For each condition, we calculated the mean values of logFC (−Fe/+Fe) for the two time-points in the light (day), the two time-points in the dark (night), and the four time-points of the experiments (mean). Values are symbolized by the signs + (logFC > 0.2 < 1), ++ (logFC > 1), − (logFC < −0.2 > −1) and – (logFC < −1). Precise values for each time-point are given in Additional file 4: Data sets 1 and Additional file 5: Data sets 2
