Recent advances in the active biomolecules involved in Rhizobia-legume symbiosis

Abstract

The mutualistic interactions between nodule-forming rhizobia and specific legume host plants involve a series of signalling molecules leading to the establishment of a strong and functional symbiosis between the two partners. The competitive ability and legume host specificity of rhizobia together with the ability of both rhizobia and legumes to release functionally divergent active molecules determines the success of symbiotic relationships. Here, recent developments in the key active biomolecules affecting legume-rhizobia symbiosis are surveyed and discussed.
