Genome-wide MNase hypersensitive sites in soybean. Genome-wide MNase hypersensitive sites in soybean

We investigated MNase hypersensitive sites (MHSs) in four soybean tissues (leaf, flower, seed and root) by MH-seq. The MHSs were highly overlapped with ATAC-seq peaks from previous study. In addition, we detected many MHSs, which is not identified by ATAC-seq. Through comparing MHSs among three tissues, we identified tissue-specific MHSs, which contributed to tissue specific expression of their cognate genes. As analyzing MHSs between duplicated genes, we found the divergence of MHSs between duplicated genes were highly related with their gene expression divergence. Overall design: Chromatin are lightly digested by MNase to identify open chromatin regions in soybean.
