Sinorhizobium frediistrain USDA191 forms N-fixing nodules on the soybean (Glycine max L. Merr.) cultivars (cvs) McCall and Peking, but S. fredii strain USDA257 nodulates only cv Peking. We wondered whether specificity in this system is conditioned by

Flavonoid cues from the plant host cause symbiotic, nitrogen-fixing rhizobia to synthesize lipochitooligosaccharides (LCOs), which act as return signals to initiate the nodulation process. Rhizobium fredii strain USDA257 is known to produce four LCOs
