Deletion of exon 1 of Wnt6.
Homozygous Wnt6KO flies are viable and fertile and have no obvious defects in wing size. The wing margin appears intact, and there is no obvious planar cell polarity phenotype.
Homozygous Wnt6KO flies completely lack maxillary palps.
Expression of Wnt6Scer\UAS.cDa under the control of Scer\GAL4elav.PU rescues maxillary palp formation in Wnt6KO mutants, but the ectopic expression driven by Scer\GAL4elav.PU results in morphological defects, such as small heads and glazed eyes.
The spacing of chemosensory bristles in Wnt6KO wings tends to be less precisely specified, with reduced average distance and a broader spacing distribution, compared with controls.
Wnt6KO is rescued by Wnt6UAS.cDa/Scer\GAL4elav.PU
