Fig 1. Unconstrained Nrf2 Bayesian phylogenetic tree and species tree.

Fig 1

(A) Unconstrained Bayesian phylogenetic tree based on Nrf2 coding sequences, under the GTR+G model. Values on the nodes are posterior probabilities. (B) Species tree of the 21 mammals used in this study based on their accepted relationships. Four branches tested by the two-ratio model tests and the branch-site model tests are marked as A, B, C, and D. The four species with orange labels are Old World fruit bats. The seven amino acid substitutions specific to Old World fruit bats are shown (A100D, N133D, D205F, D224G, T279I, T350R and N424S).
