	       ABSTRACT
	       Across the plant kingdom, the jasmonate hormone steers
	       the delicate balance between growth and the activation
	       of defence programs, such as the production of bioactive
	       secondary metabolites. The signaling machinery that
	       established the function of jasmonates as regulators of
	       (secondary) metabolism is conserved and installed early
	       in the higher plant lineage. But, in spite of the
	       similarities of many of the regulators, ultimately
	       species-specific secondary metabolic pathways have
	       evolved under jasmonate control.
	       By using cutting-edge functional genomics tools, in
	       combination with reverse genetics screenings, we try to
	       identify the essential components acting in the
	       jasmonate signalling network, in medicinal plants and in
	       the model plant Arabidopsis thaliana. Such components
	       can ultimately lead to the creation of new metabolic
	       engineering tools that may improve the exploitation of
	       the plant metabolic machinery. Surprisingly, the screens
	       that we have performed not only allowed identifying
	       positive regulators of jasmonate elicitation of
	       metabolism but also revealed the existence of multiple
	       'safety breaks' that serve to optimize plant survival
	       under stress conditions.
