My research is a balance between applied and basic with an emphasis on the translational potential, and focus on the targeted improvement of small grain cereals. In this direction, I am applying and improvising tools and techniques of both structural and functional genomics as and when applicable in my research. My major research interests include but are not limited to the development of i) natural dietary therapies for the ‘gluten syndrome’ by engineering nutritionally enhanced wheat genotypes with reduced amount of immunogenic gluten proteins and glycemically rich amylopectin; ii) genetically resistant wheat and barley genotypes for major root pathogens of the U.S. Pacific Northwest by biomimetic engineering of wheat lines to produce an antifungal antibiotic pyrrolnitrin, and systemic expression of an antimycotic enzyme endochitinase; and iii) herbicide (imidazolinone) tolerant, nutritionally enhanced and commercially valuable barley cultivars by breeding for reduced proanthocyanidin and increased lysine contents. From the basic research, I am interested in deciphering: (a) genes and signaling pathways contributing to yield stability under stress environments; (b) molecular mechanism underlying the diploid-like pairing behaviors of polyploidy wheat; and (c) molecular and cytogenetic events that shaped wheat genome following allopolyploidization.
