Evolution of the Genome 3D Organization: Comparison of Fused and Segregated Globin Gene Clusters.

The genomes are folded in a complex three-dimensional (3D) structure. Some features of this organization are common for all eukaryotes, but little is known about its evolution. Here, we have studied the 3D organization and regulation of zebrafish globin gene domain and compared its organization and regulation with those of other vertebrate species.
