Heterocyst differentiation constitutes a pivotal developmental process in filamentous cyanobacteria, allowing these organisms to sidestep the oxygen sensitivity of the nitrogenase enzyme. Under ...

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.

An oxygen sensor protein protects the enzymatic machinery of biological nitrogen fixation from serious damage, and its use in ...

Food productivity is dependent on the availability of fertilizer, says Utah State University biochemist Lance Seefeldt. "We need nitrogen to survive, but we can't take it in from the air," says ...

A study found that we have overestimated how much nitrogen enters natural ecosystems from the air. It has climate implications.

As nitrogen availability is often the limiting factor to growth and biomass production, nitrogen fixation is one of the most important biological processes on Earth. Now, new research has revealed ...
