UAS sequences regulate expression of three shRNAs; one that targets abd-A (this hairpin contains an inverted repeat of ATGGATATGCTTACAGATTAA), one that targets (this hairpin contains an inverted repeat of CCGCAAGCACATGTTCGCCTA) and one that targets Ubx (this hairpin contains an inverted repeat of CAGGTAAGAGATACTCAGAAT).
