Figure 1: Significantly differentially expressed genes in the roots and leaves of P. simonii treated with either ambient (A) or high (H) temperatures combined with one of two watering regimes (well-watered (W) or drought (D)).

The upper and lower numbers in each fraction indicate the numbers of up- and down-regulated genes, respectively. The overlapping genes under HT (a) were defined as heat responsive genes, and the overlapping genes under drought stress (b) were defined as drought responsive genes. Detailed information about the significantly differentially expressed genes and overlapping genes under each condition compared is presented in Supplementary Tables S2 and S3, respectively.
