Recent inf ormation indicated that sphingolipids are an important class of messenger molecules involved in many significant signal transduction pathw ays regulating cell grow th diff erentiation senescence and apoptosis in mammals and yeast. How ever the biological function of sphingolipids in plants has been explored only recently and remains elusive. Increasing investigation has show n that sphingolipids and their metabolites play an important role in plants. In this review w e describe the structure metabolic pathw ay and biological f unction of sphingolipids.
