Analysis of the expression of the GUS reporter gene driven by various regions of the Petunia hybrida chalcone synthase (chsA) promoter revealed that the developmental and organ-specific expression of the chsA gene is conferred by a TATA proximal module located between -67 and -53, previously designated as the TACPyAT repeats. Histochemical analysis of GUS reporter gene expression revealed that the organ-specific 67 bp promoter fragment directs the same cell-type specificity as a 530 bp promoter… CONTINUE READING
