Environmental Stress & Molecular Biology

Our research focus and efforts have been to understand plant adaptations, tolerance and mechanisms of injury in relation to various environmental stresses including low temperatures, high temperatures, water deficit and hypoxia, and to develop methods and strategies to improve plant tolerance in many horticultural crops especially in food crops and turfgrasses. Wide ranging approaches are being used to accomplish these goals, including those that aim at the molecular, cellular and whole plant level.

Other areas of research involve beneficial aspects of environmental stresses. In response to various stresses, plants accumulate health-promoting antioxidants and secondary metabolites (phytochemicals) as a defense mechanism. Studies are being conducted to develop strategies to use environmental stresses and biotechnology tools to augment health-promoting phytochemicals in fruits and vegetables.
