Nitrogen‐Starved Wheat: A Multi‐Omics Perspective From Epigenome Regulation to Grain Quality

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
This review establishes epigenetic regulation, specifically H3K27ac and H3K27me3 dynamics at nitrogen transporter, assimilation, and storage protein loci, as a principal determinant of cultivar‐specific nitrogen use efficiency in hexaploid wheat, independent of DNA sequence variation, and identifies the rhizosphere microbiome as an integral but ...

Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress

Ecological Research, Volume 41, Issue 5, September 2026.
This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

Potential diazotroph communities of Cordia dodecandra phyllosphere endophytes in agroforestry systems

Botan‪ical Sciences
Background: Endophytic bacteria in the phyllosphere play a crucial role in plant growth and health. The microbiota of Cordia dodecandra, a Mesoamerican native species, may include diazotrophic bacteria.

Temporal changes in the diazotrophic bacterial communities associated with Caribbean sponges Ircinia stroblina and Mycale laxissima

Frontiers in Microbiology, 2014
Sponges that harbor microalgal or cyanobacterial symbionts may benefit from photosynthetically derived carbohydrates, which are rich in carbon but devoid of nitrogen, and may therefore encounter nitrogen limitation.

Spatiotemporal Regulation of N2 Fixation and Photosynthesis in Trichodesmium: New Insights From mRNA CARD‐FISH and nanoSIMS

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Examining the coordination of the O2‐sensitive N2 fixation process with photosynthesis at single‐cell level in the filamentous Trichodesmium, we find spatio‐temporal separation of N2 fixation and photosynthesis at gene expression and fixation level as well as indications for rapid intercellular transport followed by co‐localized storage of C and N ...

Spatial Variability in Recent Phototroph Production in a Large, Fluvial Lake Driven by Local Land‐Use Changes (St. Lawrence River, Canada)

Freshwater Biology, Volume 71, Issue 9, September 2026.
ABSTRACT Increases in lake production and the abundance of cyanobacteria have been reported in many temperate freshwater systems, with their rise typically attributed to elevated nutrient influx or climate change. On the St. Lawrence River (SLR), recent evidence suggests that cyanobacterial abundances have increased since ca. 2000, although the precise

Rehabilitation of Mining Sites Using Diazotrophic Bacteria and Gramineous Associations [PDF]

Degradation of mining sites resulting from deep and irreversible human action is a serious environmental problem. So, to rehabilitate mining sites, we studied the ability of diazotrophic bacteria to improve plant growth. Firstly, we isolated diazotrophic

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, Volume 5, Issue 4, August 2026.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Transient Ecological Niches for Diazotrophs in Upwelling Bays

Journal 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

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

Freshwater 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
