Out of the 12 promoters, 8 drove expression in the XXX cells at various levels (
asic-1,
dhs-17, F14H8.2, C06A1.3,
asp-9, B0034.5, F52E1.5, and
nlp-15), one was impossible to score (T22E5.6) because it also drove high expression in the pharynx located very close to the XXX cells, and three did not show detectable expression in XXX cells (in adults;
mab-9,
twk-39, and
lgc-36).
