Figure 4

(a) Histochemical localization of GUS activity in transgenic plants expressing the GUS reporter gene under the control of the GTR1 promoter. GTR1 was expressed in stamen filaments (left panel), base of filaments (middle panel) and anthers (right panel). Scale bar, 1 mm (left panel) and 100 μm (middle and right panels). (b) Vertical section of a proGTR1::GUS flower at stage 12. fi, filament. Scale bar, 100 μm. (c) Transverse section of a proGTR1::GUS flower at stage 13. pi, pistil; st, stomium; v, vascular bundle. Scale bar, 100 μm. (d) Vertical section of a proGTR1::GUS flower at stage 14. Scale bar, 100 μm. (e) Transverse section of a proGTR1::GUS flower at stage 12. Scale bar, 100 μm. (f) Transverse section of a proGTR1::GUS flower at stage 13. Scale bar, 20 μm.
