Juan Manuel Ruiz-Lozano currently works as a Research Scientist at CSIC in the Department of Soil Microbiology and Symbiotic Systems from the Estación Experimental del Zaidín, Granada, Spain. He got his degree in biology in 1991, and then he completed a Ph.D. thesis in biology at the University of Granada, Granada, Spain, in 1995. After that, he started two postdoctoral stays first at INRA in Dijon, France, and then at the University of Turin, Turin, Italy. Since 2000 he focused his research activities on elucidating the physiological and molecular mechanisms by which the arbuscular mycorrhizal (AM) symbiosis enhances the tolerance of the host plants to the water deficit imposed by osmotic stresses. In this way he has demonstrated the ability of the AM fungal mycelium to take up water from sources inaccessible to roots and transfer this water to the host plant. The induction by arbuscular mycorrhizal of antioxidant enzyme activities and accumulation of nonenzymatic antioxidant compounds have been also demonstrated in different plants, with subsequent reduction in oxidative damage in AM plants. More recently, the research activities are focused on elucidation of how the AM symbiosis regulates plant aquaporins and the subsequent effects on plant water status and root hydraulic properties, under different osmotic stresses.
