Plants are synthesis chemists par excellence. My research aims to understand how plants organize their synthesis and transport of natural substances. I have a particular focus on glucosinolates, also known as mustard, which are found in plants of the Crucififlower family, which include oilseed rape, vegetables such as cabbage and broccoli, as well as the weed Plant Goose Semad (Arabidopsis thaliana). The latter has the status of model plant. The plants use glucosinolates as defences against insects and microorganisms. Glucosinolates are relevant to humans because of their cancer-prevention properties, their potential as biopesticides, and as flavouring substances, for example. The sharp taste in wasabi. I will tell you about my work on the one hand to produce the healthy glucosinolates in microorganisms and partly to remove unwanted glucosinolates from the rape cake.
