Dancing to a different tune, can we switch from chemical to biological nitrogen fixation for sustainable food security? [PDF]
PLoS Biol, 2023 Our current food production systems are unsustainable, driven in part through the application of chemically fixed nitrogen. We need alternatives to empower farmers to maximise their productivity sustainably.

Biological Nitrogen Fixation and Nitrogen Accumulation in Peatlands [PDF]
Frontiers in Earth Science, 2022 Peatlands cover about 3% of the Earth’s surface and are regarded as a vital carbon (C) pool and sink. The formation of peatland is supported by continuously supplied nitrogen (N) but the sources of this N remain unclear.

Revisiting Biological Nitrogen Fixation Dynamics in Soybeans [PDF]
Frontiers in Plant Science, 2021 Biological nitrogen (N) fixation is the most relevant process in soybeans (Glycine max L.) to satisfy plant N demand and sustain seed protein formation.

Depth-dependent variability of biological nitrogen fixation and diazotrophic communities in mangrove sediments [PDF]
Microbiome, 2021 Background Nitrogen-fixing prokaryotes (diazotrophs) contribute substantially to nitrogen input in mangrove sediments, and their structure and nitrogen fixation rate (NFR) are significantly controlled by environmental conditions.

Assessment of the impacts of biological nitrogen fixation structural uncertainty in CMIP6 earth system models [PDF]
Biogeosciences, 2022 Biological nitrogen fixation is the main source of new nitrogen into natural terrestrial ecosystems and consequently in the nitrogen cycle in many earth system models.

Molybdenum Nanofertilizer Boosts Biological Nitrogen Fixation and Yield of Soybean through Delaying Nodule Senescence and Nutrition Enhancement. [PDF]
ACS Nano, 2023 Soybean (Glycine max) is a crop of global significance and has low reliance on N fertilizers due to its biological nitrogen fixation (BNF) capacity, which harvests ambient N2 as a critical ecosystem service.

Biological nitrogen fixation in theory, practice, and reality: a perspective on the molybdenum nitrogenase system. [PDF]
FEBS Lett, 2023 Nitrogenase is the sole enzyme responsible for the ATP‐dependent conversion of atmospheric dinitrogen into the bioavailable form of ammonia (NH3), making this protein essential for the maintenance of the nitrogen cycle and thus life itself.

Genetic modification of flavone biosynthesis in rice enhances biofilm formation of soil diazotrophic bacteria and biological nitrogen fixation. [PDF]
Plant Biotechnol J, 2022 Summary Improving biological nitrogen fixation (BNF) in cereal crops is a long‐sought objective; however, no successful modification of cereal crops showing increased BNF has been reported.

Nutrient regulation of biological nitrogen fixation across the tropical western North Pacific. [PDF]
Sci Adv, 2022 Nitrogen fixation is critical for the biological productivity of the ocean, but clear mechanistic controls on this process remain elusive. Here, we investigate the abundance, activity, and drivers of nitrogen-fixing diazotrophs across the tropical ...
