Signal transduction in plant growth, development, and stress responses: Lipid-mediated signaling; Functional genomics of phospholipases; Metabolic profiling and lipidomics; Metabolic engineering
Research in my laboratory concerns signal transduction processes that regulate plant growth, development, and stress responses. My current research is grouped into four interrelated clusters:
I. Lipid-mediated signaling
II. Functional genomics of phospholipases
III. Metabolic profiling and lipidomics
IV. Metabolic engineering
One major focus in my laboratory is to understand the role of membrane lipids and phospholipases in signaling cascades. Specifically, we are interested in: i) identifying and characterizing enzymes that generate lipid messengers, ii) defining downstream targets of lipid signaling pathways, iii) elucidating the relationship and networks of different signaling processes in hormonal and stress responses, and iv) determining the physiological functions of lipid-mediated signaling. In addition, we are applying knowledge gained from the above studies to manipulating crop plants for improving stress tolerance and productivity. Integrated approaches of molecular biology, biochemistry, cell biology, stress physiology, functional genomics, and metabolomics are employed in our research.
