Chromatin accessibility in salivary gland nuclei depleted for Su(H) by RNAi, measured by ATAC-qPCR; fold enrichment at the indicated regions compared to a "closed ctrl" region. Accessibility is increased across most of the E(spl)-C compared to controls expressing LacZ. Control primer regions are as in B and C. Mean +/- SEM; n = 3; * p<0.05 with two-tailed Welch's t-test compared to LacZ controls.
