“Background Sinorhizobium meliloti is a soil bacterium that must survive and proliferate in various adverse conditions. S. meliloti is also able to establish a symbiotic partnership with Medicago sativa leading to the formation of nodules. In nodules, the bacterium differentiates in bacteroids and fixes atmospheric nitrogen. Within the soil and during nodulation, S. meliloti copes with various stresses imposed by the environment [1] or by plant responses to bacterial invasion [2, 3]. While nodulation is a close association between plant and S. meliloti, bacteria are initially recognised as intruders and induce an oxidative burst [4]. An increased production of reactive oxygen species (ROS), including superoxides, H2O2 and organic hydroperoxides is an important component of plant defences [5].
