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

mLife, EarlyView.
Abstract 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.

Iterative Genome Engineering Platform Enables Efficient Sucrose Biosynthesis From CO2 in Photosynthetic Synechococcus elongatus UTEX 2973

Plant Biotechnology Journal, EarlyView.
ABSTRACT The single crossover occurring via homologous recombination is a common phenomenon existing among microbes like Escherichia coli, Bacillus subtilis, Vibrio natriegens, Gluconobacter oxydans and most cyanobacteria species, threatening the stability of engineered strains and challenging iterative genetic engineering. Among them, we take the fast‐

Functional Nitrogenase Cofactor Maturase NifB in Mitochondria and Chloroplasts of Nicotiana benthamiana

mBio, 2022
Engineering plants to synthesize nitrogenase and assimilate atmospheric N2 will reduce crop dependency on industrial N fertilizers. This technology can be achieved by expressing prokaryotic nitrogen fixation gene products for the assembly of a functional

Mutagenic Survey of Key Residues of NifB Involved in Radical SAM‐Dependent Nitrogenase Cofactor Assembly

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
NifB uses an RS–K1–K2 triad to assemble the L‐cluster, a [Fe8S9C] precursor of the nitrogenase cofactor. The RS module cleaves SAM to form the 5′‐dA radical, K1 serves structural/SAM‐sensing roles, and K2 drives radical‐dependent fusion with K1. SAM‐anchoring residues link SAM binding to cluster fusion, while termini and surface residues regulate ...

Comparison of five bacterial strains producing siderophores with ability to chelate iron under alkaline conditions

AMB Express, 2019
Iron deficiency is one of the main causes of chlorosis in plants, which leads to losses in field crops quality and yield. The use of synthetic chelates to prevent or correct iron-deficiency is not satisfactory mainly due to their poor biodegradability ...

Inoculation With Azospirillum brasilense and Bacillus amyloliquefaciens Enhances Tomato Resilience to Severe Water Deficit: A Comprehensive Morpho‐Physiological and Biochemical Analysis

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Inoculation with Azospirillum brasilense and Bacillus amyloliquefaciens significantly enhances tomato tolerance to severe water deficit. This strategy boosts agronomic performance, strengthens antioxidant defences and regulates secondary metabolites, providing a sustainable agricultural approach to combat water scarcity and climate change impacts ...
