Figure 4

Promoter deletion assay for conserved elements. Top line indicates the non-transcribed sequence of pBBmin with highly conserved blocks shown as blocks (dashed boxes contain predicted binding motifs from FootPrinter, dotted box does not contain a predicted binding motif). Deletion constructs are illustrated in lines on the left side. Bars on the right side indicate mean of petal measurements. Significant changes relative to L.er are marked with * (p < 0.05). All measurements are significantly different to bb-1 (p < 0.03)
