Bio/Research

My research is primarily in the area of biochemistry, specifically pertaining to fruits and vegetables, and in relation to their senescence (ethylene, signal transduction, calcium second messenger system), shelf life and quality, nutraceutical ingredients and their mechanism of action. Recent research includes investigations on the role of phospholipase D (PLD) in membrane homeostasis and signal transduction. Structural and enzymological properties of recombinant PLD alpha will be investigated through site-directed mutagenesis of active- and regulatory-motifs, and its effect on various aspects of enzyme function. Technologies have been developed for enhancing the shelf life and quality of fruits, vegetables and flowers, based on the inhibition of PLD. Understanding the mechanism of action of food components in terms of disease prevention has become a major topic of my research. In this context, the biochemical mechanisms of action of grape/ wine polyphenols on cell growth and their importance in cancer prevention are being investigated using mammalian cell lines and athymic mouse model system. In total, my research is focussed on understanding the biochemical and molecular mechanisms of the developmental processes in fruits and vegetables and their role as functional foods in disease-prevention.
