic functionalized with specific bioreceptors that produce electrochemical signals upon Chloramphenicol binding. Resulting voltammetric readouts (differential pulse, square‐wave, and cyclic voltammetry) are analyzed to identify and quantify Chloramphenicol.
