Research focus

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 specialized metabolites. By using cutting-edge functional genomics tools, in combination with reverse genetics screenings, we aim to identify the essential components acting in the jasmonate signalling network and to characterize the molecular mechanisms driving plant natural product biosynthesis, in medicinal and model plants.

Plant cells are capable of producing an overwhelming variety of (specialized) metabolites, both in terms of complexity and quantity. These small organic molecules allow plants to cope with various types of stresses but often also have biological activities of high interest to human. Yet, this impressive metabolic machinery is still scarcely exploited, mainly because of the incomplete molecular insight into plant specialized metabolism.
A functional genomics based technology platform has been created that enables comprehensive investigations and large-scale gene discovery programs in jasmonate signalling and plant metabolism. The platform is built on the integration of transcriptome, interactome and metabolome profiling, which drives the design of subsequent reverse genetics screenings in plants or microorganisms. In particular, we exploit the fact that jasmonates can be employed universally across the plant kingdom to modulate both the biosynthesis of the metabolites itself, as well as the formation of the specialized producer cells or storage organs. By profiling jasmonate elicited tissues of amongst others the model plants Arabidopsis thaliana and Medicago truncatula, the crop tomato (Solanum lycopersicum) and medicinal plants such as Catharanthus roseus, Artemisia annua, or Taxus baccata, we have built an extensive collection of thousands of genes potentially involved in all aspects of plant metabolism. Presently we are building platforms for medium-throughput functional analysis of genes encoding transcription factors, E3 ubiquitin ligases and triterpene enzymes.

Our gene collections and functional data will increase our fundamental understanding of the central mechanisms that steer jasmonate signalling in the context of plant growth and metabolism. Simultaneously, they will serve as a novel resource for (metabolic) engineering tools that will facilitate 1) the creation of a synthetic biology program for the sustainable production of existing or novel plant-derived molecules with superior bioactivities for the pharmaceutical, nutraceutical or agrochemical industries and 2) increased crop productivity by improvement of plant growth and defence.
