Figure S2. DNA methylation levels at 23 and 37°C.

(A) PCGs and TEs were aligned at their 5′-end or 3′-end and average cytosine methylation levels in the indicated nucleotide contexts were calculated from 3 kb upstream to 3 kb downstream in WT subjected to a control stress (23°C) or to heat stress (37°C). Upstream and downstream regions were divided in 100 bp bins, whereas annotations were divided in 40 bins of equal length. (B) Average cytosine methylation levels at PCGs or TEs up-regulated or down-regulated in heat-stressed WT plants were calculated and represented as in (A).
