Researchers have identified a plant enzyme that is key to activating a nitrate uptake mechanism in response to nitrogen starvation. This finding explains how plants meet their needs in challenging ...

"We studied a large number of wheat and barley genotypes under different nitrogen supply conditions and analyzed their root architecture and nitrogen accumulation in the plants," says lead author Md.

Researchers are one step closer to understanding how some plants survive without nitrogen. Their work could eventually reduce the need for artificial fertilizer in crops such as wheat, maize, or rice.

Rising carbon dioxide levels will cause crops to become less nutritious by cutting plants’ nitrogen concentrations, according to a study published Wednesday in Trends in Plant Science, leading ...

For years, scientists have seen enhanced photosynthesis as one of the only possible bright sides of increasing levels of atmospheric carbon dioxide (CO2) -- since plants use carbon dioxide for ...
