Identifications of vernalization regulatory elements by epigenomic approaches in winter wheat (ChIP-Seq)
Epigenetic modification plays a key role in the vernalization process and maintains gene expression states after low temperature. In this study, the Chinese main cultivar Aikang58 was used to construct the chromatin accessibility maps, expression profile and histone modification (including H3K27me3, H3K27ac, H3K36me3 and H3K4me3) maps of winter wheat before and after vernalization.  We provided a crucial data resource for deep understanding of epigenome in vernalization. What's more, important core regulatory elements and corresponding transcription factors were discovered, and the complex regulatory network of wheat vernalization was analyzed. Overall design: ChIP-seq of leaf and vernalized leaf, including H3K27me3, H3K27ac, H3K36me3 and H3K4me3
