Light-dark fluctuated metabolic features of diazotrophic and non-diazotrophic cyanobacteria and their coexisting bacteria

Science of The Total Environment
Cyanobacteria, the most abundant photosynthetic organisms in oceans, are tightly associated with diverse microbiota. However, the relationships between heterotrophic bacteria and cyanobacteria, particularly the diazotrophic group, are not fully understood.

Diazotrophs and Their Activity in Maize and Wheat

1998
Diazotrophs are microorganisms which, in association with plants, are capable of fixing 30–60 and even up to 150 kg of N ha−1, bringing yield increases of the crops grown of 5–15% (Maltseva et al., 1995; Govedarica et al., 1997).

Osmotolerance of diazotrophic rhizosphere bacteria

Plant and Soil, 1991
In the genus Azospirillum tolerance towards high concentrations of sodium chloride, sucrose or polyethylene glycol increased in the order A. amazonense A. lipoferum A. brasilense and A. halopraeferens. In A. brasilense and A. halopraeferens the compatible solutes trehaloseglutamate and an unknown compound were identified. A.

The rice endophytic diazotroph and PGPR

1998
The selective pressure of the rhizoplane of rice plants for colonized beneficial rhizobacteria has been investigated. The rhizobacteria were isolated from the rhizoplane of rice variety Yue Guang (with a middling disease-resistant trait) and Yue Fu (with a high yield trait).

Rice Endophytic Diazotrophic Bacteria

2010
The extension of nitrogen-fixing symbioses to cultivated rice has been a long-standing goal in the field of biological nitrogen fixation. Endophytic bacteria have been found in virtually every plant studied, where they colonize the internal tissues of their host plant and do not cause any harmful effect to their host plant.

Studies on the Diazotrophic Nature of Agrobacterium

1987
Although 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.

Genomic Manipulations of the Diazotroph Azotobacter vinelandii

2018
The 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.

Ecology and Microbiology of Symbiotic Diazotrophs

1984
Nodulation 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 ...

Across-Habitat Comparison of Diazotroph Activity in the Subarctic

Microbial Ecology, 2014
Nitrogen (N) fixation by N2-fixing bacteria (diazotrophs) is the primary N input to pristine ecosystems like boreal forests and subarctic and arctic tundra. However, the contribution by the various diazotrophs to habitat N2 fixation remains unclear.

Oxygen and the Physiology of Diazotrophic Microorganisms

1984
This 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.
