Deep conservation of cis-regulatory elements and chromatin organization in echinoderms uncover ancestral regulatory features of animal genomes [Hi-C]
we generated new reference genome assemblies for two species belonging to two different echinoderm classes: the bat sea star Patiria miniata and  the purple sea urchin Strongylocentrotus purpuratus Overall design: Hi-C assays in wild-type sea star and sea urchin whole embryos at late gastrula
