Fig. 4

GC–MS-based total ion chromatogram of derivatized primary metabolites from Arabidopsis rosette leaves. Intensity of eluted peaks versus retention time (seconds) are shown. Identities of the most abundant metabolites are indicated. More than 90 compounds from this GC-MS data were annotated (Additional file 1: Table S3). These compounds include amino acids and their derivatives, sugars, sugar acids, sugar alcohols, sugar derivatives, organic acids and their derivatives, fatty acids, sinapates, amines and others
