The following information accompanied stocks donated to the Bloomington Stock Center by Stephanie Gamez and Omar Akbari, University of California at San Diego. M{fln-vanTA.G}, M{fln-cymTA.G}, M{fln-tTA.G}, M{fln-pipTA.G} and M{fln-ttgTA.G} express transcriptional activator proteins under the control of fln regulatory sequences. The constructs are marked with miniwhite (w+mC) and they were inserted into the M{3xP3-RFP.attP'}ZH-86Fa target site at 86E18, 3R:11767433 (R6) to generate the Disc\RFP3xP3.PB-marked insertions M{fln-vanTA.G}ZH-86Fa, M{fln-cymTA.G}ZH-86Fa, M{fln-tTA.G}ZH-86Fa, M{fln-pipTA.G}ZH-86Fa and M{fln-ttgTA.G}ZH-86Fa. Miniwhite-marked (w+mC) responder constructs for these transcriptional activators were generated with the following structure: Activator binding sites-Hsp70 minimal promoter-minimal P element promoter-Firefly luciferase coding sequences-T2A-EGFP-p10 3'UTR-Renilla luciferase coding sequences-Ubi-p63E regulatory sequences and were inserted into the M{3xP3-RFP.attP'}ZH-86Fa target site at 86E18, 3R:11767433 (R6) to generate the Disc\RFP3xP3.PB-marked insertions M{vanO-pLUC.T2A.EGFP,Ubi-rLUC}ZH-86Fa M{cymO-pLUC.T2A.EGFP,Ubi-rLUC}ZH-86Fa M{tetO-pLUC.T2A.EGFP,Ubi-rLUC}ZH-86Fa M{pipO-pLUC.T2A.EGFP,Ubi-rLUC}ZH-86Fa M{ttgO-pLUC.T2A.EGFP,Ubi-rLUC}ZH-86Fa
