Conserved and Plant-Unique Mechanisms Regulating Plant Post-Golgi Traffic
Membrane traffic plays crucial roles in diverse aspects of cellular and organelle functions in eukaryotic cells. Molecular machineries regulating each step of membrane traffic including the formation, tethering, and fusion of membrane carriers are largely conserved among various organisms, which suggests that the framework of membrane traffic is commonly shared among eukaryotic lineages. Howeve...
متن کاملBiogenesis of the plant Golgi apparatus.
It has long been assumed that the individual cisternal stacks that comprise the plant Golgi apparatus multiply by some kind of fission process. However, more recently, it has been demonstrated that the Golgi apparatus can be experimentally disassembled and the reformation process from the ER (endoplasmic reticulum) monitored sequentially using confocal fluorescence and electron microscopy. Some...
متن کاملTraffic between the plant endoplasmic reticulum and Golgi apparatus: to the Golgi and beyond.
Significant advances have been made in recent years that have increased our understanding of the trafficking to and from membranes that are functionally linked to the Golgi apparatus in plants. New routes from the Golgi to organelles outside the secretory pathway are now being identified, revealing the importance of the Golgi apparatus as a major sorting station in the plant cell. This review d...
متن کاملStructure of Isolated Plant Golgi Apparatus Revealed by Negative Staining
Sucrose-gradient-purified dictyosomes of plant Golgi apparatus appear, after glutaraldehyde stabilization, as stacks of highly fenestrate and tubate cisternae when negatively stained with phosphotungstic acid, shadowed with heavy metal, or OsO(4)-stained in thin section. The tubular proliferations (diameter 200 to 400 A) extend for several microns from the central region and are united at inter...
متن کاملStructural differences contrast higher plant and animal Golgi apparatus.
The intercisternal spacings between cisternae of dictyosomes of higher plants differ from those of mammalian dictyosomes. In plants, the spacings increase from an average of about 8.0 nm at the forming face to about 14.0 nm at the maturing face. The increase in spacing coincides with the appearance within the intercisternal space of parallel filaments called intercisternal elements. In mammals,...
