A cladogram of the plant CesA superfamily and related non-plant proteins. ClustalX (version 1.8) was used to create an alignment of the protein sequences that was then bootstrapped (n = 1000 trials) to create the final tree. Subfamilies are indicated with colored bars on the right. At, Arabidopsis thaliana (thale cress); Gh, Gossypium hirsutum (cotton); Le, Lycopersicon esculentum (tomato); Mt, Medicago truncatula (barrel medic); Os, Oryza sativa (rice); Pt, Populus tremuloides (quaking aspen); Pt/Pa, Populus alba x Populus tremula (gray poplar); Zm, Zea mays (maize).
