A 3871 base pair fragment from the flanking non-coding or intronic region of pdm2 is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
Optogenetic activation (using Crei\ChR2UAS.cSa with 470 nm (blue) light) of Scer\GAL4GMR11F05 cells in larvae results in a significant increase in turning behaviors, compared to controls.
