CK1-γ/gish and Rab11 genetically interact during trichome formation. (A) Strong expression of constitutively activated en-Gal4 UAS-YFP-Rab11^CA (29°C) resulted in multiple trichomes in adult wings. (B and C) UAS-YFP-Rab11^CA expression at 25°C via en-Gal4 exhibited no phenotype (B), whereas a single allele of gish^e01759 induced multiple trichomes (C). (D and E) The en-Gal4 UAS-gish^IR phenotype was synergistically enhanced by coexpression of UAS-GFP-Rab11^CA at 25°C. Distal is to the right in the images. (F) The quantification of results from B–E is represented. Error bars indicate SDs; unpaired t test was performed on three independent animals (*, P < 0.05). Bars, 25 µm.
