My PhD project is centered in the identification of the early enzymatic steps targeted by FAC signaling in the oxylipin biosynthesis and metabolic pathways in N. attenuata. The project also entails the study of how other hormone signaling pathways (e.g., SA) and specific regulatory components (e.g., WIPK) influence the early FAC-triggered responses on the oxylipin synthesis pathway. For this purpose, native wild type N. attenuata plants and already available RNAi-lines, showing different JA responses after wounding and FAC elicitation, will be analyzed. In addition to biochemical approaches ecological studies in N. attenuata’s natural habitat are included to explore the role of early activated metabolic pathways with respect to fitness and herbivore community of N. attenuata.
