The Default Pathway to the Apoplast Does Not Involve the RAB-F2b-Positive PVC.
Confocal analysis of tobacco epidermal cells coexpressing secGFP (A) and secRFP (B). (C) was obtained by merging (A) and (B). Both secGFP (A) and secRFP (B) can be visualized in the ER, but the PVC labeled by secGFP (arrows in [A], [C], and insets) is exclusive of secRFP (arrows in [C] and insets). secRFP was clearly observed in the apoplast where it was stable (B). Bar in (C) = 10 μm for (A) to (C); bar in inset (C) = 3 μm for all insets.
