title: Importance of plant sterols in pattern formation and hormone signalling.
abstract: The recent identification of sterol mutants in plants has shown that these molecules play essential roles in development. Although several such mutants are dwarfed, predominantly because of the reduced accumulation of brassinosteroids, others show distinctive phenotypes. We put forward the view that sterols also have roles in mediating brassinosteroid-independent signalling, in the trafficking of membrane vesicles that transport key regulatory proteins and in correct signalling protein conformation and function in membranes.
