Fig. 7

Location of putative enhancers of the the DRx gene driving expression at different developmental stages. The genomic organization of the DRx locus is shown together with the location of fragments from the upstream and intronic regions of the DRx locus used to test enhancer activities in the respective Gal4 strains. Above the genomic organization are the locations of the different putative DRx enhancers indicated as grey boxes at different developmental stages in the embryonic brain (E), larval brain (L) and adult brain (A). For the DRx enhancers in the brain the specific expression domains are indicated according to Figs. 4, 5 and 6. Abbreviations: CL, clypeolabrum; CP, clypeus; DAL, dorsal anterior lateral; DAM, dorsal anterior medial; dIPC, dorsal inner proliferation centre; DL, dorsolateral lineages; DM, dorsomedial lineages; DPLc, dorsal central lateral; DPM, dorsal posterior medial; LD, lateral domain; LH, lateral horn; LP, lobula plate; M, medulla; MB, mushroom body; OTU, optic tubercle; PB, protocerebral bridge; PLP, posterior-lateral protocerebrum; VLP, ventro-lateral protocerebrum
