Figure 3From: The evolution of paralogous enzymes MAT and MATX within the Euglenida and beyondSchematic trees illustrating two possible scenarios of MAT/MATX evolution mapped on the currently accepted phylogenetic relationships of euglenids. The presence of MATX is marked with orange color and MAT is colored with black. (A) Scenario involving deep paralogy followed by differential losses. (B) Scenario involving horizontal gene transfer.Back to article page
