Localization of GFP in transgenic tobacco as directed by the signal peptide of Vv-AMP1. Localization of GFP observed in the apoplasts of the following tissues, organs and cells in the leaf petiole: (A) cortex; (B) the guard cells of the stomata and (C) the trichoma. A1, B1 and C1 show light microscopic photos of these various tissues and organs from the untransformed control. A2, B2 and C2 show the auto-fluorescence from these same fields in the untransformed controls, whereas A3, B3 and C3 indicate GFP expression in the apoplastic regions of these structures in the GFP overexpressing lines.
