Nitrogen fixation in root nodules of alnus is brought about by Frankia.
Explanation:
- Alnus is a genus of plants that belongs to the family Betulaceae.
- It is capable of forming a symbiotic relationship with a nitrogen-fixing bacterium called Frankia.
- The bacterium invades the root hairs of Alnus and induces the formation of nodules on the roots.
- These nodules provide a specialized environment for the bacterium to fix atmospheric nitrogen into ammonia, which can then be used by the plant for its growth and development.
- Frankia is a filamentous actinomycete bacterium that is able to fix nitrogen in the absence of oxygen.
- The symbiotic relationship between Alnus and Frankia is important for the ecological balance of many ecosystems, especially in areas with poor soil quality.
