In addition to existing on their own in soil, these Gram-negative bacteria respond to flavonoids by releasing Nod factors and associate with plants such as clovers, alfalfa ? and lentils by establishing root nodules.
"Sino" was previously appended before a genus of these which was merged with a genus called Ensifer, and "Brady" is appended before a genus of slow growing ones of these. These organisms share their defining characteristic with Frankia, and mutations of the aatA protein makes them unable to metabolize dicarboxylic acids. Lodwig et al. proposed a model to explain their role in the cycling of glutamate and aspartate in their hosts and they are genetically similar to Azotobacter.  In addition to existing on their own in soil, these Gram-negative bacteria respond to flavonoids by releasing Nod factors and associate with plants such as clovers, alfalfa ? and lentils by establishing root nodules. FTP, identify these bacteria that, through their enzyme nitrogenase, form a symbiotic relationship with legumes in order to fix nitrogen.
