UASt regulatory sequences drive expression of an inverted repeat.
Adulthood-only expression of Ae2GD2397 driven by Scer\GAL4109-30 (and temporally regulated by Gal80[ts] and temperature shift from 18po]C to 25[o]) leads to enlarged basal stalks in the ovary; a milder phenotype is also observed in the absence of driver.
Scer\GAL4mex1.2.1-mediated expression (in midgut) has no detectable effect on larva viability.
