A 2140 base pair fragment from the flanking non-coding or intronic region of fru is fused upstream of a Drosophila synthetic core promoter (DSCP) followed by sequence encoding a GAL4 driver.
A FLP/FRT intersectional strategy shows expression of ScerGAL4VT043656 in 15-30 fruitless-expressing lobula columnar neuron LC10a neurons when combined with ScerFLP1fru.
