Divergent Transcriptional Regulatory Logic at the Intersection of Tissue Growth and Developmental Patterning
Figure 7
Sd and Yki regulate the bantam wing enhancer.
(A) ban-wing-lacZ expression in lost in a sdΔB clone (marked by absence of GFP and outlined in white; genotype: sdΔB Minute+), LacZ staining is in red. Expanded grayscale images of the sdΔB clone (GFP, ban-wing) are in panels on right. (B) ban-wing-lacZ with seven Sd motifs mutated (banSd-wing). banSd-wing-lacZ staining is in green, and Hth is in red, with grayscale images in panels on the right. Although most lacZ expression is gone, weak expression remain on either side of the AP compartment boundary. (C) ban-wing-lacZ expression is lost in ykiB5 clones (marked by the absence of GFP; genotype: ykiB5 Minute+; H99/+); LacZ staining is in red, and grayscale images are on right.
