FIGURE 2

Maximum-likelihood tree of ORs from P. saucia and other Lepidoptera. The tree was rooted by the conservative ORco gene orthologs. Branches of the ORco clade are highlighted with green; branches containing “lepidopteran PRs” are highlighted with blue. Candidate PsauORs are colored with red letters. Node support was estimated with 1000 bootstrap replicates, and bootstrap values were displayed with circles at the branch nodes based on the scale indicated at the top left. The scale bar at the lower right indicates the branch length in proportion to amino acid substitutions per site. Psau, P. saucia; Harm, H. armigera; Bmor, B. mori.
