Figure 1

Heat map representing the changes in transcript levels and in the corresponding 23 enzyme activities in rosettes of Arabidopsis. Samples were taken from Col0 WT plants and Col0 pgm growing in a 12 h night and 12 h day cycle, throughout one day and night cycle, and in WT plants transferred to an extended night (XN). Log₂ ratios were calculated for each value, by dividing it by the average of diurnal WT values and applying the logarithm (base 2). Log₂ ratios give the intensity of the blue or red colors, according to the scale from the legend. Relative proportions among isoforms were calculated using the entire dataset and give the intensity of the gray color. These data are taken from [4] and [37]. CHO, carbohydrate.
