Abstract The peanut-rhizobia interaction: diversity in the peanut nodulating rhizobial population of Córdoba, Argentina, and role of the bacterial molecules Peanut is an important crop all over the world. More than 90% of the Argentinian peanut production is concentrated in the province of Cordoba. In the course of a project aimed to examine the diversity of peanut nodulating rhizobia, a collection of 39 isolates, obtained from nodules or from soil samples collected in Cordoba, was charactrized phenotipically and genotipically. Compared with other symbiotic association, the information on the peanut-rhizobia interaction is rather limited. Thus the second goal of our laboratory is to gain information on the symbiotic signallin compounds that are involved in the events that lead to nodule formation.
