Segmental chromatin states

We profiled the chromatin accessibility, transcription factor binding, and gene expression in the homologous wing and haltere imaginal disc of Drosophila melanogaster, which are distinguished by the expression of the Hox protein Ultrabithorax (Ubx). Through the analysis of chromatin changes, we show Ubx has widespread effects on the chromatin landscape to specify cell identity.
