Figure 2: PCA score plot of 1H NMR spectra of Arabidopsis thaliana Col-0 whole above-ground tissue.

Metabolic profiles of 14-day-old diploids (blue circles) and autotetraploids (red circles) are represented. Each dot represents the metabolic profile of a single plant. Each ploidy had a clearly distinct NMR-based metabolic profile as no overlap is observed between diploids and autotetraploids.
