Distribution of histone modifications in the rRNA gene repeat of L. major. The promoter region (arrow) is enriched with H3K9me3, H3K14ac, H3K23ac and H3K27ac [87]. The distribution of H4K20me3 is also indicated. 63-bp repeats are present in the intergenic spacers. The relative position of nucleosomes along the rRNA genes is indicated at the top of the figure [87].
