Fig. 8From: Genome-wide MNase hypersensitivity assay unveils distinct classes of open chromatin associated with H3K27me3 and DNA methylation in Arabidopsis thalianaDiagram of enzyme digestion at regions associated with different classes of open chromatin. Regulatory proteins located in “repressive” open chromatin showed a relatively narrow open space and can only be accessed to MNase, but not to DNase I or Tn5Back to article page
