Nitrogen fixation in root nodules of Alnus is brought about by

A

Bradyrhizobium

B

Clostridium

C

Frankia

D

Azorhizobium

Text Solution

Verified by Experts

The correct Answer is:
C
Nitrogen is the most critical element. Certain non-leguminous plants also form nodules to fix nitrogen. The best known example in temperate region is alder (Alnus sp). The bacteria involved in nodule formation is an Actinomycetes the Frankia. Clostridium is anaerobic, saprotrophic free-living nitrogen fixing bacteria.
Bradyrhizobium sp are symbiont in plants of paraspania and soyabean.
the Azorhizobium forms both stem and root nodules in sesbania (aquatic plant).
