The phylogeny of lepidopteran PRs.
The Maximum Likelihood tree with functionally identified lepidopteran PR sequences and ObruOR1 orthologues. The tree is rooted with Orco lineage. Percentage bootstrap support (100 replicates) values over 50 are shown at corresponding nodes. ObruOR1 and Obru\Orco are indicated with arrowheads. The ω values (ratio of nonsynonymous to synonymous substitutions, dN/dS) are shown in the tree. *Orthologous Cluster II, III and IV have a uniform ω rate for all branches, whereas Cluster I has various ω rates for all branches within the lineage.
