These genes showed an early response under drought treatment in flowers (98 genes, in the a, b, and e groups of Supplemental Figure 5C, are significantly induced at T3 compared with C0 or C3 with at least twofold difference and q-values < 0.01, but not in the group of genes induced at C3 compared with C0; the latter genes likely reflect changes in inflorescence development independent of drought). The fold changes (T3/C0) are calculated from the average expression values of DT samples (T3) to those of the WW control (C0).
