UAS regulatory sequences drive expression of an inverted repeat of 638bp from the nonC gene, which are separated from each other by a "hinge" of 178bp (which is derived from an intron of the Ace gene).
chemical resistant, with Scer\GAL4αTub84B.PL
Flies expressing Smg1dsRNAi.Scer\UAS under the control of Scer\GAL4αTub84B.PL are 1.8 fold more resistant to cyromazine than controls.
