Proton signaling, but not the execution of the pBoc in and of itself, promotes backward motion during the DMP cycle.
(a) The fractions of detected single, double and multiple body-length troughs during the L4 stage of pbo-4 and pbo-5 pBoc deficient mutants. (b) Baseline propensities (empty bars, measured 20–25 sec prior to the aBoc) and peak DAMP propensities (solid bars) for backward motion of wild-type (data reproduced from Fig. 4), pbo-4 and pbo-5 mutants. (c) The absolute anterior angles during DMP cycles in which backward motion was detected (solid bars) or not detected (empty bars) for wild-type animals (data reproduced from Fig. 4), pbo-4 and pbo-5 mutants. N(wild-type) = 28, N(pbo-4(n2658)) = 11, N(pbo-4(ok583)) = 13, N(pbo-5(ox4)) = 13 and N(pbo-5(n2303)) = 10. Error bars depict ± s.e.m. Single and double asterisks denote significant differences from wild-type (p < 0.05 and p < 0.01, respectively).
