Nitrogen shortage limits young tropical forest growth, slowing carbon capture that could help fight climate change.

When we think of the atmosphere and its necessity in sustaining life, we are thinking of oxygen and for plants, carbon dioxide. There is another chemical, though, a clear, odorless and tasteless gas ...

To combat this problem, scientists have been attempting to use genetic engineering to help crops control their own ...

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 ...

CO2 can stimulate plant growth, but only when enough nitrogen is available—and that key ingredient has been seriously ...

Considered natural allies against climate change due to their absorption of carbon dioxide, plants may however offer more limited help than expected. The cause: an essential ...

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

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 ...

As the Arctic Ocean loses its sea ice due to climate change, sunlight penetrates deeper into the water and encourages the growth of tiny plant-like organisms (phytoplankton). But to thrive, they need ...

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, ...

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 ...
