Fig. 8. (A) surface transport of WAK1-GFP is speeded up by mur1-1. Protoplasts from wild-type (+) and mur1-1 plants were transformed with WAK-GFP and after 1 day were visualized by confocal microscopy. mur1-1 cells were also treated with 2.5 µm isoxaben 1 hour post transformation. Red, chlorophyll; green, GFP. (B) Quantification of WAK1-GFP location in cells on indicated day post transformation. 1, cytoplasmic localization; 5, surface localization. Magnification, x300.
