Frontiers in Marine Science, 2022 The apparently obligate symbiosis between the diazotroph Candidatus Atelocyanobacterium thalassa (UCYN-A) and its haptophyte host, Braarudosphaera bigelowii, has recently been found to fix dinitrogen (N2) in polar waters at rates (per cell) comparable to

Molecular Microbiology, EarlyView.The glycosyltransferase All4160 is regulated by the reversible phosphorylation of Ser74. The kinase Alr3423 phosphorylates and inactivates All4160, while the SpoIIE‐like phosphatase HenR restores its activity through dephosphorylation. A nonphosphorylatable variant of All4160 bypasses the need for HenR, which demonstrates that a phosphorylation ...

Dinitrogen fixation by Cyanobacteria
International Journal of Environmental SciencesNitrogen is the most abundant element in the Earth’s atmosphere in the form of di-nitrogen gas; it is not assimilable by plants or any other organism as such. Biological Nitrogen Fixation (BNF) is carried out by a specialized group of prokaryotes, like Cyanobacteria.

Niche construction by non‐diazotrophs for N2 fixers in the eastern tropical North Atlantic Ocean
Geophysical Research Letters, 2017 Diazotrophic dinitrogen (N2) fixation contributes ~76% to “new” nitrogen inputs to the sunlit open ocean, but environmental factors determining N2 fixation rates are not well constrained.

Di-nitrogen fixation at the early and late growth stages of soybean
Acta Scientiarum. Agronomy, 2018 Soybean derives a significant portion of the required nitrogen (N) from the symbiosis with rhizobia bacteria. However, information on the available genetic variation for N2 fixation capacity in different growth stages of soybean is limited.

Investigation of the Role of Phosphorus in Symbiotic Dinitrogen Fixation [PDF]
Plant Physiology, 1987 The interactive effects of phosphorus supply and combined nitrogen (nitrate) on dry matter and nitrogen accumulation by nodulated soybean (Glycine max L. Merr.) plants, and the relative effects of phosphorus supply on nodule number, mass, and function in comparison to host plant growth were used to investigate the role of phosphorus in symbiotic ...

Preparation of Rocksalt‐Type Semiconductor Ca2TaN3 via Hot Isostatic Pressing
Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 9, 3 June 2026.The rocksalt‐type nitride Ca2TaN3 was prepared via hot isostatic pressing at 1400°C and 150 MPa of static dinitrogen pressure. The yellow compound is a semiconductor with a bandgap of 2.5 eV. The rocksalt‐type double nitride Ca2TaN3 was synthesized via hot isostatic pressing (HIP) at 1400°C and 150 MPa static dinitrogen pressure from Ca3N2 and Ta3N5 ...
