Schematic representation of sequence alignments for the 52 HDS S regions. (A) Sequence alignments. The Spec2a S region is shown twice as Spec2a and 1a. The red line within the Spec2a sequence indicates the 78-bp core enhancer. The purple-shaded area shows the comparable sequence alignments of Spec2a with the corresponding regions for the other HDS S regions. Gaps in sequence relative to Spec2a are shown as broken lines. (B) Schematic comparison of forward and reverse orientation for HDS S regions. The diagram depicts the orientation of two sequence blocks for 30 HDS S regions (red and blue) that are reversed in 22 HDS S regions.
