Phylogenetic relationship among class B genes. The neighbor-joining tree was generated based on amino acid sequences with coding regions of class B genes, and 10,000 bootstrap samples were generated to assess support for the relationships. TfDEF and TfGLO were classified into euAP3 and GLO/PI families, respectively. Origins and accession numbers of each protein used here are described in Supplementary Table S1. Local bootstrap probabilities (in percentages) are indicated near the branching points, and values below 50 are omitted
