All of the following statements concerning the actinomycetous filamentous soil bacterium Frankia are correct except that Frankia
Can induce root nodules on many plant species
Can fix nitrogen in the free-living state
Like Rhizobium, it usually infects its host plant through root hair deformation and stimulates cell proliferation in the host's cortex
Forms specialized vesicles in which the nitrogenase is protected from oxygen by a chemical barrier involving triterpene hopanoids

Frankia is a bacterium which grows in a symbiotic association with the roots of non-leguminous plants-xA0- It can fix atmospheric nitrogen- It cannot fix nitrogen in free-living state-So- the correct option is -apos-Can fix nitrogen in free-living state-apos-

Frankia is a bacterium which grows in a symbiotic association with the roots of non-leguminous plants. It can fix atmospheric nitrogen. It cannot fix nitrogen in free-living state.So, the correct option is 'Can fix nitrogen in free-living state'.

Frankia is a bacterium which grows in a symbiotic association with the roots of non-leguminous plants. It can fix atmospheric nitrogen. It cannot fix nitrogen in free-living state.
So, the correct option is 'Can fix nitrogen in free-living state'.
