Monoterpene secoiridoid biosynthesis contributes the terpene component of terpenoid indole alkaloids produced in the medicinal plant Catharanthus roseus. The thesis focuses on the development of fundamental knowledge and methodology to reconstruct the monoterpene secoiridoid pathway in tobacco plants using metabolic engineering. The thrust of the thesis concentrated on remaining challenges to engineer complex secondary metabolic pathways in plants. We focused on the early part of the pathway and we recovered a population of transgenic tobacco plants expressing different combinations of transgenes. Analysis at metabolomic and transcriptomic levels provided novel insights into remaining bottlenecks for the effective engineering of secondary metabolic pathways in plants. The experimental part of the thesis is complemented by the development of a systematic patent search to create an IP database with all relevant patents related with the engineering of terpenoid indole alkaloid pathway in plants.
