Fig. 3.

AOX and XDH genes in fishes, amphibians, reptiles, and birds. The figure shows a schematic representation of the AOX and XDH genes in the indicated vertebrates for which complete or almost complete genomic sequence data are available. Orthologous and predicted precursor genes are indicated with the same color. Predicted AOX pseudogenes are crossed through and asterisked. The number of exons in the active AOX genes are indicated along with the exons identified in the AOX pseudogenes. Dashed boxes are used when the length of the genes is unknown. Dashed lines are used when the intragenic distances are undetermined. When available, the chromosomal location is shown on the right. The simplified rooted phylogenetic diagram on the left illustrates the relative evolutionary distance between the lineages the animal species analyzed belong to. The Latin names of each species are followed by the corresponding common names in parenthesis
