Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

open access: yesThe FEBS Journal, EarlyView.
Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...

Molecular Analysis of the Microbial Guild Fixing Nitrogen in Ricefield Soils in Missouri

open access: yesMicrobiology Research
Non-symbiotic diazotrophic microbes are important contributors to global N budgets in cereal crops. Knowledge of the biogeography of the organisms in this functional guild increases our understanding of biological N fixation in diverse locations and ...

Possible association of diazotrophs with marine zooplankton in the Pacific Ocean

open access: yesMicrobiologyOpen, 2016
Dinitrogen fixation, the biological reduction in N2 gas to ammonia contributes to the supply of new nitrogen in the surface ocean. To understand the diversity and abundance of potentially diazotrophic (N2 fixing) microorganisms associated with marine ...

Is plant evolutionary history impacting recruitment of diazotrophs and nifH expression in the rhizosphere?

open access: yesScientific Reports, 2016
Plant evolutionary history influences the taxonomic composition of the root-associated bacterial community, but whether it can also modulate its functioning is unknown.

Unlocking nitrogen regulation: structural insights into the NifL‐NifA complex and prospects for engineered diazotrophs

open access: yesThe FEBS Journal, EarlyView.
The 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

Phosphate solubilizing bacteria stimulate wheat rhizosphere and endosphere biological nitrogen fixation by improving phosphorus content [PDF]

open access: yesPeerJ, 2020
Phosphate (P) availability often limits biological nitrogen fixation (BNF) by diazotrophic bacteria. In soil, only 0.1% of the total P is available for plant uptake.

Nodularia sp. nifH gene transcripts in the Baltic Sea proper [PDF]

open access: yesJournal of Plankton Research, 2007
While bacterioplankton indisputably control vital biogeochemical paths in the cycling of carbon and nutrients in the world’s oceans, our knowledge about the functional and genetic diversity of bacterioplankton communities is negligible. In this thesis, molecular and more traditional microbiological methods were used to study the specific function of N2-

Reprogramming of Gene Transcripts and Metabolites by the Wild Soybean Endophyte Pseudomonas sp. 77S3 Improves Soybean Salt Tolerance

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Soybean is a critical source of protein and vegetable oil worldwide. Expanding its cultivation into salinity lands represents a promising strategy for increasing production; however, soil salinity severely limits soybean growth by disrupting physiological and metabolic homeostasis.

ANALISIS AKTIVITAS NITROGENASE DAN GEN NIFH ISOLAT BAKTERI RHIZOSFER TANAMAN PADI DARI LAHAN SAWAH PESISIR JAWA BARAT

open access: yesAl-Kauniyah Jurnal Biologi, 2016
Abstrak Penambatan nitrogen oleh bakteri rhizosfer dapat dimanfaatkan untuk menyiasati dampak salinitas pada tanah sawah pesisir. Kemampuan tersebut disebabkan oleh aktivitas nitrogenase yang disandikan gen nifH pada komponen II.

Molecular evidence for sediment nitrogen fixation in a temperate New England estuary [PDF]

open access: yesPeerJ, 2016
Primary production in coastal waters is generally nitrogen (N) limited with denitrification outpacing nitrogen fixation (N2-fixation). However, recent work suggests that we have potentially underestimated the importance of heterotrophic sediment N2 ...
