Drives expression in presumptive distal structures in imaginal discs, including the presumptive tarsal segments of leg discs, the presumptive wing margin, the presumptive second and third segments and arista of the antennal disc, and distal structures of male and female genital discs.
staining shows that the Gal4 driver faithfully recapitulates Dll
expression with two exceptions: (1) the embryonic ventral nerve cord glia that express Dll
expression; and (2) several cells in thebrain that express Dll
, also lack Scer\GAL4Dll-md23
reporter is expressed in a small population of neurons located at the most proximal part of the outer optic lobe (neurons generated by the oldest neuroblasts to have emerged from the neuroepithelium) but not in the neuroblasts themselves. Expression persists in pupae.
Larval expression is observed in the genital and anal primordia of the male and female genital discs. Adult expression is observed in the vaginal plates in females, in the claspers in males, and in the anal plates of both sexes.
Assayed in adult cuticle using y+
marker. Expressed in distal portions of leg, wing, and antenna; expression in femur relatively weak.
Expression in distal portions of leg and antenna; along dorsal/ventral boundary of wing. Observed as adult y+ phenotype; expression assumed to be earlier.
