Anthropogenic climate change may reduce global diazotroph diversity [PDF]
Nature CommunicationsClimate change impacts microbial community structure and function, thus altering biogeochemical cycles. Biological nitrogen fixation by diazotrophs is involved in maintaining the balance of the global nitrogen cycle, but the global biogeographic patterns

Unlocking nitrogen regulation: structural insights into the NifL-NifA complex and prospects for engineered diazotrophs. [PDF]
FEBS JThe urgent need for sustainable agriculture places biological nitrogen fixation at the forefront of current biotechnological research. Plant growth‐promoting rhizobacteria play crucial roles in agriculture by enhancing nutrient absorption, regulating hormonal balance, and providing reduced nitrogen to plants. Among these, diazotrophic bacteria, such as

Enhancing biological nitrogen fixation in rice paddy ecosystems: challenges, opportunities, and sustainable strategies [PDF]
Frontiers in MicrobiologySynthetic nitrogen (N) fertilizers have substantially increased rice (Oryza sativa) yields but at the expense of low N use efficiency, significant environmental losses, and deterioration of soil health.

Genetic and physiological insights into the diazotrophic activity of a non-cyanobacterial marine diazotroph [PDF]
Environmental Microbiology, 2022 AbstractNitrogen (N2) fixation, or diazotrophy, supports a large part of primary production in oceans. Culture-independent approaches highlighted the presence in abundance of marine non-cyanobacterial diazotrophs (NCD) but their ecophysiology remains elusive, mostly because of the low number of isolated NCD and because of the lack of available genetic ...

nifH gene expression and diversity in geothermal springs of Tengchong, China
Frontiers in Microbiology, 2022 Terrestrial hot springs have been suggested to harbor diverse diazotrophic lineages by using DNA-based nifH gene phylogenetic analysis. However, only a small amount of diazotrophs were ever confirmed to perform nitrogen fixation.

Temporal dynamics of total and active root-associated diazotrophic communities in field-grown rice
Frontiers in Microbiology, 2022 Plant-associated nitrogen-fixing microorganisms (diazotrophs) are essential to host nutrient acquisition, productivity and health, but how host growth affects the succession characteristics of crop diazotrophic communities is still poorly understood ...

Can Top-Down Controls Expand the Ecological Niche of Marine N2 Fixers?
Frontiers in Microbiology, 2021 The ability of marine diazotrophs to fix dinitrogen gas (N2) is one of the most influential yet enigmatic processes in the ocean. With their activity diazotrophs support biological production by fixing about 100–200 Tg N/year and turning otherwise ...

Diazotrophic Anaeromyxobacter Isolates from Soils [PDF]
Applied and Environmental Microbiology, 2020 Anaeromyxobacter is globally distributed in soil environments, especially predominant in paddy soils. Current studies based on environmental DNA/RNA analyses frequently detect gene fragments encoding nitrogenase of Anaeromyxobacter from various soil environments.
