CRE turnover events at chaperone promoters within Notothenioidei. phastCons scores estimated for all 32 species examined in this study (Perciform) and the Notothenioidei subset of this phylogeny (Notothen) are plotted across 5′ – 3′ promoter ends. Grey annotations depict the absence of data. Orange annotations depict significantly accelerated rates of mutation within Cryonotothenioidei and yellow annotations depict the same for younger cryonotothen lineages. Blue bars depict CRE gains in either subpolar notothens (dark blue), Cryonototheniodei (blue) or younger cryonotothen lineages (light blue). Red annotations depict CRE losses in either Cryonotothenioidei (dark red) or younger cryonotothen lineages (light red). Green annotations depict significant CRE conservation in Cryonotothenioidei relative to other species
