Arabidopsis chromatin states

We collected 216 Arabidopsis epigenomic datasets, including ChIP-seq, DNase-seq, ATAC-seq and DNA methylation data. A Hidden Markov Model was applied to aggregate or collapse the multi-dimensional matrices into a small number of chromatin states. We identified 36 chromatin states located in 290,553 segments across the whole genome and different chromatin states contained different epigenetic features.

After chromatin state partition, we employed self-organization mapping (SOM) to integrate, visualize, and mine diverse epigenomic datasets, including 1,350 units that contained different chromatin signatures.
