UAS regulatory sequences drive expression of a short inverted repeat.
The expression of brwlGL00521 under the control of Scer\GAL4VP16.nos.UTR or Scer\GAL4VP16.mat.αTub67C, but not of Scer\GAL4C587, leads to an array of highly prevalent and progressive ovary defects, including ovariole architecture defects, fused egg chambers, picnotic nuclei and degenerated egg chambers, as compared to controls.
