Sepsid even-skipped Enhancers Are Functionally Conserved in Drosophila Despite Lack of Sequence Conservation
Figure 4
Expression of eve and its upstream transcriptional regulators is conserved between Drosophila melanogaster and the sepsid Themira minor.
Expression patterns were visualized by in situ hybridization with species-specific digoxigenin-labeled antisense RNA probes. The gap transcription factors hb, gt and Kr are expressed in similar domains during stage 5 in D. melanogaster (A–C) and T. minor (E–G). eve is expressed in seven transverse stripes during cellularization in both species (D, H). Embryos are oriented with anterior to the left and dorsal up.
