Molybdenum--substrate interactions in nitrogenase: an EXAFS study [PDF]

, 1978
The sensitivity of x-ray absorption edge spectra and extended x-ray absorption fine structure (EXAFS) to the environment of metal atoms make x-ray absorption spectroscopy a useful probe of the environment of the molybdenum in nitrogenase.

Evaluation of Salt‐Tolerant Guar (Cyamopsis tetragonoloba L.) Genotypes Based on Physiological, Biochemical, and Yield‐Related Traits

Legume Science, Volume 8, Issue 2, June 2026.
ABSTRACT The 15 guar genotypes were exposed to different concentrations of salt (0, 10, and 15 dS m−1 NaCl) in a factorial experiment (RCBD, r = 3) and different morpho‐physiological, physiological, growth, and yield characteristics were assessed. The lowest seed gum (21.11%), carbohydrate (23.59%), protein content (24.20%), fat (2.21%), fiber (9.38%),

Functional Metagenomics Insights Into the Allium ampeloprasum Rhizosphere Microbiome Under Different Fertilization Regimes

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Shotgun metagenomic sequencing was used to characterize the functional potential of the Allium ampeloprasum rhizosphere microbiome under chemical fertilizer (G1), biofertilizer (G2), and unfertilized (Bulk) soil (G3) management practices. This study revealed that different fertilization regimes altered microbial functional profiles.

Genetic analysis of the NifM dependence of the nitrogenase iron proteins

mBio
NifH maturation in certain diazotrophic bacteria depends on NifM, a protein with a PpiC-isomerase domain. Intriguingly, the putative proline substrate for NifM is present in NifH proteins from strains lacking nifM, raising questions regarding the actual ...

Influence of Cowpea Plants on Soil Bacterial Community and Soil Quality: Effects of the Rhizosphere

Plant-Environment Interactions, Volume 7, Issue 3, June 2026.
ABSTRACT Cowpea (Vigna Unguiculata), a vital legume for suitable agriculture and food security in sub‐Saharan Africa, plays a crucial role in improving soil health through intricate plant‐microbe interactions in the rhizosphere. This review synthesizes current knowledge on the microbial interactions in the rhizosphere, focusing on soil health ...

Temperature‐Dependent Effects of Laboratory‐Heated Dissolved Organic Matter on Aquatic Microbiome Composition and Nitrogen Cycling Dynamics

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Wildfires generate partially combusted biomass that mobilizes to aquatic ecosystems as dissolved pyrogenic organic matter (dPyOM) in runoff, where it can impact surface water quality. However, the influence of dPyOM on aquatic microbiome composition, functional gene distribution, and biogeochemical processes remains poorly understood, with ...

Natural and Engineered Electron Transfer of Nitrogenase

, 2020
As the only enzyme currently known to reduce dinitrogen (N2) to ammonia (NH3), nitrogenase is of significant interest for bio-inspired catalyst design and for new biotechnologies aiming to produce NH3 from N2. In order to reduce N2, nitrogenase must also

Elucidating the Functional and Taxonomic Diversity of Soil Microbial Communities From Three Commercial Soybean Farms in South Africa

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Prior to inoculation of soybeans, South African soils contain no Bradyhizobia that nodulate and fix nitrogen in soybeans. Soybean cultivation with prolonged inoculation resulted in the establishment and dominance of Bradyrhizobia in three soybean farms in South Africa as revealed by a microbial community study using shotgun metagenomics. ABSTRACT Prior

Molecular Characterization of Nitrogenase Regulation in Methanosarcina acetivorans

, 2022
Nitrogenase is the metalloenzyme only found in bacteria and archaea that is essential for biological nitrogen fixation (diazotrophy), but it can also serve as a catalyst in biofuel production.
