Ammonium-Acetate Is Sensed by Gustatory and Olfactory Neurons in Caenorhabditis elegans
(A–C) Water soluble chemotaxis assays for NaCl, NH4Cl, and NaAc. In each case, radial gradients of attractant were established by diffusion in the agar. Each bar represents the mean of at least 4 independent assays. Statistics: * p<0.05 and ** p<0.01 in a one-way ANOVA and Dunnet's post test comparing all mutants to the che-1(p679), which serves as a control in that it has normal chemotaxis to NH4Ac but no chemotaxis to NaCl; § p<0.01 in a one sample t-test comparing the observed mean to a mean of zero.
