Defects in ck/myoVIIA disrupt the morphology and distribution of setae, microchaetae, and macrochaetae on the head and wing and alter the morphology of the aristae. (A) Macrochaetae, microchaetae, and setae near the ocelli on control (A) and ck¹³/Df mutant (A′) flies. Microchaetae are twisted and bent, and micro- and macrochaetae have abnormally deep and irregular grooves. Multiple setae also characterize mutant vs. control flies. Bars in A and A′, 20 μm. (B) Wing hairs on ck¹³/Df mutant (B′) flies show a multiple wing hair (setae) phenotype (vs. control, B). Bar in B′, for B and B′, 20 μm. (C) Aristae on ck¹³/Df mutants (C′) are shorter and more highly branched than controls (C). Bar in C, for C and C′, 100 μm.
