Research Area

Plants are master chemists and produce a large repertoire of secondary metabolites.These small molecules perform plethora of functions, for example, they act as hormones, defense compounds, pharmaceuticals, insecticides, dyes, flavors, and fragrances. Inspite of their tremendous importanc for humans as for the plant itself, plant secondary metabolism remains poorly characterized. Our focus is elucidation of biosynthetic and regulatory pathways of plant secondary metabolism. We use combinatorial OMICS approach for comprehensive investigations and large-scale gene discovery programs in plant secondary metabolism. With integration of transcriptome and metabolome profiling data, we develop extensive collections of genes which are involved in different plant secondary metabolic pathways. This data is also used for discovery of novel regulators of these pathways. Together, this knowledge can be used for engineering of these pathways towards increased yields.We are also working on elucidating biological function of plant secondary metabolites.

Currently our lab is working on Crocus sativus.C. sativus is a triploid, sterile geophyte which has been cultivated and used as spice and medicinal plant since thousands of years. The desiccated stigma of C. sativus forms saffron and is source of various carotenoids and unique compounds called apocarotenoids which are produced by oxidative tailoring of carotenoids. In fact Crocus is the only plant which produces apocarotenoids like crocin, picrocrocin and safranalin significant amounts.These compounds provide color, flavour and aroma to this crop making it world’s costliest spice. In addition, these compounds have a broad spectrum of pharmacological properties as well. In order to understand apocarotenoid biosynthetic pathway and its regulation, we are developing transcriptome map for Crocus. This transcriptome data would be used for identification of genes involved in apocarotenoid biosynthesis and also transcription factors which regulate this process.
