UASp regulatory sequences are fused upstream of an osk genomic fragment, consisting of the entire osk 3'UTR and about 1kb of the 3' flanking sequences.
osk3'UTR.UASp.cVPa rescues oskA87/Df(3R)p-XT103
Expression of osk3'UTR.attB.Scer\UAS.P\T driven by a combination of Scer\GAL4nos.UTR.T:Hsim\VP16 and Scer\GAL4mat.αTub67C.T:Hsim\VP16 is sufficient to rescue the early oogenesis arrest and egg-less phenotype of oskA87/Df(3R)p-XT103 females.
