Polytene chromosomes normal.
A posterior clone runs along the antero-posterior boundary until it reaches a gap in wing vein 4 (a region sensitive to lack of dpp) where the border of the clone becomes irregular.
dpps4/dpps8 is a suppressor of wing vein | ectopic phenotype of Ras64BAct5C.PC
The dpp shortvein phenotype is strongly enhanced, and the tkv phenotype is suppressed, in dpps4 tkv1/dpps8 tkv8 double mutant flies. The rhohs.PSt and Ras64BAct5C.PC ectopic vein phenotypes are suppressed in combination with dpps4/dpps8. dpps4/dpps8 NAx-1 double mutant flies show pronounced wing vein loss. The dpp loss of vein phenotype is epistatic in dpps4/dpps8 Nnd-3 double mutants, and the vein thickening characteristic of Nnd-3 is eliminated.
