Resumen:
Plants establish multiplekinds of interactions with microorganisms, which can be   neutral, beneficial or detrimental for theplant host. Some interactions involve endophytic microorganisms that colonizeinner parts of plants, in many cases without causing deleterious effects onthem. These endophytes can be able to promoteplant growth both directly or indirectly. Direct plant-growth promotion includeproduction of phytohormones, nitrogen fixation and increase of nutrientavailability. On the other hand, endophytes can promote plant growth indirectlyby contributing to plant health. In this trend, endophytes diminish diseasedevelopment by several mechanisms. Some of them involved direct antagonisticand parasitic interaction between pathogens and endophytes, whereas othermechanism does not require direct interactions because it is based on theability of endophytes to induce systemic resistance in the host, which allow theplant to respond faster and/or more intensively upon pathogen infection.Usually, endophytes share more than one of these mechanisms so the outcome ofthe interaction is the sum of different strategies. Consequently, there isincreasing interest in endophytes as a source of biotechnological products forbiological control. In this chapter, we will review and discuss some examplesof bacterial and fungal endophytes as potential biological control agents andtheir mechanisms of action. We will also analyse thelatest work relating the nutrient uptake/management, specifically iron andnitrogen nutrition, with the biological control exerted by beneficialmicroorganisms.
