The marine nitrogen cycle is crucial to sustaining ocean productivity, with biological nitrogen fixation representing a primary mechanism by which inert atmospheric nitrogen is converted into ...

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 ...

Nitrogen is vital for all known life. Yet most nitrogen on Earth is in the atmosphere as di-nitrogen gas, which many organisms can’t use. Fortunately, there are microbes that can tap into this ...

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 ...

Nitrogen fixation in boreal forests is vital for sustaining ecosystem productivity in environments where soil nitrogen is limited. Moss-cyanobacteria associations, commonly found in species such as ...

Most organisms require nitrogen to produce biological molecules, such as nucleotides and amino acids, but until recently, only prokaryotes were known to fix nitrogen from the atmosphere. “It’s a very ...

Scientists shed light on an unexpected partnership: A marine diatom and a bacterium that can account for a large share of nitrogen fixation in vast regions of the ocean. This symbiosis likely plays a ...

A new evaluation of biological nitrogen fixation for inland and coastal waters concludes that these habitats are an overlooked but important source of fixation globally. Robinson Fulweiler and ...

Researchers at University of Tsukuba have uncovered a master transcriptional regulator that controls rhizobial symbiosis ...

Forests, grasslands, and other natural areas around the world have access to about a quarter less nitrogen than previously estimated, according to a new study published in Nature. Coauthored by Sarah ...

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, ...
