Research Area
Initially, my laboratory studied the interactions of developmental and light regulatory signals in the regulation of the chlorophyll a/b binding protein genes of soybean. In 1990, my laboratory's emphasis shifted dramatically to focus on understanding plant responses to wounding, pathogens, and herbivores. Two research projects dominate our current research initiatives. First, we are dissecting the mechanisms used to perceive phloem-feeding whiteflies in squash, tomato and Arabidopsis. Second, we identified a peptidase (leucine aminopeptidase) that responds to bacterial pathogens, wounding and tissue-damaging herbivores. This enzyme has led us into studies to understand the role of N-terminal processing enzymes during development and in response to stress. We utilize multidisciplinary approaches in both projects by incorporating the tools of biochemistry, genetics, cell biology, and genomics.
