pll7/pll2 and pll7/pll25 larvae show show mistargeting of the R2-R5 photoreceptor axons in the developing visual system; thickened bundles of axons along the entire length of the lamina are observed to penetrate into the medulla, while the lamina is not smooth and is somewhat irregular.
dppHin embryos derived from pll7 mothers have a dorsalizing phenotype: dorsal setae covering the entire body, rudimentary posterior spiracles lacking Filzkorper and numerous ventral like setae. Individuals have an elongated and convoluted appearance.
The variable dorsalized embryonic phenotype of wekEX14 mutants is enhanced by pll7. While 51% of wekEX14 embryos show an extreme dorsalized phenotype, this penetrance is increased to 92% in wekEX14; pll7/+ embryos.
