Abstract:
Endomembrane trafficking pathways involving exocyst complexes function. The two established pathways — exocytosis of TGN/EE produced vesicles mediated by EXO70A1 harbouring exocyst and EXO70B1 dependent autophagy related transport to the vacuole — are highlighted by solid arrows; other putative pathways are marked by the dashed arrows. A, autophagosome and autophagy related GA-independent traffic; CW, cell wall; ER, endoplasmic reticulum; GA, Golgi; IVB, intravacuolar bodies; MVB, multivesicular bodies; PM, cytoplasmic membrane; TGN/EE, trans-Golgi network/early endosome; TN, tonoplast; V, vacuole. Exocyst complexes with different EXO70 subunits are symbolized by diamonds connecting the transport containers to the target membranes.
