Structure – function analysis of cutin and the cuticle in Arabidopsis

Biochemistry

One of the important steps in the evolution of land plants is the formation of a primary barrier at the surface of aerial organs that limit the loss of water: the cuticle. The plant cuticle has evolved to a complex structure consisting of different lipid-derived compounds that plays a role in different aspects of plant biology ranging from stress protection to organ development. The research in our group is particularly directed on the elucidation of new components important for the formation of the cuticle and their significance for different cuticular functions. Arabidopsis thaliana is used as a model system for these studies.
