Fig. 7. A schematic model of two distinct trafficking zones of the TGN.

Fig. 7

The Golgi-associated TGN (GA-TGN) has at least two zones, the secretory-trafficking zone and the vacuolar-trafficking zone, which we propose are responsible for distinct cargo sorting in Arabidopsis root epidermal cells. The secretory-trafficking zone consists of R-SNARE VAMP721 (pale gray), adaptor protein AP-1 (magenta), coat protein clathrin (black). The vacuolar-trafficking zone consists of R-SNARE VAMP727 (dark gray) and adaptor protein AP-4 (green). From the secretory-trafficking zone, some of the TGN detaches as the Golgi-released independent TGN (GI-TGN) in a form of a vesicle/bud cluster including clathrin-coated vesicles/buds.
