Biogeography of diazotrophic bacteria in soils

World Journal of Microbiology and Biotechnology, 2010
This study evaluated diazotrophic bacterial diversity of soils from four different sites in South and North America. Approximately one hundred and thirty-nine thousand partial sequences of the small subunit of the bacterial ribosomal RNA gene generated for a previous study were used for this work.

Interactions Between Diazotrophs and Grasses

1997
Molecular 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.

Nitrogen Losses from Diazotrophic Lichens

1985
Nitrogen loss from lichens has received little attention in the past and has only relatively recently become the subject of study by a few groups. Early investigations were concerned with the total input of nitrogen into an ecosystem and naturally follow the realisation that since a number of lichens contain a member of the Cyanophyceae they might ...

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.

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).

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 ...

Differential proteomic expression of himalayan psychrotrophic diazotroph Pseudomonas palleroniana N26 under low temperature diazotrophic conditions.

Cryo letters, 2015
In low temperature nitrogen-deficient ecosystems, native microorganisms must possess adaptive mechanisms to cope with environmental stress as well as nitrogen (N) starvation-like conditions. However, moderate information is available about the cold adapted diazotrophs and diazotrophy.The aim of this study was to examine the proteomic response(s) of ...
