From: Natural variation in DNA methylation in ribosomal RNA genes of Arabidopsis thaliana
IGS DNA methylation in 45S rRNA gene repeats among Arabidopsis natural accessions. (A) Distributions of relative CR and IGS DNA methylation in 75 natural accessions. The frequency histograms show the range and distribution of CR and IGS DNA methylation in Arabidopsis natural accessions. (B) A correlation between CR DNA methylation and IGS DNA methylation. Means and standard errors were calculated from at least three independent experiments. The gray line is a linear regression of the data (linear regression coefficient, R = 0.68).
