a Arrangement of DMBT1 gene tandem repeats (grey), Hox genes and Hox-like genes (red) on the pseudo-chromosome Chr11 and their expression patterns in four types of tissues including mantle, scale-secreting epithelium, gill, oesophageal gland (OG); darker shades indicate higher levels of expression. SRCR (scavenger receptor cysteine-rich) domain, scavenger receptor cysteine-rich domain. Source data are provided as a Source Data file. b Tissue-specific expression patterns of transcriptome factors shown with in situ hybridisation, including Hox4 and Hox1 in the mantle edge (arrowheads; additional tissue is visible in the background including scales also expressing Hox1) and tissue sections of the scale-secreting epithelium expressing Evx and Hox3. Scale bars = 500 μm for mantle and 100 μm for scales. In situ hybridisation experiments were repeated independently on three individuals (twice on each individual for Hox1 and Hox3, once for Hox4 and Evx) with similar results.
