Orbicule wall surface characteristics in Lilium (Liliaceae): An ultrastructural and cytochemical approach
Year: 1993
Type: article
Abstract: In Lilium cv. enchantment, an orbicule peripheral sheet is characterized. It is 10 nm thick and surrounds the whole Ubisch body. Ultrastructural and cytochemical observations allow us to propose that the orbicule peripheral sheet represents remnants of a glycocalyx supported by the membrane limiting orbicule core on which sporopollenin is synthesized. A model of orbicule sporopollenin architecture and biosynthesis is discussed.
