Effect of combined nitrogen on symbiotic nitrogen fixation in pea plants [PDF]

, 1979
The nitrogen-fixing activity of the symbiotic system of Pisum sativum with Rhizobium leguminosarum is adversely affected by combined nitrogen. Both ammonium chloride and potassium nitrate, when added to the roots, lower the nitrogenase activity ...

PII protein is essential for transcriptional regulation of anf gene cluster for iron-only nitrogenase in Rhodopseudomonas palustris

Applied and Environmental Microbiology
In addition to catalyzing the biological nitrogen fixation, iron-only (Fe-only) nitrogenase is also able to reduce carbon dioxide (CO2) to formate (HCOO−) and methane (CH4).

Effects of Selected Herbicides on Growth and Nitrogen Fixing Activity of Stenotrophomonas maltophilia (Sb16) [PDF]

Polish Journal of Microbiology, 2016
A study was carried out to determine the effects of paraquat, pretilachlor and 2, 4-D on growth and nitrogen fixing activity of Stenotropho­monas maltophilia (Sb16) and pH of Jensen’s N-free medium.

Is moss-associated nitrogen fixation controlled by the same factors across shoots, species and sites?

Environmental and Experimental Botany
Biological N2 fixation performed by moss-associated cyanobacteria is among the main sources of new nitrogen (N) input in pristine subarctic ecosystems.

Classifying the metal dependence of uncharacterized nitrogenases

Frontiers in Microbiology, 2013
Nitrogenase enzymes have evolved complex iron-sulfur (Fe-S) containing cofactors that most commonly contain molybdenum (MoFe, Nif) as a heterometal but also exist as vanadium (VFe, Vnf) and heterometal independent (Fe-only, Anf) forms.

Accessory Proteins of the Nitrogenase Assembly, NifW, NifX/NafY, and NifZ, Are Essential for Diazotrophic Growth in the Nonheterocystous Cyanobacterium Leptolyngbya boryana

Frontiers in Microbiology, 2019
Since nitrogenase is extremely vulnerable to oxygen, aerobic or micro-aerobic nitrogen-fixing organisms need to create anaerobic microenvironments in the cells for diazotrophic growth, which would be one of the major barriers to express active ...

From apex to base: Uncovering spatial metabolic adaptation in Antarctic mosses

Bulletin of the Korean Chemical Society, EarlyView.
Antarctic mosses survive extreme cold, desiccation, UV exposure, and oxidative stress. We analyzed three species by separating apical, middle, and basal zones. Each zone showed distinct metabolite patterns and biological roles, revealing spatial metabolic specialization. The results suggest that whole‐plant survival depends on coordinated contributions

Enzymatic Electrosynthesis for Sustainable CO2 Conversion: Advancing Circular Carbon Economy

Carbon Energy, EarlyView.
Enzymatic electrosynthesis (EES) offers molecular precision in synthesizing value‐added products from CO2. We highlight its distinct edge over alternative enzyme‐hybrid systems and analyze electron transfer pathways. Key strategies to overcome electron transfer bottlenecks and expand product diversity are addressed, and also data‐driven approaches for ...
