The bacterium_____belonging to group actinomycetes, produces `N_(2)-`fixing nodules on the roots of non-leguminous plants (e.g., Alnus)

Microbe producing nitrogen fixing nodule on the roots of non-leguminous plant is -

In nodules on the roots of leguminous plants, nitrogen is fixed by:

nitrogen fixing nodules on the roots of non leguminous plant Alnus harbours the microbe

Root nodules in leguminous plants:

Root nodules in leguminous plants:

Biofertilizer present in root nodules of non-leguminous plants is

We find that Rhizobium forms nodules on the roots of leguminous plants. Also, Frankia another microbe forms nitrogen fixing nodules on the roots of non-leguminous plants Alnus. What kind of relationship of observed between mycorrhiza and pine trees?
