(A) PR1 is regarded to be secreted via ER, Golgi, TGN and secretory vesicle as shown by an arrow. For the secretion of PR1, AtBET12 and AtMEMB12 control the ER-Golgi trafficking, AtSYP4s (AtSYP41/42/43) does the budding of AtVAMP721/722 vesicles at the TGN, AtSYP121/132-AtSNAP33 at the PM regulate the fusion of AtVAMP721/722 vesicles with the PM. (B) K+ channels and aquaporins are thought to be delivered from the TGN to the PM via AtVAMP721/722 secretory vesicles. Their transport is controlled by AtSYP4s/AtSYP61 at the TGN and by AtSYP121/AtSNAP33 at the PM.
