Role of lectins (and rhizobial exopolysaccharides) in legume nodulation

Curr Opin Plant Biol. 1999 Aug;2(4):320-6. doi: 10.1016/S1369-5266(99)80056-9.


The lectin recognition hypothesis proposes that plant lectins mediate specificity in the Rhizobium-legume symbiosis. Although the hypothesis was developed eight years before nod genes were identified in rhizobia and sixteen years before Nod factor was shown to be a major determinant of host specificity, experiments performed recently using transgenic lectin plants support its main tenets.
