Figure 5. Genetic interactions between lqfR and dachsous.

(A-A′″) Confocal microscope images of an eye disc immunostained with antibodies to β-galactosidase are shown. The disc expresses GFP in all cells except for lqfR^Δ117 homozygous clones. The genotype is ds-lacZ/+; FRT82B lqfR^Δ117/FRT82B ubi-gfp. (A′) Clones are outlined. (A″,A″′) Enlargements of part of A′ which shows that ds-lacZ expression levels are lower in lqfR^Δ117 clones than in adjacent wild-type tissue. (B) A light microscope image of an eye from an adult fly hypomorphic for lqfR is shown. (C) The head (dorsal view) of a pupa that will not eclose dissected from its pupal case. ds^38k/ds⁺ animals (not shown) appear wild-type. scale bar: ∼10 µm in A,A′; ∼5 µm in A″, A″′; ∼100 µm in B,C.
