All of the following statements concerning the Actinomycetes filamentous soil bacterium Frankia are correct except that Frankia:
-
- Can induce root nodules on many plant species
- Cannot fix nitrogen in the free-living state.
- Forms specialized vesicles in which the nitrogenase is protected from oxygen by a chemical barrier involving triterpene hopanoids
- Like Rhizobium, it usually infects its host plant through root hair deformation and stimulates cell proliferation in the host’s cortex
Correct Option: B
Frankia, is a nitrogen fixing mycelial bacterium which is not free living and associated symbiotically with the root nodules of several non legume plants.
