Figure 1. Evidence of the loss of the DAT gene in the vertebrate lineage containing birds and reptiles (i.e. sauropsids).

Figure 1

(a) Schematic representation of conserved chromosomal loci that contain DAT in representative mammalian species. (b–d) Lack of the DAT gene in this same conserved region in chicken (b), representative neoaves (c) and reptilian (d) species. (e) The DAT gene is found in representative non-sauropsid species, including fish, amphibians and non-eutherian mammals. In a-e, the position of the DAT gene is indicated in red, flanking syntenic genes in black, and missing DAT orthologs by a blue “X”. (e) Schematic tree (unscaled) depicting the phylogenetic relationships among representative species of the major tetrapod lineages. Major branches that have retained the DAT gene are indicated in red, those that have lost the DAT gene are indicated in blue.
