Promotion of food consumption by dietary amino acids. a Schematic illustration of the MAFE assay. b Volume of 400 mM sucrose (grey) or 400 mM sucrose plus different concentrations of amino acid mixture (blue) consumed by Canton-S virgin females fed ad libitum (n = 21–59). The composition of the amino acid mixture is shown in Supplementary information, Table S1.20 c Fractions of Canton-S virgin females showing PER responses to sucrose alone (grey) or sucrose plus different concentrations of amino acid mixture (blue) (n = 38–40). d Feeding duration of Canton-S virgin flies when fed with sucrose alone (grey) or sucrose plus amino acid mixture (blue) (n = 20). e Volume of water consumption in the presence or absence of 5 mM amino acid mixture by water-deprived Canton-S virgin females (n = 28–32). f Volume of sucrose solution consumed by Canton-S virgin females, in the presence or absence of 5% yeast extract (n = 17–18). g, h Volume of food consumed by mated Canton-S females (g) or males (h) fed ad libitum (n = 18–24). Symbols indicate the type of flies used in each experiment (virgin females, mated females, or males). Data are shown as means ± SEM. NS, P > 0.05; *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001
