Vesicles versus Tubes: Is Endoplasmic Reticulum-Golgi Transport in Plants Fundamentally Different from Other Eukaryotes?
The endoplasmic reticulum (ER) is the gateway to the secretory pathway in all eukaryotic cells. Its products subsequently pass through the Golgi apparatus on the way to the cell surface (true secretion) or to the lytic compartment of the cell (vacuolar protein transport). In animal cells, the Golgi apparatus is present as a stationary larger order complex near the nucleus, and transport between...
متن کاملER and vacuoles: never been closer
The endoplasmic reticulum (ER) represents the gateway for intracellular trafficking of membrane proteins, soluble cargoes and lipids. In all eukaryotes, the best described mechanism of exiting the ER is via COPII-coated vesicles, which transport both membrane proteins and soluble cargoes to the cis-Golgi. The vacuole, together with the plasma membrane, is the most distal point of the secretory ...
متن کاملProtein recycling from the Golgi apparatus to the endoplasmic reticulum in plants and its minor contribution to calreticulin retention.
Using pulse-chase experiments combined with immunoprecipitation and N-glycan structural analysis, we showed that the retrieval mechanism of proteins from post-endoplasmic reticulum (post-ER) compartments is active in plant cells at levels similar to those described previously for animal cells. For instance, recycling from the Golgi apparatus back to the ER is sufficient to block the secretion o...
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 کاملIn tobacco leaf epidermal cells, the integrity of protein export from the endoplasmic reticulum and of ER export sites depends on active COPI machinery.
Trafficking of secretory proteins between the endoplasmic reticulum (ER) and the Golgi apparatus depends on coat protein complexes I (COPI) and II (COPII) machineries. To date, full characterization of the distribution and dynamics of these machineries in plant cells remains elusive. Furthermore, except for a presumed linkage between COPI and COPII for the maintenance of ER protein export, the ...
