A distinct pathway for polar exocytosis in plant cell wall formation
Post-Golgi protein sorting and trafficking to the plasma membrane (PM) is generally believed
to occur via the trans-Golgi network (TGN). In this study using Nicotiana tabacum pectin
methylesterase (NtPPME1) as a marker, we have identified a TGN-independent polar
exocytosis pathway that mediates cell wall formation during cell expansion and cytokinesis.
Confocal immunofluorescence and immunogold electron microscopy studies demonstrated
that Golgi-derived secretory vesicles (GDSVs) labeled by NtPPME1-GFP are distinct from …
