摘要
Immunity and senescence play a crucial role in the functioning of the legume symbiotic nodules.The miss-regulation of one of these processes compromises the symbiosis leading to death of the endosymbiont and the arrest of the nodule functioning.The relationship between immunity and senescence has been exten-sively studied in plant organs where a synergistic response can be observed.However,the interplay be-tween immunity and senescence in the symbiotic organ is poorly discussed in the literature and these phe-nomena are often mixed up.Recent studies revealed that the cooperation between immunity and senescence is not always observed in the nodule,suggesting complex interactions between these two pro-cesses within the symbiotic organ.Here,we discuss recent results on the interplay between immunity and senescence in the nodule and the specificities of this relationship during legume-rhizobium symbiosis.
