UASt regulatory sequences drive expression of an inverted repeat of nucleotides 2604-3503 of a wts cDNA, with each copy of the repeated sequence being separated from the other by an artificial intron sequence from the vn gene.
Scer\GAL4Myo31DF-NP0001-mediated expression of wtsdsRNA.Scer\UAS does not alter the morphology or timing of midgut degradation.
Expression of wtsdsRNA.Scer\UAS under the control of Scer\GAL4en-e16E results in tumours and organ size enlargement.
