Research Areas

  • Biochemistry of floral scent volatiles
  • Natural products from root cultures
  • Secondary metabolism - molecular biology
  • Histochemistry of plant metabolites
  • Metabolic physiology of aromatic plants
The major focus of my group is on plant natural product biotechnology with emphasis on plant volatiles and specialized metabolism. Our broad aim is the investigation of the properties of plants as they relate to food and other post-harvest uses, including for example, flavour/fragrance and bioactive compounds. In addition to phytochemical analysis, we continue to do plant cell and organ cultures for studying of enzyme activities  and gene expressions responsible for the synthesis of natural products of our interest.
The current research areas of this group are -
Mechanistic understanding of floral and foliar extrafloral nectar secretion in relation to the biosynthesis of floral scent volatiles
Understanding epicuticular wax deposition and scent emission in tuberose flowers
Evaluating spectral light quality on the synthesis of ascorbic acid and terpenoid volatiles in Coriandrum sativum and Plectrathus amboinicus
Generating anthocyanin and other value-added metabolome in Melissa officinalis leaves upon post-harvest treatment
Targeted metabolomics of floral secretory products and extrafloral nectaries
Understanding essential oils secretory system in vegetative organs of Lauraceae and Myrtaceae members

Our specialized facilities include two HPLCs, two UV-VIS spectrophotometers, GC-MS, GC-FID, refrigerated centrifuge, , thermocyclers, electrophoresis systems, minus 20  and minus 80 freezers, gel documentation system, lyophilizer, vacuum concentrators, rotary vacuum evaporator, fluorescence and stereo-zoom microscopes, rotary microtome, plant growth chamber,  plant cell & tissue culture facility, experimental garden and a dedicated temperature and humidity controlled greenhouse with photoperiodic illumination facility.
 
Current research projects are supported SERB, DST (SEED), DST (International Div), and DBT.  A number of projects involve collaboration with other partners such as, Mizoram University under DBT NER-BPMC progarmme, CSIR-IHBT Palampur and YSPUHF Solan under DST ASACODER programme, Komarov Botanical Institute at Saint Petersburg (Russian Academy of Science) under DST-RFBR funding, Uniersity of Wroclaw (Poland) under INSA-PAS exchange programme  and  Technical University of Braunschweig (Germany) under DAAD IIT-TU9 KOPSIE programme.
