Fig. 5.

Three CNEs are not detectable in the pipefish dlx1a-dlx2a cluster. One CNE present in other teleosts and mammals is missing from a gapless region between exon1 and -2 in the S. scovelli assembly (red arrow). Two other CNEs in the dlx intergenic region that are conserved among percomorphs are also missing from this region in pipefish (orange arrows). Two CNEs previously shown to direct reporter gene expression in murine Dlx expression domains are boxed [43]. Exons are highlighted in blue, CNEs in pink. The reference, Ola, is medaka; Hsa, human; Dre, zebrafish; Gmo, cod; Ssc, pipefish; Tor, tuna; Gac, stickleback; Tru, pufferfish
