Cytology
Description

The R25B02 enhancer fragment is fused upstream of the Drosophila synthetic core promoter (DSCP) followed by the GAL4(DBD)::Zip- hemidriver (component of the 'Split GAL4' system, contains the GAL4 DNA-binding domain). An Hsp70 transcriptional terminator is present.

      Activation of C2 lamina neurons, using Hsap\RELAAD.R20C11.T:Zzzz\Zip+, Scer\GAL4DBD.R25B02.T:Zzzz\Zip- and TrpA1Scer\UAS.cUa, increases steering responses to regressive motion and decreases responses to progressive motion.

      Silencing of C2 lamina neurons, using Hsap\RELAAD.R20C11.T:Zzzz\Zip+, Scer\GAL4DBD.R25B02.T:Zzzz\Zip- and Hsap\KCNJ2Scer\UAS.T:Avic\GFP-EGFP, abolishes reverse-optomotor inversion at high speeds.

      Silencing of C2 lamina neurons, using Hsap\RELAAD.R20C11.T:Zzzz\Zip+, Scer\GAL4DBD.R25B02.T:Zzzz\Zip- and Hsap\KCNJ2Scer\UAS.T:Avic\GFP-EGFP, affects the ability of flies to distinguish small contrast differences at low test speeds, while behaviour at higher test speeds remains normal.
