DR. DEAN'S RESEARCH
Our research primarily involves the study of the metabolism of plant secondary products. Specifically, we are interested in the enzymes that conjugate secondary products to glutathione and glucose and the tonoplast membrane transporters that move these conjugates into the vacuole for safe storage. We are also interested in how the activity and expression of the conjugating enzymes and tonoplast membrane transporters changes during a plants defense response to an invading organism.PUBLICATIONS
