Figure 1. Activation tag vector. The vector contains multimerized auliflower Mosaic Virus (CaMV) 35S enhancer that can function in either orientation and can cause transcriptional activation of nearby genes resulting in dominant gain of function mutations. RB and LB represent right and left borders of T-DNA, respectively. The activation of plant gene by enhancer elements is indicated by broken arrow (black). The flanking plant DNA is shown in green.
