Figure 1.Expression pattern produced by Geneswitch drivers and UAS-GFP reporter in adult flies. The indicated GeneSwitch
drivers Act-GS-255B ("255B"), Elav-GS ("Elav") and WB-FB-GS ("FB") were
crossed to the UAS-ultraGFP reporter and adult progeny containing both
constructs were scored for GFP expression in various tissues. Control
flies were generated by crossing UAS-ultraGFP to white1118strain flies to produce progeny containing only UAS-ultraGFP. Age-synchronized
flies were cultured in the presence and absence
of the drug RU486 for two weeks prior to assay, and GFP expression was
scored in whole adult flies and dissected tissues, as indicated. Each
image is the overlay of the visible light and GFP images. Insets show
details of the regions boxed in white, GFP image only. M = male, F =
female. Pictures were taken at the magnification of 20X, 50X, 32X, 20X,
50X, and 80X, for whole fly, head in half, body in half, gut, ovary, and
testes, respectively. The white arrow indicates a region of 255B Female
flight muscle that is obscured by a fragment of cuticle.
