In return, the bacteria fix nitrogen for the plant. Another example of the intricate relationship between the rhizobia and the host legume is the production of leghemoglobin (Appleby 1984).

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 ...

And, if you’re not interested in plants or Mars, there are some other interesting ramifications of nitrogen-fixing as well.

Atmospheric nitrogen must first be converted, or “fixed,” into a form that can be used by plants, often as ammonia. There are only two ways of fixing nitrogen, one industrial and one biological. To ...

For example, root exudates from legume plants (e.g., peas, clover, soybeans) serve as a signal to certain species of Rhizobium, which are nitrogen-fixing bacteria. This signal attracts the ...

only prokaryotes were known to fix nitrogen from the atmosphere. “It’s a very interesting paper,” said Verena Kreichbaumer, a plant cell biologist at Oxford Brookes University who was not involved in ...
