Figure 2.
A group of genes found by our method and examples of detected motifs along with some retrieved genes. The gene group SQ was obtained by finding a tight image-cluster for stage 7–8 (highlighted) and their known biological connection is described in the text. For each gene in SQ, one representative embryo image is shown for each stage-range, followed by the respective eigen-profile (except for snail and tkv at stage 9–10 for which there is no appropriate lateral-view image in our data). Three motifs detected using the entire upstream regions of the homologous genes in eight fly species are shown, along with two or three randomly selected example genes in the subsequent genome-wide motif scanning results. BDGP ISH images (in blue) and abbreviations (see Appendix A) of their anatomical annotations are also shown, without image cropping or orientation correction.
