Survival of flies following tubP-GAL4-mediated expression of UAS-HDAC constructs.

Each UAS bearing fly strain was crossed to P{tubP–GAL4}LL7/TM3, Sb and the number of Sb and non Sb adult progeny counted for each cross. Sb, stubble bristles.将所有携带UAS（Upstream Activation Sequence）的果蝇品系与P{tubP–GAL4}LL7/TM3, Sb品系进行杂交，并统计每个杂交组合的短刚毛（Sb，stubble bristles）型与非短刚毛型成年子代的数量。Sb即短刚毛（stubble bristles）。
