Figure 2: Dependence of L-canavanine induced action potentials on Gr98b.
From: The full repertoire of Drosophila gustatory receptors for detecting an aversive compound

(a) Action potentials elicited in S6 sensilla of control (w1118), Gr98b1 and rescue flies (Gr66a–GAL4/UAS–Gr98b;Gr98b1) in response to 30 mM L-canavanine. (b) Mean frequencies of action potentials upon exposure to 30 mM L-canavanine. Indicated are the genotypes and sensilla tested (S3, S5 and S10), n=10–12 for each genotype. (c) Mean frequencies of action potential induced in S6 sensilla in response to the indicated bitter chemicals (1 mM PAP, 1 mM STR, 1 mM DEN, 0.1 mM BER, 1 mM LOB, 10 mM CAF, 0.2% DEET and 1 mM QUIN). n=10–21 for each genotype. All data are mean±s.e.m. **P<0.01 (analysis of variance with post hoc Tukey test).
