There are other plants that form symbiotic relationships with bacteria to fix nitrogen--such as alder trees, which form a symbiotic relationship with Frankia bacteria--but legumes are the only food crop to do so.
Black alder could be considered to be a "biological fertilizer", which improves soil nitrogen status, fixing N2 in symbiosis with Frankia in its root nodules, and increases phosphorus availability in soil by the activity of its roots and associated microbial communities [13, 14].
Frankia houses a number of nif genes but researchers failed to spot nod genes in Frankia [139].
