a Principal component analysis (PCA) of the most intense molecular features (n = 12,544, average signal abundance >200,000) in the complete dataset, visualizing the data reduced into the two main orthogonal components explaining the maximal proportion of the variation between samples. Principal component 1 (PC 1) explains 17.6% of the variability between the metabolic profiles of the samples and roughly corresponds with the treatment effect. PC 2 explains 8.84% of the between samples variation and indicates differences between the cereal species. b A simplified phylogenetic classification of the four studied temperate cereals, according to Soreng et al.52.
