Figure 1

(a) Alignment of the five OBPs of V. destructor. The six conserved cysteines are highlighted. VdesOBP1 and VdesOBP2 are very similar (72% identity), as VdesOBP3 and VdesOBP4 (60%), but proteins of the two groups share only about 15% of their residues between them as well as with VdesOBP5. The six conserved cysteines are highlighted and in red font. Signal peptides are underlined. (b) Phylogenetic tree of tick and mite OBPs. Vdes: Varroa destructor; Turt: Tetranychus urticae; Hqin: Haemaphysalis qinghaiensis; Hfla: Haemaphysalis flava; Hlon: Haemaphysalis longicornis; Isca: Ixodes scapularis; Gocc: Galendromus occidentalis; Tmer: Tropilaelaps mercedesae; Rann: Rhipicephalus annulatus; Rsan: Rhipicephalus sanguineus; Ldel: Leptotrombidium delicense; Dtin: Dinothrombium tinctorium; Dpte: Dermatophagoides pteronyssinus; Ssca: Sarcoptes scabiei; Emay: Euroglyphus maynei. All sequences used to build the tree are reported in Supplementary Table S1 online. Names of ticks are in red, those of mites are in green. Highlighted clades contain VdesOBP1 and VdesOBP2 (pink), VdesOBP3 and VdesOBP4 (light blue), VdesOBP5 (light green).
