Current Research

Regulation and the role of sterols in plant stress responses

Eukaryotic organisms use sterols to regulate fluidity and permeability of their cell membranes. The interaction of sterols with sphingolipids in lipid rafts is necessary for correct signaling and activity of membrane proteins. Plants produce several sterols which vary in proportions in different organs. The gap in our knowledge is about how sterol metabolism is regulated in plants, and the role of sterols in crop stress physiology. Lack of knowledge of mechanisms regulating sterol metabolism in plants prevents our full understanding of the direct role of sterols in plant response and tolerance to stress. The overall goal of my research is to understand how sterol metabolism is regulated in plants. Ultimately, the findings from my research will be used to enhance stress tolerance and nutritional quality of crop plants by genetic or transgenic approaches.
