| Thus, we can see that nitrogen fixation is a unique process in which the soybean plant and bacteria work closely together throughout the season. |
| In addition, when Cuscuta parasitises Lupinus albus, atmospheric nitrogen fixation by the nitrogen-fixing host is severely depressed. |
| In the 1970s, purified heterocysts from this strain were used to demonstrate that they are the sites of aerobic nitrogen fixation. |
| Legumes, such as soybean, are able to capture atmospheric nitrogen and utilize it through the process of nitrogen fixation. |
| In return, the plant shelters and nourishes the bacterium inside root nodules, where nitrogen fixation occurs. |
| The nitrogen fixation process depends on a successful symbiotic relationship between a bacteria species and a host plant. |
