Personal communication from: Matthew Freeman, MRC Laboratory of Molecular Biology To: Bloomington Drosophila Stock Center Subject: GMR-GAL4 Background: Transposon insertion now at Bloomington but not in FlyBase. Information communicated: Freeman, M. (1996). Reiterative use of the EGF receptor triggers differentiation of all cell types in the Drosophila eye. Cell, in press. Symbol used by donor Pw<up>+, GMR-Gal4 #12</up> Map location chromosome 2 Phenotype Gal4 is driven by the glass enhancer, and is the strongest way of expressing things behind the furrow in the eye disc. Other info from donor: The GMR-Gal4 line we made by cloning the Gal4 gene into pGMR1 (made in Gerry Rubin's lab). Most transformant lines had rough eyes, even as heterozygotes, but line 12 is smooth-eyed when heterozygous and grown at 25o or below.
