Fig. 6

Heat maps of TF genes between the three comparisons (L2 vs H2, L4 vs H4, and L6 vs H6). Red rectangles represent the up-regulated unigenes, and green rectangles represent the down-regulated unigenes. All information for each gene list can be found in Table S10. L2, L4 and L6 respectively represents the samples from the plants under 19 °C treatment for 2 d, 4 d, and 6 d; H2, H4 and H6 respectively represents the samples from the plants under 23 °C treatment for 2 d, 4 d, and 6 d
