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).

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 ...

"For example, legumes, known for their nitrogen-fixing ability, benefited more from dung with a lower nitrogen-to-phosphorus ratio, such as that from European bison or horses. The study not only ...
