Asr1 methylation status following stress. Leaf genomic DNA from water-stressed plants was subjected to the bisulphite procedure and then cloned (10 idependent clones) and sequenced. Results are displayed as dot plots (Kismeth software) as described in the Methods section. Filled circles, methylated; empty circles, unmethylated. The numbers indicate cytosine residue positions starting from the first analysed cytosine. Residues 32 and 33 are particular cytosine residues that were individually analysed later (Figure 6.).
