Emergence of novel cephalopod gene regulation and expression through large-scale genome reorganization

Abstract

Cephalopods are an enigmatic animal group with complex and adaptive behaviors such as camouflage; however the genetic basis for these traits is not well understood. Here the authors reveal a set of cephalopod-restricted rearranged genomic loci, involving known neuronal regulators but also unexpected gene families, that confer topological organization and gene regulation.
