All known life forms require nitrogen. However, more than 70% of all nitrogen on Earth occurs as inert, triple-bonded dinitrogen gas in the atmosphere, which is generally biologically unavailable. A ...

A research team has discovered how the 'Shethna protein II' protects the nitrogen-fixing enzyme nitrogenase from damage. The oxygen sensor protein could help to make nitrogenase usable in ...

Climate change also alters nitrogen in soils and plants, shaping food quality, water safety, and pollution risks worldwide.

Red alder is a nitrogen-fixing plant species. Photo by Steven Perakis. CORVALLIS, Ore. – A new study indicates that forests, prairies and other natural areas around the globe acquire less nitrogen ...

A new research initiative led by associate professor of bacteriology Betül Kaçar is positioned to transform agriculture and address some of the world’s most pressing ecological and economic challenges ...

The uneven distribution of biological nitrogen fixation in terrestrial ecosystems has yet to be explained. Latitudinal gradients in temperature and phosphorus may hold the answer. Like the ancient ...

Global inventory reveals nitrogen is in shorter supply than previously thought in natural areas, which could limit carbon storage in plants and soils. “Outside of some tropical forests and drylands, ...

CO2 can stimulate plant growth, but only when enough nitrogen is available—and that key ingredient has been seriously miscalculated. A new study finds that natural nitrogen fixation has been ...
