UAS regulatory sequences drive expression of a 2.1kb XhoI fragment of the drm EST LD26791.
lethal, with Scer\GAL4byn-Gal4
embryonic hindgut, with Scer\GAL4byn-Gal4
Embryos expressing drmEST.Scer\UAS under the control of Scer\GAL4byn-Gal4 have a short, distended hindgut, which consists of a uniform layer of cuboidal cells (similar to the wild-type small intestine). The boundary cell rows are absent.
