From: History of a prolific family: the Hes/Hey-related genes of the annelid Platynereis
Genomic clustering of the Hes superfamily genes in diverse metazoan representatives. Blue dots correspond to Hes/Hey-related genes (name mentioned above); orange squares represent non-Hes/Hey-related intervening genes; grey dots indicate non-Hes E(spl) members (name mentioned above), green lines represent microRNA. Boxes follow the same color code as in phylogenetic trees (Figures 2 and 3): cnidarians are in blue, lophotrochozoans are in purple, ecdysozoans are in orange and deuterostomians are in green. Physical linkages between Hes/Hey-related genes are found in each of these major lineages, with two to six clustered genes.
