Quantification and mapping of the nutrient regulation ecosystem service demand on a local scale

Ecosystems and People, 2020
In this study, the nutrient regulation ecosystem service (ES) demand was quantified and mapped in an agriculturally-dominated landscape in the federal German state of North Rhine-Westphalia.

Disrupting hierarchical control of nitrogen fixation enables carbon-dependent regulation of ammonia excretion in soil diazotrophs.

PLoS Genetics, 2021
The energetic requirements for biological nitrogen fixation necessitate stringent regulation of this process in response to diverse environmental constraints.

Nitrogen and Carbon Status Are Integrated at the Transcriptional Level by the Nitrogen Regulator NtrC In Vivo

mBio, 2013
Nitrogen regulation in Escherichia coli is a model system for gene regulation in bacteria. Growth on glutamine as a sole nitrogen source is assumed to be nitrogen limiting, inferred from slow growth and strong NtrB/NtrC-dependent gene activation. However,

The Growth and Conidiation of Purpureocillium lavendulum Are Co-Regulated by Nitrogen Sources and Histone H3K14 Acetylation

Journal of Fungi, 2023
Plant-parasitic nematodes cause severe economic losses to agriculture. As important biocontrol agents, nematophagous fungi evolved the ability to obtain nitrogen sources from nematodes.

Regulation of nitrogen fixation in Rhizobium sp [PDF]

Applied and Environmental Microbiology, 1976
Regulation of nitrogen fixation by ammonium and glutamate was examined in Rhizobium sp. 32H1 growing in defined liquid media. Whereas nitrogenase synthesis in Klebsiella pneunoniae is normally completely repressed during growth on NH4+, nitrogenase activity was detected in cultures of Rhizobium sp. grown with excess NH4+.

Nitrogen Regulates AMPK to Control TORC1 Signaling [PDF]

Current Biology, 2015
Cell growth and cell-cycle progression are tightly coordinated to enable cells to adjust their size (timing of division) to the demands of proliferation in varying nutritional environments. In fission yeast, nitrogen stress results in sustained proliferation at a reduced size.Here, we show that cells can sense nitrogen stress to reduce target of ...

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Using APSIM Model to Optimize Nitrogen Application for Alfalfa Yield Under Different Precipitation Regimes

Agriculture
Scientific nitrogen management is essential for maximizing crop growth potential while minimizing resource waste and environmental impacts. Alfalfa (Medicago sativa L.) is the most widely cultivated high-quality leguminous forage crop globally, and is ...
