Expression profile of differentially expressed genes (DEGs) clustering. a Hierarchical clustering display of the up- and down-regulated genes in the root indicated the gene expression patterns of severe stress were more similar to mild drought stress. Very mild stress and recovery showed a correlation. b Root gene expression profile clustering showed seven groups with normalization values between 2 and -2. Standardized expression levels are shown on y-axis and stress level on x-axis. Each group is represented by the gene expression profiles under different drought levels. Group1: genes up-regulated under SR treatment, but down-regulated under MS treatment, constantly under VMS and SS treatments; Group2: genes up-regulated under VMS and SR treatments, but down-regulated under MS and SS treatments; Group 3: genes up-regulated under VMS treatment, but downregulated under SS treatment, constantly under MS and SR treatments; Group4: genes up-regulated under MS treatment, but down-regulated under VMS and SS treatments, constantly under SR treatment. Group 5: genes up-regulated under SS and SR treatments, but down-regulated under VMS and MS treatments; Group6: genes up-regulated under MS and SS treatments, but down-regulated under VMS and SR treatments. Group 7: genes up-regulated under VMS treatment, but down-regulated under SR treatments, constantly under MS and SS treatments
