Peptides derived from the auxin binding protein elevate Ca2+ and pH in stomatal guard cells of Vicia faba: a confocal fluorescence ratio imaging study.
- Abstract:
-
Dual-excitation confocal laser scanning microscopy (CLSM) was used to image the pH-indicator, BCECF, iontophoretically microinjected into stomatal guard cells of Vicia faba during challenge with peptides derived from hydrophilic domains of the maize auxin-binding protein. Only the peptide corresponding to the C-terminal end (Pz151-163) caused significant changes in cytosolic pH, stimulating rapid alkalinisation of 0.4 +/- 0.1 pH units. Cytosolic pH was clamped using the permeant weak acid, bu...
