Genetics and Molecular Basis of Physiological Disorders
Instituto de Agroquímica y Tecnología de Alimentos, Spain
Graduate in Biological Science and PhD degree (Plant Physiology) at the University of Valencia. Postdoctoral stay at the University of California (Davis) working in ethylene biosynthesis and action. Since 1993 is working at the Institute of Agro-chemistry and Food Technology of the Spanish National Research Council (CSIC), and he is currently research professor at the Food Biotechnology Department. His current research activities are focused on two main objectives: 1) understanding metabolic pathways related to key components of fruit quality (as regulation of the biosynthesis and accumulation of carotenoids or ascorbic acid, as relevant examples) and 2) physiological and molecular responses of citrus fruits to postharvest stress conditions (chilling injury or water stress-related disorders). In our research projects we incorporated genomics strategies and the genetic diversity to understand the biological and genetic basis of fruit quality and postharvest disorders. We have strong collaborations with other colleagues and research groups around the world, especially but not exclusively, from Citrus-producing countries, and are actively involved in national and international consortiums. L. Zacarias has published more than 100 articles in international peer reviewed journals, review articles and book chapters, and invited to different national and international conferences. He was appointed as Director of the IATA (2004-2011), served in different national research committees and is currently part-time professor of Postharvest Biology in the University of Valencia.
Health Quality of Horticultural Products: Is There a Place for Post-harvest Technologies?
Université Laval, Quebec, Canada
Trained in plant physiology, the laboratory of Dr. Yves Desjardins is using functional genomics tools, metabolomics and proteomics to study the adaptative phenomenon taking place in in vitro plantlets during the transition from heterotrophy to autotrophy and acclimatization. After being the Director of CRH at Laval University, he became involved in health effects of fruits and vegetables and was instrumental in the creation of the Institute of Nutrition and Functional Food (INAF). He has also been elected Chair of the ISHS commission Fruits and Vegetables and Health. He is now interested in the genetics of polyphenols production and accumulation in small fruits, their effect on diabetes, neurodegeneration and gut microbiota. His recent research focuses on the characterization and extraction of polyphenols and particularly proanthocyanidins found in blueberries and cranberries and their effects on cardiovascular diseases, metabolic syndrome, diabetes and other chronic diseases. He is the lead scientist of an important project to determine how polyphenols can modulate positively the gut microbiota and cause a reduction of low-grade inflammation at the origin of many chronic diseases. He collaborates on numerous projects related to health effects of FAV and his involved in a number of clinical trials on the effect of small fruit bioactive compounds (polyphenols) on type-2 diabetes and neurodegenerative diseases. He is the ISHS Board Member responsible for publications (2010-2016).
