In the original version of this Article, the y-axis label of Fig. 1d was incorrectly given as “Relative H3Ac/H3 levels” and should read “Relative H4Ac/H3 levels”. In addition, the probe target in the left panel of Figure 1f was misspelled as “Guliver” and should read “Gulliver”. Furthermore, the last label of the diagram on the top of Fig. 2c was given incorrectly as “PF26” and should read “PF25”. Moreover, the label of the branch pointed by the arrow symbol in cluster II of the phylogenetic tree in Fig. 3c was incorrectly labelled as “CrSRTb” and the correct label is “CrSRTB”. These errors have been corrected in both the PDF and HTML versions of the Article.
