characteristics tested as α-ketobutyrate (ACC deaminase), indole acetic acid (IAA) production and phosphate solubilization under such non-stress and stress conditions. Secondary, a microcosm experiment under drought conditions analyzed the effectiveness of five autochthonous AM fungal species single or in consortium inoculated and the impact of autochthonous bacteria in improving plant growth, physiology, nutrition and antioxidant activities as indexes of drought tolerance.
