A phylogenetic tree of the endo-(1,4)-β-glucanases of cereals and Arabidopsis. Included on this tree are barley (blue), maize (green), rice (purple), sorghum (tan), Brachypodium (black) and Arabidopsis (red). Clades of interest as specified in the text are circled in grey. The bar at the bottom provides a relative measure of branch length. The tree was produced from the Geneious tree builder module of the Geneious Pro 5.6.5 software package (Biomatters Ltd. Level 2 76 Anzac Avenue Auckland 1010 New Zealand) using the nearest neighbor joining method with 1000 replicates to obtain bootstrap values. Clade branches are labeled with % consensus support. The tree was annotated in Treeview .
