Phylogenetic relationships of MYBs in other plants compared to the four MYBs from the chrysanthemum. Full-length amino acid sequences of MYBs from all species were first aligned using ClustalW in MEGA. The phylogenetic tree was constructed according to the neighbor-joining method. Branches corresponding to partitions reproduced in less than 50% of the bootstrap replicates were collapsed. The evolutionary distances were computed using the p-distance method. All ambiguous positions were removed for each sequence pair. Stars represent the four CmMYB proteins. S represents subgroup. The GenBank accession numbers of each species are shown in Supplementary Table S1.
