Phylogenetic analysis of CYP78A genes. A phylogenetic tree of 38 protein sequences of CYP78A from different species was constructed with MEGA5. Abbreviated species names are given before gene identifiers: Aegilops tauschii (Aet), A. thaliana (Ath), B. distachyon (Bd), H. vulgare (Hv), Oryza sativa (Os), T. urartu (Tu), Zea mays (Zm). Gene names are given after identifiers if available. The CYP75B1 gene TT7 of A. thaliana was used as an outgroup. The bootstrap method was applied to test for statistical significance of branches. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1,000 replicates) is shown next to the branches. Branches with insufficient bootstrap support (<50%) were collapsed to obtain a consensus tree.
