Ecology and Microbiology of Symbiotic Diazotrophs
1984Nodulation of legumes by rhizobia occurs in a series of steps which include: (1) rhizobial growth in the plant rhizosphere; (2) attachment of the rhizobia to roothairs of the legume; (3) rhizobial induced root-hair curling; (4) infection thread formation within the root hairs (5) growth of the ...

Genomic Manipulations of the Diazotroph Azotobacter vinelandii
2018The biological reduction of nitrogen gas to ammonia is limited to a select group of nitrogen-fixing prokaryotes. While nitrogenase is the catalyst of nitrogen fixation in these biological systems, a consortium of additional gene products is required for the synthesis, activation, and catalytic competency of this oxygen-sensitive metalloenzyme.

Studies on the Diazotrophic Nature of Agrobacterium
1987Although Agrobacterium and Rhizobium are known to be closely related (1) the former is always considered to be a plant pathogen. As a result, no investigation has ever been carried out to see if any Agrobacterium strains have an inherent ability to fix nitrogen either in the free-living condition or in crown galls produced by the bacterium.

Evaluation of fly ash as a carrier for diazotrophs and phosphobacteria
Bioresource Technology, 2004Fly ash and its different combinations with soil (w/w) were tested to explore its possible use as a potential carrier for diazotrophs and phosphobacteria. Azotobacter chroococcum, Azospirillum brasilense and Bacillus circulans showed their maximum viability in fly ash alone whereas Pseudomonas striata proliferated most in soil:fly ash (1:1) combination.

Oxygen and the Physiology of Diazotrophic Microorganisms
1984This synthesis paper discusses some aspects of O2-related problems using representative examples from recent literature seen by the author up to June 1983. A large proportion of diazotrophic microorganisms require O2 as the terminal electron acceptor for energetic pathways; these are the most energetically efficient.

Interactions Between Diazotrophs and Grasses
1997Molecular phylogenetic studies based on comparative sequence analysis of genes or protein sequences has gained increasing importance in understanding evolutionary relationships of organisms. Moreover, these techniques allowed an insight in development of intimate interactions between organisms in some cases.

Scripting a new dialogue between diazotrophs and crops
Trends in MicrobiologyDiazotrophs are bacteria and archaea that can reduce atmospheric dinitrogen (N2) into ammonium. Plant-diazotroph interactions have been explored for over a century as a nitrogen (N) source for crops to improve agricultural productivity and sustainability. This scientific quest has generated much information about the molecular mechanisms underlying the
