A 2928 base pair fragment from the flanking non-coding or intronic region of lilli is fused upstream of a Drosophila core synthetic promoter (DSCP) that is followed by sequence encoding a GAL4 driver.
ScerGAL4GMR44E10 drives expression in follicle cells of mature egg chambers throughout stage S14. ScerGAL4GMR44E10 is not expressed in any tissues in the lower reproductive tract, nor in the neurons innervating the reproductive tract.
