Abstract excerpt
The creation, preservation, and degeneration of cis-regulatory elements controlling developmental gene expression are fundamental genome-level evolutionary processes about which little is known. Here, we identify critical differences in cis-regulatory elements controlling the expression of the sea urchin aboral ectoderm-specific spec genes. We found multiple copies of a repetitive sequence element termed RSR in...
