Planter udviser en utrolig plasticitet i deres respons på et foranderligt miljø. Under forskellige miljømæssige stimuli varierer planter deres ressourcefordeling mellem generel og specialiseret metabolisme. Interaktionen mellem generel og specialiseret metabolisme påvirker planternes ydeevne og har også indvirkning på fordøjelighed og toksicitet. I en tidsalder, hvor temperaturer og atmosfæriske forhold ændrer sig i hidtil uset tempo, er vi nødt til bedre at forstådenne interaktion for at forbedre afgrøders ydeevne og bevare dyrelivet.

Vores forskning sigter på at forstå den molekylære regulering og evolution af planters metaboliske veje samt at tilvejebringe grundlæggende viden, der kan anvendes inden for miljømæssige, landbrugsmæssige og bioteknologiske platforme. Dette opnår vi ved at anvende en fuld "omik"-værktøjskasse – fra drivhus til mark.

Videnskabelige highlights

  • Using a multi-disciplinary approach, our research has established an intricate interplay between plant general and specialized metabolism. We have demonstrated that plants exhibit a metabolic shift in chemistry in response to developmental and environmental change; in the glasshouse and in the field. The redirection of resources between general and specialized metabolism can improve plant growth and performance under adverse conditions. This metabolic shift, however, has significant consequences for plant toxicity and nutritional content, and downstream consequences on different trophic levels.

  • We have optimized analytical methods to separate and analyze complex plant mixtures. We are currently identifying key biosynthetic pathway members involved in the biosynthesis of different specialized metabolite classes, combining transcriptomic and proteomic analyses.
