Figure 2. Four groups of transcriptional induction upon exposure to mannitol.

• A–D
  Based on a threshold of log₂(FC) > 1, the 20 TFs were categorized into four groups. The first group contains TFs that reached the log₂(FC) threshold 40 min after mannitol treatment (A), the second group reached the threshold after 1 h (B), the third group after 2 h (C), and the fourth group after 4 h (D). The arrow indicates the initial upregulation of every group.

Data information: Data are presented as mean ± SEM. n = 4 independent experiments. FC = fold change. FDR values are available in Table EV1.
