Dr. María I. Escribano holds a Bachelor's and a PhD in Biological Sciences from the UCM, began her research stage as a collaborator and FPU scholarship holder in the Department of Plant Biology I, studying the hormonal regulation of the reversibility of aging in leaves attached to plants and the mechanisms that regulate the biosynthesis and transport of polyamines, as well as their biological functions. The postdoctoral stage began in 1991 with her incorporation into the research group POSTBIOTEC of the IF-CSIC (actually ICTAN-CSIC). The study of the relevance of free and conjugated polyamines, as well as the regulation of key enzymes involved in their biosynthesis in ripening and in the susceptibility of tropical fruit to low storage temperature, was pioneering in this area. In 1993, she joined Prof. Philip John’s group at the Department of Agricultural Botany, University of Reading (United Kingdom), focusing on his research on the regulation of the ACC oxidase enzyme from custard apple. As a Senior Scientist, since 1997, and through the financing of National Projects, her scientific career focuses on the identification of physiological and biochemical markers functionally involved in the improvement of tolerance to low temperature and in fungal control, activated by treatment with high concentrations of CO2 in climacteric and non-climacteric fruit.
