Joy Bergelson, Ph.D.Coevolutionary and Ecological Dynamics Between Arabidopsis thaliana and its Bacterial PathogensResearch SummaryThe research in my laboratory focuses primarily on the ecology and evolution of plant resistance traits. Our approach is to combine ecological field experiments with transgenic manipulations in order to explore the fitness effects and selective histories of particular resistance genes. Recent work attempts to determine the evolutionary dynamics of resistance genes involved in gene-for-gene interactions with plant pathogens, and to determine the pleiotropic fitness effects of resistance (to plant pathogens, herbivores and herbicides), at both physiological and population levels. A variety of experimental systems are currently being used in the laboratory, including rabidopsis thaliana, Brassica napus. Atropa belladonna and Ipomopsis aggregata. In addition, I maintain a broad interest in plant population biology and am involved in projects on weed invasiveness, plant population dynamics, plant quantitative genetics and global environment change in both natural and experimental systems.
