Nitrogenase (nifH) gene expression in diazotrophic cyanobacteria in the Tropical North Atlantic in response to nutrient amendments

Frontiers in Microbiology, 2012
The Tropical North Atlantic (TNAtl) plays a critical role in the marine nitrogen cycle, as it supports high rates of biological nitrogen (N2) fixation, yet it is unclear whether this process is limited by the availability of iron (Fe), phosphate (P) or ...

Calcium and Nitrogen Availability Controls Root Exudation in Hydroponically Cultured Barley

Plant, Cell &Environment, EarlyView.
ABSTRACT Root exudation is a key component of plant‐rhizosphere interactome. It is increasingly evident that root exudates influence rhizospheric microbial communities and in turn can benefit plants through improved resource allocation. However, how suboptimal nutrient availability relates to control of root exudation is poorly understood.

Multiomic Approaches Reveal Hormonal Modulation and Nitrogen Uptake and Assimilation in the Initial Growth of Maize Inoculated with Herbaspirillum seropedicae

Plants, 2022
Herbaspirillum seropedicae is an endophytic bacterium that can fix nitrogen and synthesize phytohormones, which can lead to a plant growth-promoting effect when used as a microbial inoculant.

DNA Methylation Shapes Seed‐Borne Microbiome and Proteome Responses During Early Maize‐Beneficial Bacteria Interactions

Plant, Cell &Environment, EarlyView.
ABSTRACT Microorganism and plant interactions are crucial for development and environmental adaptation. Plant growth promoting bacteria enhance agricultural productivity in a sustainable manner, while epigenetic modifications such as DNA methylation regulate gene expression and adaptive responses.

The shifts of diazotrophic communities in spring and summer associated with coral Galaxea astreata, Pavona decussata and Porites lutea

Frontiers in Microbiology, 2016
The coral holobiont often resides in oligotrophic waters; both coral cells and their symbiotic dinoflagellates possess ammonium assimilation enzymes and potentially benefit from the nitrogen fixation of coral-associated diazotrophs. However, the seasonal

Marine Phytoplankton Extremes and Compound Extreme Events Have the Potential to Be Predicted Multiple Months in Advance

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Global marine primary producers, phytoplankton, are the base of the marine food web and vary on short timescales, characterized by seasonal blooms. There is growing concern about the occurrence of short‐term extreme events in phytoplankton abundance, which may impact higher trophic levels and economically‐important species.

Linking Plant and Microbial Traits to Soil Carbon for Reliable and Resilient Bioenergy Systems

GCB Bioenergy, Volume 18, Issue 7, July 2026.
Plant–microbe–soil interactions supporting productivity and soil carbon storage in bioenergy systems. Plants supply organic inputs that sustain microbial communities driving nutrient cycling, carbon stabilization, and soil aggregation. These interactions enhance soil structure and nutrient retention, supporting both biomass productivity and broader ...

Effects of Water Column Mixing and Stratification on Planktonic Primary Production and Dinitrogen Fixation on a Northern Red Sea Coral Reef

Frontiers in Microbiology, 2018
The northern Red Sea experiences strong annual differences in environmental conditions due to its relative high-latitude location for coral reefs. This allows the study of regulatory effects by key environmental parameters (i.e., temperature, inorganic ...

Ocean warming indirectly affects seagrass performance through effects on sediment microbial communities

New Phytologist, Volume 251, Issue 1, Page 191-206, July 2026.
Summary Belowground microbes are increasingly recognised as mediators of plant responses to stress, but it remains unclear whether the thermal histories of marine plants and their associated belowground microbes influence plant performance under ocean warming.
