Phylogenetic analysis of the CE proteins from B. juncea and other genera. The Neighbor–Joining phylogenetic tree based on the protein alignment was created with MEGA 4.1. The sequences were aligned with Clustal X software, and the scale bar indicates an evolutionary distance of 0.05 amino acid substitution per site. The number at the nodes show bootstrap values (>800) after 1000 replicates. Accession numbers and species names of each gene are shown in Supplementary Table S2 at JXB online.
