Influence of ammonium and moisture on survival and nifH transcription in the diazotrophic Pseudomonas mendocina S10

open access: yesNotulae Scientia Biologicae, 2020
Nitrogen is important for crop productivity and usually added in form of urea into the soil which negatively affects the environment. It is important to utilize nitrogen fixing bacteria for improving the nitrogen content of soil in India.

Transient Ecological Niches for Diazotrophs in Upwelling Bays

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Diazotrophs, microorganisms capable of fertilizing the ocean through biological nitrogen fixation (BNF), are widespread in the oceans, including upwelling bays. However, their ability to respond to short‐lived upwelling pulses, lasting only a few days, remains poorly understood. To investigate diazotrophy across temporal scales, we analyzed 18

Faba Bean (Vicia faba L.) Nodulating Rhizobia in Panxi, China, Are Diverse at Species, Plant Growth Promoting Ability, and Symbiosis Related Gene Levels

open access: yesFrontiers in Microbiology, 2018
We isolated 65 rhizobial strains from faba bean (Vicia faba L.) from Panxi, China, studied their plant growth promoting ability with nitrogen free hydroponics, genetic diversity with clustered analysis of combined ARDRA and IGS-RFLP, and phylogeny by ...

Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean Estuary

open access: yesEnvironmental Microbiology, Volume 28, Issue 8, August 2026.
Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...

Expression of nifH genes by diazotrophic bacteria in the rhizosphere of short form Spartina alterniflora [PDF]

open access: yesFEMS Microbiology Ecology, 2003
Abstract A diverse assemblage of diazotrophic bacteria exists in the rhizosphere of the smooth cordgrass, Spartina alterniflora, but the taxa actively involved in nitrogen fixation have not been determined. In order to identify the diazotrophs that were actively expressing nifH, the gene encoding the nitrogenase iron protein, mRNA was extracted from ...

Identifikasi dan Kekerabatan Rhizobia Pohon Mangium dan Sengon Berdasarkan nodD1 dan nifH

open access: yesJurnal Ilmu Pertanian Indonesia, 2022
Rhizobia from legumes Acacia mangium (Mangium) and Paraserianthes falcataria (Sengon) have often been isolated and studied for their applications to plants, but studies on the nod and nif genes are still lacking.

Nitrogen and Phosphorus Controls on Phytoplankton Growth and Bacterioplankton Communities in Wetland Impoundments

open access: yesFreshwater Biology, Volume 71, Issue 8, August 2026.
ABSTRACT Nutrient enrichment in shallow lakes and ponds can shift systems from clear water, macrophyte dominance to turbid, phytoplankton dominance. Because the identity and threshold of the limiting nutrients vary among sites, system‐specific evidence is needed to guide water quality management. We conducted 3‐day in situ nutrient‐enrichment bioassays

Natural Variation of NAR5 Determines Nitrogenase Activity and the Yield in Soybean

open access: yesAdvanced Science, Volume 13, Issue 38, 9 July 2026.
This study identified NAR5, a gene encoding a subtilisin‐like protease, that regulates nitrogenase activity in soybean nodules. Overexpressing NAR5 delayed nodule senescence, enhancing nitrogenase activity, yield, and low‐nitrogen tolerance. The elite haplotype NAR5HapI‐1 linked to superior nitrogenase activity and greater seed weight has been ...

Marine bacterial richness increases towards higher latitudes in the eastern Indian Ocean

open access: yesLimnology and Oceanography Letters, 2018
We investigated the bacterial community structure in surface waters along a 2500 km transect in the eastern Indian Ocean. Using high throughput sequencing of the 16S rRNA gene, we measured a significant latitudinal increase in bacterial richness from 800

Soil Microbiota and Rhizosphere Dynamics: Ecological Mechanisms Driving Crop Stress Adaptation in Climate‐Smart Agriculture

open access: yesFood and Energy Security, Volume 15, Issue 4, July/August 2026.
ABSTRACT Climate change‐mediated abiotic stresses limit crop performance, and plant responses are increasingly recognized as emergent properties of the coupling between soil, plants, and microbiomes rather than inherent plant characteristics. This review synthesizes mechanistic evidence from 2020 to 2025 on how rhizosphere microbiota contribute to crop
