Fig. 2. The expression of dibeta in wing discs causes a dominant-negative effect and produces wing blisters. (A) Adults hemizygous for a viable hypomorphic mys allele, mysB43 do not develop wing blisters. (B) Expression of dibeta in the whole wing disc using the CY2 GAL4 line causes a wing blister phenotype to develop in the adult. (C) Wing blistering induced by dibeta overexpression is enhanced in an integrin mutant background, mysB43 (compare bubble in C with that in B). This enhancement is quantified in D.
