Tutl mutant larvae displayed normal locomotion pattern. (A) Free movements of 3rd-instar larvae for three minutes on the surface of 2.5% agarose in 100 mm petri dish were recorded. Green: movements with a speed<1.5 mm/sec; red: movements with a speed>1.5 mm/sec. Arrows indicate examples of turning. (B) Number of contraction waves during a 60-second period were counted (n=10 for each genotype). No significant difference was observed between tutl mutant and w-1118 larvae (p>0.1 for both t-test and one-way ANOVA test). “ns” indicates no significant difference. (C) Average speed during 3-min free larval locomotion was measured. No significant difference in average speed was observed between tutl23/01085 and W-1118 larvae (p>0.1, t-test). Average speed of tutl23/23 larvae was slower than that of W-1118 (*p<0.05, t-test). (D) Number of turnings during 3-min free larval locomotion was analyzed. No significant difference was observed between tutl mutant and w-1118 larvae (p>0.1 for both t-test and one-way ANOVA test). (E) The change in moving direction after turning during 3-min free larval locomotion was measured. No significant difference was observed between tutl mutant and w-1118 larvae (p>0.1 for both t-test and one-way ANOVA test). Error bars represent SEM.
