Figure 7.
Evolutionary conservation. Unrooted phylogenetic tree of selected GAPDH sequences calculated with the maximum-likelihood software PhyML with branch supports shown at every node. Sequences are colored according to taxonomic grouping, with bacteria in yellow, plants and algae in green, yeasts in orange, arthropods in purple, mammals in blue, and protozoa in red. The multiple sequence alignment is provided in the SI. This figure was produced with FigTree (http://tree.bio.ed.ac.uk/software/figtree/).
