Benedito, Vagner

Associate Professor of Biochemical Genetics

Vagner Benedito obtained his Ph.D. in Plant Sciences from Wageningen University (The Netherlands) in 2004. He also has a Masters in Horticulture from the University of Sao Paulo (Brazil) and an Agronomy degree from the Federal University of Viçosa (Brazil). Prof. Benedito researches how genes contribute to develop traits of agronomical importance by using biological models. He runs the Laboratory of Plant Functional Genetics, and works to discover and characterize genes involved in symbiotic nitrogen fixation in the model legume, Medicago truncatula, a close relative to alfalfa. He also uses the dwarf tomato cultivar ‘Micro-Tom’ to understand acquisition of competence during in vitro organogenesis of plants, and the metabolism of anthocyanin in different tissues of the tomato fruit. By identifying and characterizing the molecular functions of the genes involved in these processes, his group aims ultimately to contribute with tools to facilitate the development of crops with improved traits, including efficient nitrogen metabolism, fruit and vegetables with improved nutritional value (biofortification) and better protocols to regenerate and propagate plants in vitro.
