2D principal component analysis (PCA) of 111 compounds (obtained from FAME (F), leaf cutin (C) and LCMS profiling (L) of WT and> tgg1, tgg2 single and tgg1 tgg2 double mutants of Arabidopsis (n = 5), based on log2 ratio amended concentration levels (median) for single metabolites (Supplementary Table S4).
A total of 53.2% of variation is explained by PC1 and PC2. (a) PCA plot showing differences among wild-type and tgg single and double mutants for metabolic profiles. (b) Loading plot of metabolites explaining the observed variation in PCA plot, indicated by coloured lines for the different compound groups following the colour scheme used in Fig. 6.
