Fig. 3 — DNA methylation level (a) Principle component analysis (PCA) of reduced representation bisulfite sequencing cytosine methylation data. Left diagram: control condition (blue) and -Zn (green). Right diagram: zinc, nitrogen and phosphorus deficiencies, data partially from [22]. The first two PCs are shown. b Overall methylation level (in percent) in all contexts, control: blue; -Zn: green. c Average (across 5 million basepair grids) methylation level in chromosome 1 in all contexts. d Contribution of each context methylation to the total methylation level, control: left; -Zn: right
