UAS regulatory sequences drive expression of dl coding sequences.
dlUAS.cCa/Scer\GAL4VP16.mat.αTub67C rescues Df(2L)TW119/dl5
Expression of dlScer\UAS.cCa under the control of Scer\GAL4mat.alphaTub67C.T:Hsim\VP16 completely suppresses the dl5/Df(2L)TW119 phenotype, sometimes even to the point of ventralisation.
