Early histone acetylation is enriched around loci that require Zld for chromatin accessibility. (A,B) Distribution of ChIP-seq signals for H3K18ac (A) and H4K8ac (B) surrounding individual classes of FAIRE peaks at specific nuclear cycles during the early stages of embryonic development. Colors indicate the different FAIRE classes. Plots are centered on the FAIRE peak and oriented relative to the transcription start site of the nearest gene.
