People-Plant Interactions

People-Plant Interactions form the basis for all facets of environmental horticulture, whether it be “in the eye of the beholder,” the scent of a flower, the soft feel of a carpet of lawn, or in human health and well-being. Dr. Guy conducts research on the basic aspects of people-plant interactions as they relate to therapeutic horticulture. The research program is aimed at a characterization of brain activity and functioning resulting from people-plant encounters using functional magnetic resonance imaging technology. The goal is to connect changes in brain activity and function with the therapeutic benefits provided by plants associated with reductions in stress, anxiety and depression and increases in well-being and quality of life.

Plant Cold Hardiness

Plants by their sessile nature must have highly developed mechanisms to sense temperature conditions and mobilize genetic and physiological responses that will enhance their ability to survive temperature extremes. Exposure to low temperatures elicits complex changes in gene expression and physiology that help to maximize survival. Dr. Guy seeks to understand the changes that take place in plant cells that lead to increases in tolerance to freezing stress.
