UAS sequences regulate expression of an RNAi line that targets Su(var)3-3.
FlyBase curator comment: this entry represents a transgenic construct where the particular construct used cannot be determined.
Expression of Su(var)3-3VDRC.cUa under the control of Scer\GAL469B results in the formation of ectopic veins anterior to the L2 vein and along the posterior crossvein.
Expression of Su(var)3-3VDRC.cUa under the control of Scer\GAL4bs.PU results in ectopic vein formation including an ectopic anterior crossvein in a small percentage of animals.
