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 ...

by far the most important nitrogen-fixing symbiotic associations are the relationships between legumes and Rhizobium and Bradyrhizobium bacteria. Important legumes used in agricultural systems ...

UCYN-A live in a symbiotic relationship with a closely related group of marine algae, B. bigelowii, in areas of the open ocean that are often low in nutrients. Most nitrogen-fixing bacteria have ...

Plants with root nodules, for example, secrete compounds such as flavonoids when nitrates are scarce in the soil, helping to activate signaling pathways in nitrogen-fixing bacteria that then ...

Most of the symbiotic associations are very specific ... serve as a signal to certain species of Rhizobium, which are nitrogen-fixing bacteria. This signal attracts the bacteria to the roots ...

Autumn olive engages in a symbiotic relationship with Frankia bacteria in root nodules, the location where nitrogen fixation occurs. Previous research has demonstrated that autumn olive is capable of ...

While most vegetation types must extract most of their nutrients from fertile soil, mesquites and similar plants receive additional nitrogen from symbiotic bacteria, which enzymatically fix ...

How did we get to a place where we think of soil as dirt? Soils are buzzing with life, criss-crossed with a hard-to-fathom ...

The U.S. Department of Energy granted Dr. Jean-Michel Ané and his colleagues $5.5 million to study systems to cut synthetic ...

For years, attempts have therefore been made to transfer the natural nitrogen fixation in bacteria and archaea to crops. The enzyme nitrogenase is responsible for the binding of nitrogen.

Soybeans fix nitrogen, everyone knows that, but did you know soil bacteria are key partners in the process? Rhizobia, the soil bacteria in question, form a symbiotic relationship with the soybeans ...

That means their nitrogen came from symbiotic bacteria. But in the older and extinct cycad fossils, that nitrogen signature was absent. What is less clear is how nitrogen fixation helped the surviving ...
