Effects of Fmi on the growth of C4da axon terminals. a Images of V axon terminals. b, c fmi mutations lead to shortening of axon terminals and an increase in the number of branches of V neurons. Overexpression of Fmi leads to excessive growth of axon terminals and an increase in the number of branches. dTrim9 partially rescues the phenotypes caused by fmi dysfunction. *P < 0.05; **P < 0.01; ***P < 0.001; WT: n = 22; fmi^E59: n = 20; fmi^E59 + OE dTrim9: n = 19; OE Fmi: n = 20; dTrim9−/− + OE Fmi: n = 18
