Ammonium-Acetate Is Sensed by Gustatory and Olfactory Neurons in Caenorhabditis elegans
(A) Water soluble chemotaxis assays. Chemotaxis index is plotted vs. strain for assays in which radial gradients of NH4Ac were established by diffusion in the agar. (B) Odorant NH4Ac assays. Chemotaxis index is plotted vs. strain for assays in which a droplet of NH4Ac (10 µL, 7.5 M) was suspended from the lid of the plate. In A and B, each bar represents the mean of at least 8 independent assays; n.d. means no data. Wild type (neg. con) is a negative control assay with no attractant on plate. Statistics: * p<0.05 and ** p<0.01 in a one way ANOVA and Dunnet's post test comparing all means to the wild-type (N2) mean; # p<0.05 in a one-way ANOVA with Dunnet's post test comparing che-2(e1033), che-3(e1124), and osm-3(p802) to the negative control.
