Principal component analysis (PCA) and Partial least squares-discriminate analysis (PLS-DA) score plots for metabolites in wheat leaves and roots under control and drought stress conditions. a) score plot for control leaves (CL; green), drought stress leaves (DSL; blue), control roots (CR; red) and drought stress roots (DSR; black) samples, b) score plot for CR and DSR samples, c) score plot for CL and DSL samples, d) PCA score plot for DSL and DSR samples and e) PCA score plot for CL and CR samples
