International audience. Potato cultivation has a strategic role as a food source for the human population. Its promising future development relies on improving the control of the numerous microbial diseases that affect its growth. Numerous and recent studies on the potato rhizosphere, mycorrhizosphere and endorhiza reveal the presence of a diverse and dense microbial community. This microbial community constitutes a rich source for plant growth-promoting rhizobacteria and biocontrol agents. So far, the beneficial effects achieved are related to microbial siderophores, antibiotics, biosynthesis of surfactants and phytohormones, nutrient and spatial competition, mycoparasitism, induced systemic resistance, phage therapy, quorum quenching and construction of transgenic lines. Considering the crucial role for food and the diversity of mechanisms involved in growth promotion and microbial protection, potato constitutes a historical and accurate model in developing new biocontrol strategies.
