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

open access: yesFrontiers 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

open access: yesFrontiers 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.

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

open access: yesBiotechnology & 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.

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

open access: yesFrontiers 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

open access: yesFrontiers in Microbiology, 2019
The N2 fixing cyanobacterium Trichodesmium is a critically important organism in oligotrophic marine ecosystems, supplying β€œnew” nitrogen (N) to the otherwise N-poor tropical and subtropical regions where it occurs.

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

open access: yesApplied and Environmental Microbiology, 1984
Positive nitrogenase activities ranging from 0.18 to 0.78 nmol of C 2 H 4 cm βˆ’2 h βˆ’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

open access: yesFrontiers 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 ...

Phyllosphere Exudates Select for Distinct Microbiome Members in Sorghum Epicuticular Wax and Aerial Root Mucilage

open access: yesPhytobiomes Journal, 2023
Phyllosphere exudates create specialized microhabitats that shape microbial community diversity. We explored the microbiome associated with two sorghum phyllosphere exudates, the epicuticular wax and aerial root mucilage.

Phosphorus limits the growth of bacterial and eukaryotic primary producers in recently deglaciated High Arctic soils

open access: yesOikos, EarlyView.
Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.

Observed and modeled diazotroph nifH abundances in the global ocean

open access: yes, 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.
