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 ...

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 typical day for Jieshun Lin began with a long bus ride to the greenhouses. “For 10 hours each day, I would pull up plants and wash their roots, looking carefully at each individual plant. [Up to] 10 ...

Nitrogen is essential for all life on Earth. In the global oceans, however, this element is scarce, and nitrogen availability is therefore critical for the growth of marine life. Some bacteria found ...

Freshwater and coastal waters may cover just a small portion of the planet, but they turn out to be powerful contributors to nitrogen fixation, a natural process essential to life on Earth. Subscribe ...

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 ...

NORFOLK, Va. — When most people think of lightning, they picture bright flashes in the sky or the rumble of thunder that follows. But lightning does more than put on a show during storms: it helps ...

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 ...
