The cross-talk between DNA methylation and Polycomb-dependent H3K27me3 histone mark has been reported in a number of organisms [1], [2], [3], [4], [5], [6], [7] and both marks are known to be required for proper developmental progression. Here we provide genome-wide DNA methylation (MethylCap-seq) and H3K27me3 (ChIP-seq) maps for three stages (dome, 24 hpf and 48 hpf) of zebrafish (Danio rerio) embryogenesis, as well as all analytical and methodological details associated with the generation of this dataset. We observe a strong antagonism between the two epigenetic marks present in CpG islands and their compatibility throughout the bulk of the genome, as previously reported in mammalian ESC lines (Brinkman et al., 2012).
