Effect of preceding integrated and organic farming on ${15}_N$ recovery and the N balance, including emissions of $NH_3$ , $N_2O$, and $N_2$ and leaching of $NO_3$$^−$

Ecological intensification strategies in agriculture, including organic fertilization and diversified crop rotations, aim to reduce nitrogen (N) losses to the environment. However, studies on N allocation and loss on adjacent sites with the same pedoclimatic conditions but different management histories, i.e.

Conformational asymmetry of human immunodeficiency virus‐1 protease flaps increases along the darunavir drug resistance pathway

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Under selective drug pressure, the structure and dynamics of HIV‐1 protease (PR) evolve to confer resistance to the drug. Here, we report on the conformational changes in PR flaps for drug‐resistance mutations using 19F nuclear magnetic resonance (NMR) spectroscopy.

Nitrogen‐Starved Wheat: A Multi‐Omics Perspective From Epigenome Regulation to Grain Quality

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
This review establishes epigenetic regulation, specifically H3K27ac and H3K27me3 dynamics at nitrogen transporter, assimilation, and storage protein loci, as a principal determinant of cultivar‐specific nitrogen use efficiency in hexaploid wheat, independent of DNA sequence variation, and identifies the rhizosphere microbiome as an integral but ...

Systems‐Level Plant Responses Reveal Pseudomonas‐Mediated Growth Promotion in Brachypodium Under Nitrogen Limitation

Plant, Cell &Environment, Volume 49, Issue 9, Page 6396-6412, September 2026.
ABSTRACT Plant growth–promoting bacteria can enhance plant performance under nutrient limitation, yet the underlying plant molecular responses remain incompletely resolved. We investigated growth promotion by Pseudomonas koreensis in Brachypodium distachyon under contrasting nitrogen (N) regimes using time‐resolved phenotyping, elemental analysis ...

Heme‐NO Dilates Arteries via Mobilization of NO Moieties From an Intracellular NO Store Within Vascular Smooth Muscle Cells

Advanced Science, Volume 13, Issue 43, 3 August 2026.
Nitrosyl heme emerges as an extracellular nitrodilator that dilates arteries without crossing the cell membrane. Instead, heme‐NO mobilizes NO moieties from a preformed intracellular NO store within vascular smooth muscle, providing both functional and chemical evidence for the NANOS model, revealing a previously unrecognized mechanism of arterial ...
