NifH- Harboring Bacterial Community Composition Across an Alaskan Permafrost Thaw Gradient

Frontiers in Microbiology, 2016
Since nitrogen (N) is often limiting in permafrost soils, we investigated the N2-fixing genetic potential and the inferred taxa harboring those genes by sequencing nifH gene fragments in samples taken along a permafrost thaw gradient in an Alaskan boreal

Plant Growth Promotion Diversity in Switchgrass-Colonizing, Diazotrophic Endophytes

Frontiers in Microbiology, 2021
Endophytic nitrogen-fixing (diazotrophic) bacteria are essential members of the microbiome of switchgrass (Panicum virgatum), considered to be an important commodity crop in bioenergy production.

Influence of the Mississippi River plume on diazotroph distributions in the northern Gulf of Mexico during summer 2011 [PDF]

, 2012
textIn the subtropical oligotrophic ocean, nitrogen fixation is an important source of new nitrogen (N) for supporting biological production. Previous studies have found that nitrogen-fixing Diatom-Diazotroph Associations (DDAs) are in high abundance in ...

Characterization of diazotrophic growth-promoting rhizobacteria isolated from ginger root soil as antagonists against Ralstonia solanacearum

Biotechnology & Biotechnological Equipment, 2018
Bacterial wilt caused by Ralstonia solanacearum (RS) has become one of the most destructive plant diseases in agricultural crops. Obtaining effective strains with disease control activity is an urgent prerequisite for biological control efficiency.

Observed and modeled diazotroph nifH abundances in the global ocean

, 2019
We supplemented the dataset presented in Luo et al. (2012) "Database of diazotrophs in global ocean: abundance, biomass and nitrogen fixation rates" with measurements of nifH genes using qPCR from 17 additional publications.

Diversity of the Bacterial Microbiome in the Roots of Four Saccharum Species: S. spontaneum, S. robustum, S. barberi, and S. officinarum

Frontiers in Microbiology, 2018
Endophytic bacteria are nearly ubiquitously present in the internal tissues of plants, and some endophytes can promote plant growth. In this study, we sampled the roots of four ancestral species of sugarcane (two genotypes per species) and two sugarcane ...

Transcriptional and Proteomic Choreography Under Phosphorus Deficiency and Re-supply in the N2 Fixing Cyanobacterium Trichodesmium erythraeum

Frontiers in Microbiology, 2019
The N2 fixing cyanobacterium Trichodesmium is a critically important organism in oligotrophic marine ecosystems, supplying “new” nitrogen (N) to the otherwise N-poor tropical and subtropical regions where it occurs.

Phyllosphere of Cotton as a Habitat for Diazotrophic Microorganisms [PDF]

Applied and Environmental Microbiology, 1984
Positive nitrogenase activities ranging from 0.18 to 0.78 nmol of C 2 H 4 cm −2 h −1 were detected on the leaf surfaces of different varieties of cotton ( Gossypium hirsutum L. and G. herbaceum L.)

Mesozooplankton Graze on Cyanobacteria in the Amazon River Plume and Western Tropical North Atlantic

Frontiers in Microbiology, 2017
Diazotrophic cyanobacteria, those capable of fixing di-nitrogen (N2), are considered one of the major sources of new nitrogen (N) in the oligotrophic tropical ocean, but direct incorporation of diazotrophic N into food webs has not been fully examined ...
