The RMCE cassette of the Mi{MIC}drdMI15121 insertion has been replaced with a Trojan-GAL4 cassette. This disrupts the drd gene and results in expression of GAL4 under the control of endogenous drd regulatory sequences.
drdMI15121-TG4.1/+ adults lack a peritrophic membrane in the midgut.
drdMI15121-TG4.1 is rescued by drdUAS.cCa/Scer\GAL4drd-MI15121-TG4.1
Expressing drdUAS.cCa under the control of Scer\GAL4drd-MI15121-TG4.1 (the intrinsic Gal4 driver of drdMI15121-TG4.1) rescues adult mortality and peritrophic membrane formation in drdMI15121-TG4.1/drdMI15121-TG4.1 flies.
Expressing drdUAS.cSa under the control of Scer\GAL4drd-MI15121-TG4.1 (the intrinsic Gal4 driver of drdMI15121-TG4.1) rescues adult mortality in drdMI15121-TG4.1/drdlwf flies.
