Fig. 2From: Identification of the genes involved in odorant reception and detection in the palm weevil Rhynchophorus ferrugineus, an important quarantine pest, by antennal transcriptome analysisMaximum likelihood (ML) tree of the odorant binding protein (OBP). Bombyx mori OBPs [50] were used as reference to classify the R. ferrugineus OBPs and the ML analysis was computed using MEGA (v.6.0) [42] (JTT model for ML heuristic searches methods was Nearest-Neighbor-Interchange). The coleopteran OBPs; T. castaneum OBPs, D. ponderosae and I. typographus [25] were also used to construct the tree with R. ferrugineus OBPs. R. ferrugineus OBPs transcripts and node are marked with red color. R. ferrugineus OBPs putatively identified are highlighted. GenBank accession numbers are indicated.
