UAS regulatory sequences drive expression of a 497bp inverted repeat of kn, which is separated by a w intron.
wing vein L3, with Scer\GAL4ap-md544
wing vein L4, with Scer\GAL4ap-md544
Expression of kndsRNA.Scer\UAS under the control of Scer\GAL4ap-md544 results in wings which have a clear L3-L4 vein fusion.
Expression of kndsRNA.Scer\UAS produces dsRNA which results in dsRNA interference (RNAi) of the kn gene.
