Comparative analysis of conserved sequences within pdm locus enhancers reveals elements shared among SOG enhancers. a Shown is a heat map representation of conserved sequence elements extracted from pdm SOG enhancers and compared to all pdm locus conserved sequence clusters (see Additional file 4: Table S1) using hierarchical clustering among shared conserved elements. Data was normalized to generate standardized scores (Z-scores) illustrated by the color key. The white outlined area represents panel (b), an enlarged portion showing that the 23 pdm SOG enhancers cluster based on these conserved elements. Columns represent shared conserved elements, whereas pdm locus conserved sequence clusters are shown in rows. It is also worth mentioning that the group also contains false positives, or non-SOG conserved sequence clusters (asterisks). Note: a more detailed description of the heat map is available upon request
