Towards understanding the relation between the composition, structure and the function of the plant cuticle
During recent years, we have used Arabidopsis as a model system for the identification of genes involved in the biosynthesis of cutin, the structural polyester of the cuticle. A number of Arabidopsis mutants having a permeable cuticle have been isolated using dyes that penetrate the leaves or petals only when the cuticle is disrupted. Characterization of permeable cuticle mutants lead also to a better understanding of the different roles of the plant cuticle in stress protection and plant development.
A short overview over the different research projects is given below:
