The leguminous crop Arachis hypogaea L. (peanut) is important for providing food directly to human subsistence and many other food products. It is generally accepted that peanut is originally from where it was widely cultivated in Pre-Columbian times, and then was disseminated to tropical and subtropical regions where it throve and became an important crop. The dissemination of the crop resulted in peanut plants establishing a symbiotic nitrogen-fixing relationship with a wide diversity of indigenous soil bacteria, well adapted to local edapho-ecological conditions. We present in this review, advances on the molecular basis for the crack-entry infection process involved in the peanut-rhizobia interaction, the diversity of bacteria associated with peanut nodules, and the effect of abiotic and biotic stresses affecting this interaction.
