Phosphate modulates elemental and macromolecular composition of unicellular nitrogen‐fixing cyanobacteria

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract The C : N : P of nitrogen‐fixing cyanobacteria regulates phosphate‐limited nitrogen fixation in the ocean yet the causes and range in variation C : N : P is not well constrained. Here we quantify the C : N : P and underlying macromolecular composition of Crocosphaera.

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

Advanced Science
Symbiotic nitrogen fixation (SNF) serves as a vital process through which legumes acquire atmospheric nitrogen, directly influencing plant growth, yield, and soil fertility.

Global Carbon Investment in Terrestrial Biological Nitrogen Fixation

Global Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract Biological nitrogen (N) fixation (BNF) provides the N needed to produce proteins and other biological building blocks, helping feed humanity and mitigate climate change. Due to its high energetic cost compared to other forms of N acquisition, biotic investment in BNF indicates N limitation. Globally gridded BNF flux data provide an opportunity

Expression Map for Genes Involved in Nitrogen and Carbon Metabolism in Alfalfa Root Nodules

Molecular Plant-Microbe Interactions, 1999
During root nodule development several key genes involved in nitrogen fixation and assimilation exhibit enhanced levels of expression. However, little is known about the temporal and spatial distribution patterns of these transcripts.

Decoding stress resilience in soybean: Regulatory networks and precision breeding under climate change

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2838-2868, August 2026.
This review covers recent progress in the understanding of stress‐responsive regulatory networks in soybean and highlights emerging genomic and breeding strategies. Integrating molecular insights and precision breeding will help to accelerate the development of climate‐resilient soybean cultivars.

A nitrogenase-like enzyme is involved in the novel anaerobic assimilation pathway of a sulfonate, isethionate, in the photosynthetic bacterium Rhodobacter capsulatus

mSphere
Prokaryotes contribute to the global sulfur cycle by using diverse sulfur compounds as sulfur sources or electron acceptors. In this study, we report that a nitrogenase-like enzyme (NFL) and a radical SAM enzyme (RSE) are involved in the novel anaerobic ...

A Systematic DFT Approach for Studying Mechanisms of Redox Active Enzymes

Frontiers in Chemistry, 2018
When DFT has been applied to study mechanisms of redox processes a common procedure has been to study the results for many different functionals. For redox reactions involving the first row transition metals, this approach has given very different ...

Conserved symbiosis‐associated genes in the cycad Encephalartos natalensis suggest co‐option for cyanobacterial symbiosis

New Phytologist, Volume 251, Issue 4, Page 2168-2185, August 2026.
The heterocyst‐rich Encephalartos natalensis cyanobacterial zone in coralloid root suggests co‐option of conserved symbiosis‐associated genes. This figure was created in BioRender (BioRender.com/https://BioRender.com/n3qveqc). Summary Plant‐cyanobacterial symbioses have evolved independently at least four times across land plants, yet their underlying ...

Ecological niches and biogeography of nitrogen‐fixing plants in Europe

Plant Biology, Volume 28, Issue 5, Page 1349-1360, August 2026.
Despite sharing N fixation as a common trait, European legume and actinorhizal plant lineages occupy strikingly divergent ecological niches shaped by their evolutionary histories and physiological adaptations. Advanced symbiont control allows IRLC legumes to expand into northern, mesic regions, while non‐IRLC legumes are more common in Mediterranean ...

Molecular recognition in plant root endosymbiosis

The Plant Journal, Volume 127, Issue 3, August 2026.
SUMMARY Root endosymbiosis is one of the most intimate types of plant–microbe interactions in which a symbiont is hosted within a living plant cell. In this symbiosis, nitrogen‐fixing bacteria and arbuscular mycorrhizal fungi support plant nutrient provisioning in exchange for carbohydrates and lipids.
