Oxidosqualene cyclase involved in the biosynthesis of the cuticular lupeol of glaucous individuals, but not of the glossy phenotype. (S)-2,3-epoxysqualene = lupeol Expressed in stems and laves of glaucous individuals. Not expressed neither in stems or leaves of the glossy phenotype, nor in roots of both phenotypes. Expressed between 6 and 50 days after emergence, with a peak at day 12. Lupeol forms probably the thread-shaped epicuticular wax crystals that hamper insect adhesion and can prevent herbivores from climbing vertical plant structures, a phenomenon known as the 'greasy pole syndrome'. Belongs to the terpene cyclase/mutase family. Get a grip - Issue 135 of January 2012
