“…The formation of new cisternae on one face of a Golgi apparatus stack would be required to compensate for loss of cisternae from the opposite face of the stack. The source of these new cisternae was suggested early on t o be a special region of the endoplasmic reticulum which gives rise to transition vesicles that move to, and condense on, the forming (cis) faces of the Golgi apparatus stacks where they would fuse together to form the new cisternae (Zeigel and Dalton, 1962;Morre and Mollenhauer, 1976). Alternatively, movement of materials may occur via shuttle vesicles a t the peripheries of the cisternae to effect transfer from one cisterna to the next (Orci et al, 1986).…”

In 1898, Camillio Golgi reported a new cellular constituent with the form of an extensive intracellular network (the apparato reticolare interno), which now bears his name. However, the history of Golgi's apparatus is replete with controversy regarding its reality, what components of the cell should be included under its aegis, and what terminology should be used when referring to it. Electron microscopy has resolved many of these controversies and it is appropriate that this volume emphasize that aspect of Golgi apparatus discovery. The principal structural component of the Golgi apparatus is the stack of cisternae, or dictyosome. As determined both biochemically and at the level of electron microscopy, the dictyosome is a highly ordered and polarized structure. The maintenance of order within the stack is thought to result from either intercisternal bonding constituents, or filamentous structures (or both) that bridge the space between adjacent cisternae. Mechanisms proposed for movement of membrane and product into and out of the dictyosome (i.e., the Golgi apparatus stack) include a serial mode which functions exclusively by the formation, displacement, and loss of cisternae from the stack, and a parallel mode which functions exclusively by the movement of membrane, product, or precursor molecules directly into the peripheral edges of the cisternae. In the parallel mode, all cisternae can be accessed either singly or simultaneously, at least in theory, at any position within the stack. It is probable that both the serial and the parallel modes function concomitantly and need not be mutually exclusive. Finally, the peripheral tubules of the cisternae represent a major membranous constituent of the cell with potentially unique functions. These tubules interconnect cisternae of adjacent stacks and may represent the major site of receptors for the shuttle (i.e., parallel) type of transfer among cisternae. Peripheral tubules as extensions of the cisternal lumina into the cytoplasm presumably have other functions, but these, like the tubules themselves, have only rarely been accommodated into functional models of Golgi apparatus dynamics in secretion or membrane flow.

Ultrastructural studies of the ovary wall and pericarp of Asclepias curassavica L. II. Mesocarp development With 3 Figures

The present article describes various subcellular changes occurring during development and maturation of the mesocarp of Asclepias curassavica follicle. The ground tissue of the ovary wall consists of dense cytoplasm containing cell organelles like mitochondria, endoplasmic reticulum, chloroplast, ribosomes etc. Mesocarp developing from the ground tissue is differentiated into three zones on the basis of cell shape and degree of vacuolation. Chloroplasts possess starch grains which have a central electron translucent area and a peripheral electron opaque boundary. In the mature fruit the mesocarpic cells are highly vacuolated with a peripheral layer of cytoplasm. The cytoplasm seems to be loose or less denser than that of the developing mesocarpic cells, but contains all the cell organelles that are present in the developing mesocarp.
