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 ...

Heterologous Expression of the Nitrogen-Fixing Gene Cluster from Paenibacillus polymyxa in Bacillus subtilis

Microorganisms
Microbially mediated biological nitrogen fixation is pivotal to sustainable agricultural development. However, optimizing nitrogenase activity in native biological nitrogen-fixing bacteria has been hindered by the complexities of genetic manipulation ...

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.

A Proposed Complete‐Cycle Mechanism for Conversion of N2 to NH3 by Mo‐Nitrogenase

ChemBioChem, Volume 27, Issue 14, 29 July 2026.
How does the enzyme nitrogenase convert N2 to NH3 under ambient conditions? Here I describe a proposed complete cycle of the chemical mechanism, with computed energy profiles and kinetic barriers for a sequence of 31 reaction steps, encompassing 40 intermediates. How does the enzyme nitrogenase convert N2 to NH3 under ambient conditions?

The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

mLife
Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.
