Engineering the Production of Pharmaceuticals from Plants & Plant Tissue Cultures

In response to attack by pathogens, insects, or herbivores, plants strategically redirect their metabolic resources from growth and development towards the production of defense-related specialized metabolites. This induction of specialized metabolism is also carefully controlled to limit the costly expenditure of resources. The overall vision of our research is to elucidate how plants regulate the production of defense-related specialized metabolites towards engineering their increased biosynthesis in plants and plant tissue cultures.  

Our model system for studying the regulation of defense-related specialized metabolism is the Madagascar periwinkle or the Catharanthus roseus. We chose C. roseus since it produces medicinally-valuable terpenoid indole alkaloids (TIAs), including the anti-cancer compounds vinblastine and vincristine.  These TIAs are produced upon herbivory and the plant deploys sophisticated mechanisms for the transcriptional regulation of its biosynthesis. TIA biosynthesis consists of ~30 enzymatic steps distributed across multiple cell types. The regulation of TIA biosynthesis is similarly complex as multiple transcription factors are required to coordinate the expression of multiple branches of the TIA pathway. In this talk, I will present the role of repressors in the regulatory network and how we devise strategies to reprogram the cell and thus to enhance the production of TIAs.
