Genome-wide nucleosome positioning is orchestrated by genomic regions associated with DNase I hypersensitivity in rice. [PDF]
PLoS Genetics, 2014 Nucleosome positioning dictates the DNA accessibility for regulatory proteins, and thus is critical for gene expression and regulation. It has been well documented that only a subset of nucleosomes are reproducibly positioned in eukaryotic genomes.
