The ZAM sensor transgene is not repressed in the germline of D. melanogaster ovaries. a Structure of the pGFP-ZAM sensor transgene. The UASp promoter contains the Gal4 target sequence upstream of the GFP reporter gene fused to 467 bp of the ZAM env gene (light grey box, sense orientation). The ZAM sequence is flanked by two FRT sites. The arrow indicates the transcription initiation site. b Confocal images of ovarioles after GFP (green, left) and DNA (blue, middle) staining. Ovarioles were from the progeny of a cross between w1118 females and males harboring the pGFP-ZAM transgene driven by the actin-Gal4 driver. Merged images for GFP and DNA labeling are displayed on the right
