Fig. 5. Analysis of the AmMYBML1 promoter. (A) The AmMYBML1 promoter, showing the locations of the TATA box, putative I-boxes, CArG boxes and the MYB-binding site II (MBSII), recognised by proteins such as GAMYB (Solano et al., 1995). The different lengths of the promoter fragments tested in GUS reporter assays in tobacco are indicated in different shades of grey; 1571 bp fragment in white, 1260 bp fragment in very pale grey, 884 bp promoter in mid grey, 223 bp promoter in darker grey. (B) Expression of GUS driven by the full-length AmMYBML1 (1571 bp) promoter in tobacco petal trichomes. (C) Expression of GUS driven by the full-length AmMYBML1 promoter in tobacco petal conical cells. (D) Expression of GUS driven by the 884 bp AmMYBML1 promoter in tobacco leaf vascular tissue. (E) Expression of GUS driven by the 884 bp AmMYBML1 promoter in the trichomes of tobacco leaves.
