Scer\GAL4how-24B/kirreΔ103-553.UAS.Tag:FLAG fails to rescue Df(1)w67k30
Expression of kirreΔ103-553.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4how-24B does not restore the ability of myoblast founders to attract fusion-competent myoblasts in Df(1)w67k30 mutant embryos; myoblast fusion remains completely disrupted.
Co-expression of kirreΔ610-959.Scer\UAS.T:Zzzz\FLAG and kirreΔ103-553.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4how-24B restores the ability of myoblast founders to attract fusion-competent myoblasts in Df(1)w67k30 mutant embryos. However, myoblast fusion stalls after precursors form.
