mca-3 is required for touch sensitivity. (A) mca-3p::gfp is expressed in the TRNs. The white arrows mark the ALM and PLM cells. (B) Anterior (left) and posterior (right) touch sensitivity of mca-3 animals with or without mec-3p::mca-3(+) (TRN::mca-3c). Individual data points mark mean response from a plate of animals. Means and SEMs of the individual data points are also shown. *P < 0.05, and **P < 0.001. N ≥ 3. (C) Maximum calcium response elicited by touch in wild-type and mca-3 animals, as detected by relative changes in GCaMP3 fluorescence. Individual data points as well as the means and SEMs are shown. n ≥ 7. **P < 0.001.
