Comparative analysis of transcriptome profiles of wheat seedling leaves under DS, HS and HD. (a) Principal component analysis (PCA) of mRNA populations from control, DS-1 h, DS-6 h, HS-1 h, HS-6 h, HD-1 h and HD-6 h, each sample contained two replicates. Principal components (PCs) 1, 2 and 3 account for 79 %, 10 % and 5 % of the variance, respectively. PCA plot shows two distinct groups of mRNA populations. Group I: CK (green), DS-1 h (yellow) and DS-6 h (brown); Group II: HS-1 h (light red), HS-6 h (dark red), HD-1 h (light blue) and HD-6 h (dark blue). (b) Venn diagrams showing overlap of up- or down-regulated genes in response to the three assayed abiotic stresses at 1 h and 6 h: drought (yellow), heat (red) and combined stress (blue)
