UASt regulatory sequences drive expression of an inverted repeat.
The expression of quaKK103765 under the control of Scer\GAL4hh-Gal4 or Scer\GAL4ap-md544 induces a small wing disc pouch, as well as fewer and shortened/misshapen in microvilli in the wing disc posterior compartment. In the Scer\GAL4hh-Gal4-driven expression condition, wing discs show a decrease in the number of extracellular vesicle; adults show a small wing.
