Principle component (PC) analysis-based visualization of transcriptomic data. Projected on the top two PCs (covering 27% and 15% of total variation, respectively), samples are well separated according to environmental condition (a) but not according to genotype (b). The considered environmental conditions are control, drought (D), heat with low relative air humidity (H_LrH), heat with high relative air humidity (H_HrH), drought stress combined with low air humidity heat stress (DH_LrH) and drought stress combined with high air humidity heat stress (DH_HrH). The considered genotypes are Col-0 wild type (WT), pip2;1 pip2;2 double mutant (DM) and pip2;1 pip2;2 pip2;4 triple mutant (TM). PIP2;1 and PIP2;2 are the major aquaporins in leaf tissue
