Ecological niches and biogeography of nitrogen‐fixing plants in Europe

Plant Biology, EarlyView.
Despite sharing N fixation as a common trait, European legume and actinorhizal plant lineages occupy strikingly divergent ecological niches shaped by their evolutionary histories and physiological adaptations. Advanced symbiont control allows IRLC legumes to expand into northern, mesic regions, while non‐IRLC legumes are more common in Mediterranean ...

Structural basis for the conformational protection of nitrogenase from O2 [PDF]

Structural Dynamics
The low reduction potentials required for the reduction of dinitrogen (N2) render metal-based nitrogen-fixation catalysts vulnerable to irreversible damage by dioxygen (O2).

Photosynthesis regulation impacts carbon and nitrogen assimilation in the diazotrophic cyanobacterium Anabaena sp. PCC 7120

New Phytologist, Volume 251, Issue 1, Page 94-110, July 2026.
Model of intercellular functional coordination in Anabaena. Summary Diazotrophic cyanobacteria fix both atmospheric carbon (C) and nitrogen (N) into biomass, but the two assimilation pathways are not compatible. Species like Anabaena sp. PCC 7120 physically separate C and N assimilation in different cell types.

CHAPTER 9 Biosynthesis of the M-Cluster of Mo-Nitrogenase

, 2017
The nitrogenase complex is responsible for the reduction of an inert gas, dinitrogen (N2), to a bioavailable form of nitrogen, ammonia (NH3). At the heart of the catalytic component of molybdenum (Mo) nitrogenase resides the iron-molybdenum (FeMo ...

Endophyte‐induced systemic spatial reprogramming of metabolism in Populus trichocarpa roots under drought

New Phytologist, Volume 251, Issue 1, Page 438-454, July 2026.
Summary Beneficial, facultative endophytes help plants thrive in challenging environments by altering their host's metabolism, but how these cellular scale metabolic changes propagate to the systems biology scale is unknown. In this work, we employed a high‐resolution chemical imaging approach to map metabolic changes at the Populus trichocarpa root ...

Comparative proteomics analysis of root and nodule mitochondria of soybean

Plant, Cell &Environment, Volume 49, Issue 7, Page 3482-3499, July 2026.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

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.
