Phylogeny of the cellulose synthase family in land plants. A phylogenetic tree built using maximum likelihood by the program PhyML on the alignment of the CesA family. The phylogeny shows that the CesA family is divided into clades which correspond to the required CesAs in Arabidopsis. The clades are labeled based on their similarity to the identified Arabidopsis CesA. Numbers reported represent bootstrap values with 100 total bootstraps run. Organism abbreviations are listed in Table 1.
