Fig. 3

Average methylation levels across protein-coding genes in CG, CHG and CHH contexts. Gene bodies (highlighted by blue bar) as well as flanking regions 2 kb upstream from transcription start site (TSS) and 2 kb downstream from transcription termination site (TTS) are shown in the plots. Roots and leaves grown on the ISS (RF and LF) are indicated by magenta lines, whereas roots and leaves grown on the ground (RG and LG) are indicated by teal lines
