Drives expression in abdominal segment 8 (parasegment 13) at all stages; expression is observed in parts of the male and female reproductive systems corresponding to abdominal segment 8.

ScerGAL4Abd-B-LDN drives expression in 283 +/- 10 cells in the adult female abdominal ganglion; these cells are colabeled with Abd-B protein antibodies. ScerGAL4Abd-B-LDN also drives expression in neurons innervating oviducts, uterus, muscles near the female gonopod (vaginal plates), and the gonopod bristles.

ScerGAL4Abd-B-LDN drives expression in the region of the male genital disc corresponding to abdominal segment 8.

ScerGAL4Abd-B-LDN drives embryonic expression in parasegment 13, including tracheal metamere 10.

ScerGAL4Abd-B-LDN marks the ring comprising the anterior compartment of abdominal segment 8 in the male genital disc during pupal development.

ScerGAL4Abd-B-LDN drives expression in the female reproductive system at late pupal and pharate adult stages in the spermathecum, uterus, and female gonopod (vaginal plates), but not in the ovaries, female accessory glands, or oviducts.

ScerGAL4Abd-B-LDN drives expression in the region of the male and female genital discs corresponding to abdominal segment 8.

ScerGAL4Abd-B-LDN expression reflects the distribution of the Abd-B-RB (Abd-B m) transcript. At embryonic stage 15, ScerGAL4Abd-B-LDN expression is localized to two lateral cells in each of the two lateral anterior clusters of 6-7 hdc-expressing cells of the genital disc.
