Principal component analyses of the roots and aerial parts of 3 Arabidopsis genotypes. Score scatter plots for roots (A) and aerial parts (B) using all detected peaks are shown. Score and loading plots using 59 commonly detected metabolites for roots (C) and aerial parts (D) are presented. These data include 53 root samples (WT, n = 17; mto1, n = 16; and tt4, n = 20) and 50 samples from aerial parts (WT, n = 17; mto1, n = 13; and tt4, n = 20). Symbols: red squares, wild-type (WT); blue diamonds, mto1; green circles, tt4. Data on the aerial parts were from the work of .
