Figure 2.

Promoter comparisons between Drosophila species. Sequence identities (from 50-100%) between different Drosophila species ranging from D. melanogaster to the most distant D. virilis as calculated and presented in the VISTA interface [91] for two dRfx target genes, CG9595 (osm-6/NDG5) and CG8853 (IFT55/che-13/Hippi). Coding sequences are depicted in dark blue, untranslated regions are in light blue and other conserved regions in pink. Gene orientation is shown by a horizontal arrow. The location of conserved X-boxes for each gene is indicated by numbered vertical arrows. Note that one conserved X-box for osm-6 is in a conserved block of sequence, while others (osm-6 and che-13) are not.
