Principle component analysis (PCA) plot of 21 variables (the same variables used in Fig. 4) in 24 wheat cultivars. All the data are based on the ratio of N deficient to N sufficient treatments. SDW, shoot dry weight; R/S, root to shoot ratio; RL, root length; EC, electrical conductivity; Chl, chlorophyll content; H2O2, hydrogen peroxide content; MDA, malondialdehyde content; Sucrose, soluble sugar content; Starch, starch content; TNC, total non-structural carbohydrates; C/N, carbon to nitrogen ratio; N, leaf total nitrogen content; 16:0, palmitic acid; 16:1, hexadecylenic acid; 16:2, hexadecadienoic acid; 16:3, hexadecatrienoic acid; 18:0, stearic acid; 18:1, oleic acid; 18:2, linoleic acid; 18:3, linolenic acid; DBI, double bond index
