From: Hox cluster characterization of Banna caecilian (Ichthyophis bannanicus) provides hints for slow evolution of its genome

Fig. 1

Genomic organization of the Hox clusters in Banna caecilian and Western clawed frog. Schematic representations of the HoxA, HoxB, HoxC and HoxD clusters in caecilian are shown, with the frog Hox clusters drawn for comparison. For each Hox cluster, location of the genes, repetitive sequences and conserved noncoding elements are separately illustrated from top to bottom. Total numbers of the repetitive sequences and conserved noncoding elements are indicated at the end of each cluster. Exons of the genes are characterized by black bars and pseudogenes are denoted by the symbol Ψ. Gaps in the intergenic regions are indicated by dotted lines. Repetitive sequences identified by Censor are represented by grey bars. Conserved noncoding sequences predicted using mVISTA are classified into 4 phylogenetic groups (see Methods for details): “gnathostome (blue bars)”, “osteichthyan (green bars)”, “sarcopterygian (red bars)” and “tetrapod (orange bars)”. For clarity, CNEs conserved in caecilian and frog only are not shown in the figure
