α-Cat is potentially required for circadian locomotor rhythm. (A) Locomotion behavior under light dark (LD) cycles and constant darkness (DD). Representative double plotted actograms showing last 3 days of LD and 5 days of DD for controls, flies that express dsRNA targeting α-Cat (TD2/+; α-Cat RNAi#2/+flies). White indicates the light phase, and gray indicates the dark phase. (B) Effects of α-Cat downregulation in circadian neurons on period length of circadian locomotion behavior. Bar graph showing period length (y axis), percentage of rhythmic flies, and number of flies tested (in the bars). Error bars indicate SEM. Each genotype was compared to appropriate genotype control or driver control. ***p < 0.001; **p < 0.01; *p < 0.05; n.s., not significant at the 0.05 level, tested using Student’s t test.
