Validation of RNA-Seq data by qPCR. a Relative expression of 12 DEGs. b Significantly positive correlation of 12 DEGs between RNA-Seq and qPCR data (correlation coefficient of 0.781). The fold change represents the change in expression of each gene under drought stress (Si: 10% PEG + 0.6 mmol/L Na2SiO3) relative to the respective control (Control: 10% PEG)
