Metabolic engineering and synthetic biology of plant metabolites (polyacetylenes, terpenes) Physiological roles of plant secondary metabolites could be reflected through their importance in plant defense against pathogens/predators and different environmental stresses, and as communication molecules when interact between different species. Many plants secondary metabolites are recognized to be major sources for (new) drug discovery, nutrition supplements and are often used as medicine against chronic diseases. Comparative transcriptomics and metabolomics technologies will be used to engineer and elucidate the biosynthesis pathway of plant secondary metabolites (polyacetylenes, terpenes) (Figure 1).

Study plant metabolites induced cellular responses and signal transduction in plants
Plant secondary metabolites are synthesized upon the pathogen attack or mechanical damage, which cause the disruption of plant tissue. However, plant secondary metabolites are toxic for the plant at higher doses. To investigate the molecular mechanisms underlying the recognition/perception and signaling of plant secondary metabolites in plants, available Arabidopsis mutants will be treated with specific metabolites for further transcriptomics and metabolomics profiling studies (Figure 2).
