Research Interests:

The goal of Dr. Guy's research program is to better understand the responses of plants to suboptimal environmental conditions. The rationale for this is that with a better understanding of how plants respond to potentially deleterious situations, better strategies to mitigate crop losses can be devised. The approaches that are used in the three major projects in the laboratory fall into the realms of biochemistry, physiology, and molecular biology. Current Research Interests: The major emphasis of the program is focused on developing a better understanding of the bases of freezing stress tolerance in plants. Our approach ranges from whole plant physiology to molecular biology of the gene. Our ultimate goal is to develop a level of understanding of how hardy plants are able to cope with freezing that will set the stage for efforts to engineer cold tolerance in sensitive species of economic importance.
