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 ...

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 new accounting of nitrogen pollution in the Mississippi-Atchafalaya River Basin (MARB) reveals a significant decline in recent decades, suggesting positive momentum for water quality goals in local ...

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 ...

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 ...

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 ...

If corn was ever jealous of soybean’s relationship with nitrogen-fixing bacteria, advancements in gene editing could one day even the playing field. A recent study from the ...

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 ...

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

Researchers demonstrate that the plant hormone gibberellin (GA) is essential for the formation and maturation of nitrogen-fixing root nodules in legumes and can also increase nodule size. Researchers ...

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, ...
