Physiology of nitrogen: A life or death matter
Experimental Physiology, EarlyView.Abstract With each breath, four out of every five molecules we inspire are nitrogen (N2), since this gas constitutes ∼80% of the atmospheric air that surrounds us. Despite its abundance and unlike molecular oxygen, N2 has traditionally held less appeal among physiologists given its lack of reactivity and corresponding inability to support combustion or

Expression Map for Genes Involved in Nitrogen and Carbon Metabolism in Alfalfa Root Nodules
Molecular Plant-Microbe Interactions, 1999 During root nodule development several key genes involved in nitrogen fixation and assimilation exhibit enhanced levels of expression. However, little is known about the temporal and spatial distribution patterns of these transcripts.

Nickel application influences nitrogen concentration, yield, and grain quality of soybean
Crop, Forage &Turfgrass Management, Volume 11, Issue 2, December 2025.Abstract Nickel (Ni) is an essential element in nitrogen (N) metabolism. This study evaluated the effects of foliar fertilization with Ni on the grain yield (GY), yield components, N content, grain protein, and oil content of soybean [Glycine max (L.) Merr].

Modeling physiological processes in plankton on enzyme kinetic principles
Scientia Marina, 2004 Many ecologically important chemical transformations in the ocean are controlled by biochemical enzyme reactions in plankton. Nitrogenase regulates the transformation of N2 to ammonium in some cyanobacteria and serves as the entryway for N2 into the ...

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.ABSTRACT Introduction Agricultural crops face increasing environmental stresses, such as soil salinity and heavy metal contamination, aggravated by climate change and threatening food security. While PGPRs are eco‐friendly agrochemical substitutes, their efficacy in the field is inconsistent.

MicroRNAs‐mediated heat stress regulations in plants: Mechanisms and targets
The Plant Genome, Volume 18, Issue 4, December 2025.Abstract Heat stress, exacerbated by global warming, can cause significant challenges to agriculture, adversely impacting plant growth, reproduction, and yield. This review examines the crucial role of microRNAs (miRNAs) in mediating plant responses to heat stress across various key crops, including Arabidopsis (Arabidopsis thaliana), rice (Oryza ...
