Figure 2.

Schematic representations of the effector and reporter constructs used for transient expression analyses. Effector constructs contain the cauliflower mosaic virus 35S promoter fused to the respective effector ORFs followed by the nopaline synthase terminator (nosT). Reporter constructs contain the respective target promoters fused to the uidA-ORF followed by nosT. The length of the individual promoter fragments used is indicated. The three mutated variants of the CHS minimal promoter are named according to the mutated cis-element, respectively.
