Mutant cells in trcS066917a
large clones in the pupal wing often have an irregular shape, and their average cross-sectional area is ~1.6-fold larger than control neighboring cells. Hair morphogenesis is delayed in the trcS066917a
mutants show a multiple wing hair phenotype.
Expression of trcS292A.Scer\UAS
under the control of Scer\GAL4ap-md544
in a trcS066917a
/+ background enhances the multiple wing hair phenotype seen when trcS066917a
is expressed in a wild-type background.
Homozygous second instar larvae have many split denticles per segment.
Hemizygous flies have branched arista laterals.
Homozygous clones have a multiple wing hair phenotype (5.74 hairs/cell).
Mutant cells in homozygous clones in the wing show a strong multiple hair cell phenotype. The number of hairs per cell varies between different clones from an average of 3.5 hairs per cell to more than 7 hairs per cell. Mutant cells in pupal wings have on average a weaker phenotype than clones in adult wings. A substantial number of cells in the clone in pupal wings do not have a multiple wing hair phenotype, in contrast to adult wings. When a wing cell produces a single hair in pupal clones, the hair appears to be the same length as neighbouring wild-type hairs. Only mutant cells show the multiple hair phenotype in pupal wings containing homozygous clones.
