The legume-rhizobia relationship in the Mediterranean basin

Howieson J.G., O'Hara G.W., Loi A.

To effectively harness the value of symbiotic N-fixation we need to understand G2 x E, where G refers to the genotypes of both legume and microsymbiont, and E the edaphic environment in which the symbiosis is to function. In the Mediterranean basin there is strong evidence that despite co-evolution of legumes and rhizobia, the relationship is not always optimal. Several research options are presented to improve N-fixation depending on the nature of the limitation to legume or rhizobial performance.
