Fig. 3. Cell behavior upon entering or leaving acetate. The data from Fig. 2 were transformed into differences between the control value and experimental value for on- and off-response PDCs (A) and on-response speed in mm s^-1 (B). (C) The T-maze values for wild type and mutants in A and B. (Values >0.5 indicate attraction, <0.5 indicate repulsion.) Arrow indicates significant difference with wild type at P<0.01, Mann-Whitney U-test.
