Question

Is Frankia, a symbiotic bacteria?

Answer 1

Frankia :

1. Similar to the Rhizobium bacteria found in the root nodules of legumes in the Fabaceae family, Frankia is a species of nitrogen-fixing bacteria that live in symbiosis with actinorhizal plants. Frankia is also responsible for the formation of root nodules.
2. The majority of Frankia strains are unique to specific plant species.
3. The bacteria are filamentous and use the enzyme nitrogenase to convert atmospheric nitrogen to ammonia, a process known as nitrogen fixation. They do this by dwelling in actinorhizal plants' root nodules.
4. The bacteria can meet the majority, if not all, of the host plant's nitrogen needs. As a result, actinorhizal plants colonize and frequently thrive in low-nutrient soils.
