Figure 7
Correlation of methylation status with gene expression and genome triplication in B. oleracea . (a) Expression levels (log(FPKM)) plotted against mCG gene body methylation levels. (b) Box plot representation of different levels of mCG gene body methylation in syntenic genes (along x-axis) with normalized gene expression levels plotted on the y-axis. (c) Box plot representation of different levels of mCG observed across the three sub-genomes. (d) Correlation of gene expression (FPKM) and methylation levels among the fully retained orthologues of the three genomes. Below the diagonal, positive and negative pair-wise correlations are indicated in blue and red, respectively. Darker coloring indicates a greater magnitude for the correlation. Above the diagonal, the color and extent of the filled area of each of the pie-charts represents the strength of each pair-wise correlation. Positive and negative correlations are indicated by the pie being filled in a clockwise or anticlockwise direction, respectively.
