Fig. 1From: Molecular evolution of Odorant-binding proteins gene family in two closely related Anastrepha fruit fliesMid-point rooted ML phylogenetic relationships of the OBPs. The branches are color coded for each subfamily: classic (blue), minus-C (green), plus-C (red) and dimer (purple). Branch lengths are estimated by amino acid substitutions per site. Brown and underlined numbers represent the SHlike aLRT branch supports for the four subfamiliesBack to article page
