Cytomembrane Differentiation in the Endoplasmic Reticulum-Golgi Apparatus-Vesicle Complex

Abstract

Diversity of cytomembrane types is confirmed in hyphae of the fungus Pythium ultimum by electron microscopy. A transition in membrane morphology across stacks of dictyosome cisternae (from endoplasmic reticulumlike at one pole to plasma membrane-like at the opposite pole) suggests that dictyosomes of the Golgi apparatus are sites of membrane interconversion.
