Changes in H3K4 methylation for genes with changes in mRNA levels. Genes that were up- or down-regulated by dehydration stress were grouped into up- or down-regulated quintiles according to their change in transcript levels. The genes showing the largest increase or largest decrease in transcript levels were placed into the 5th or -5th quintiles, respectively. The type of H3K4 methylation is represented by the color key in the upper left corner of the chart. The change in the amount of H3K4 methylation for each type of H3K4 methylation is represented on the y-axis (Change in coverage). For example, a median value (black cross bar) showing no change in H3K4 methylation would be at y-coordinate 0 and a median value showing an increase of 15 in coverage would be placed at y-coordinate + 15. One standard deviation in H3K4 methylation coverage is shown on each side of the median value.
