Elevated Ozone Concentration and Nitrogen Addition Increase Poplar Rust Severity by Shifting the Phyllosphere Microbial Community

Journal of Fungi, 2022
Tropospheric ozone and nitrogen deposition are two major environmental pollutants. A great deal of research has focused on the negative impacts of elevated O3 and the complementary effect of soil N addition on the physiological properties of trees ...

Seasonal Fluctuations and Ecological Resilience: Grassland-Type-Specific Responses of Soil Carbon and Nitrogen Transformations in a Forest–Steppe Ecotone Under Global Change

Agronomy
Against the backdrop of global climate change, climate warming and increasing nitrogen addition are profoundly altering carbon (C) and nitrogen (N) cycling in terrestrial ecosystems. Short-term observations are critical for capturing the initial response

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Influence of nitrogen water interaction on leaf functional traits of dominant species in warm temperate forest

Forestry Research
Plant functional traits are indicative of plant responses to environmental changes, influencing ecosystem functions. Leaves, as a key focus in studying plant functional traits, present an area where the impact of nitrogen deposition and altered rainfall ...

Effects of nitrogen addition on species composition and diversity of early spring herbs in a Korean pine plantation

Ecology and Evolution, 2023
Under the background of global nitrogen deposition, temperate forest ecosystems are suffering increasing threats, and species diversity is gradually decreasing. In this study, nitrogen addition experiments were conducted on Korean pine (Pinus koraiensis)

Effect of combined nitrogen on symbiotic nitrogen fixation in pea plants [PDF]

, 1979
The nitrogen-fixing activity of the symbiotic system of Pisum sativum with Rhizobium leguminosarum is adversely affected by combined nitrogen. Both ammonium chloride and potassium nitrate, when added to the roots, lower the nitrogenase activity ...

Grassland biodiversity bounces back from long-term nitrogen addition

, 2015
The negative effect of increasing atmospheric nitrogen (N) pollution on grassland biodiversity is now incontrovertible. However, the recent introduction of cleaner technologies in the UK has led to reductions in the emissions of nitrogen oxides, with ...
