Response to quinine is modulated by feeding status.

<p>The response of wild-type animals to dilute quinine diminishes upon food deprivation (p < 0.00001 for 2.5 mM when comparing animals assayed “off food” versus “on food”). The percentage of animals responding is shown. The combined data of n ≥ 60 animals is shown for each concentration. Animals were assayed 10–20 minutes after transfer to plates with or without food (no bacterial lawn). conc = concentration. n.s. = not significant. WT = the N2 wild-type strain.
