Characterization of the 9-ODA receptor, AmOr11 + AmOr2. (A) An oocyte expressing AmOr11 + AmOr2 is challenged with a range of 9-ODA concentrations. (B) Dose–response relationship for 9-ODA activation of AmOr11 + AmOr2 (EC₅₀ = 280 ± 31 nM, mean ± SEM, n = 10). (C) An oocyte expressing AmOr11 + AmOr2 responds to 100 μM 9-ODA but not to 100 μM methyl oleate (MO), linolenic acid (LA), coniferyl alcohol (CA), or 1-hexadecanol (HD). (D) An oocyte expressing AmOr11 + AmOr2 responds to 100 μM 9-ODA but not to 100 μM hexanol (HEX), linalool (LIN), geraniol (GER), or citral (CIT). All applications were 25 s and are indicated by arrowheads (A, C, and D).
