The cuticle is a hydrophobic barrier that covers the epidermis of all land plants. This barrier is essential to plant survival and protects the plant against various biotic and abiotic stresses. The cuticle layer is also involved in regulating plant development, but the “hows” of this process remain unknown. Plants affected in cuticle composition show defects in the maintenance of several fundamental development steps that are studied in Stéphanie Robert group. In this project the student will use several techniques such as molecular biology, cell biology and biophysics to characterize the essential role of cuticle in plant development.
