Figure 7. Amphimedon enhancer-like elements are enriched in metazoan-specific microsyntenic units.
(A) Putative adult and larva enhancer-like signatures identified in the 60 metazoan-specific microsyntenic pairs investigated. (B) The cladogram represents known phylogenetic distribution of the Isl2-Scaper microsyntenic gene pair across opisthokonts. The orientation of the arrow corresponds to gene orientation. Isl2-Scaper is not conserved in yeast, Capsaspora, Nematostella and C. elegans. (C) Enhancer elements in the Isl-Scaper microsyntenic gene pair locus in Amphimedon. Scaper and Isl genes (purple) are shown, along with input DNA-normalized coverage of H3K4me3 and H3K4me1 and RNA-seq expression in both adult and larva. Regions of enrichments (high confidence peaks, representing reproducible events across true biological replicates) corresponding to the predicted enhancer-like elements located within the introns of Scaper are highlighted in grey.
