Frizzled and flamingo mediates Wg signal to regulate dendrite directional growth in ddaE neuron. a-d Knockdown of fz in wg ^spd-fg mutant background rescues the PD-Angle to wild type level, while knockdown of fz in wg ^l-12 mutant background does not further decrease the PD-Angle. (n = 25-45). e-h Knockdown of fmi in a wg ^spd-fg or wg ^l-12 mutant background does not further decrease the PD-Angle. (n = 26-44). Red arrows indicate the initial parts of primary dendrites.
