| 1. | Not all legume species can develop a symbiosis with rhizobia to use atmospheric nitrogen.
|
| 2. | Inoculation with rhizobia tends to increase yield.
|
| 3. | Within the root nodules, rhizobia fix atmospheric nitrogen into ammonia using the nitrogenase enzyme.
|
| 4. | There are several types of rhizobia, and some have a high degree of host specificity.
|
| 5. | During his career Bisseling has done research on the symbiosis between root nodules and rhizobia bacteria.
|
| 6. | The rhizobia and their hosts must be able to recognize each other for nodule formation to commence.
|
| 7. | After production of cellulose fibrils, a Homologues of this protein can be found in other rhizobia.
|
| 8. | A classic example of mutualism is the interaction between rhizobia soil bacteria and legumes ( Fabaceae ).
|
| 9. | Rhizobia is the group of soil bacteria that infect the roots of legumes to form root nodules .
|
| 10. | The rhizobia, which fix nitrogen and are symbiotic with plant roots, appear in several different families.
