Expression of WASpΔA.Scer\UAS in the mesoderm under the control of Scer\GAL4twi.PG results in myoblast fusion defects. Small multi-nucleated muscles form, and there are large gaps between the muscles. Fusion rounds appear to stop after precursor formation.
WASpΔA.UAS/Scer\GAL4arm.PS partially rescues Df(3R)3450/WASp1
The addition of WASpΔCA.Scer\UAS driven by Scer\GAL4arm.PS, partially rescues the bristle phenotype seen in WASp1/Df(3R)3450 adults, though fails to rescue the lethality phenotype.
