Course Synopsis

This course provides preliminary learning regarding the in vitro production of valuable plant constituents using plant cell and organ culture. The techniques used to regenerate plants under in vitro conditions and to enhance the production of secondary metabolites using plant cell and organ cultures. The strategies used to obtain pharmacologically active metabolites at industrial level are also focused.

Course Learning Outcomes

• To understand and exploit the extraordinary diversity of the plant biochemical capacity to produce valuable molecules. • To functionally analyse the genes of interest and systematically explore factors that control the formation, regulation, transport, stability and storage of secondary metabolites. • To combine knowledge of the molecular regulation in vitro and in planta in order to develop a holistic and integrated view of secondary metabolite pathways and their products at systems level. • To develop and optimize methods for large-scale cultivation and downstream processing of secondary metabolites addressing bio-safety issues in transgenic plants and cell cultures.
