Fig. 2From: Integrative molecular profiling indicates a central role of transitory starch breakdown in establishing a stable C/N homeostasis during cold acclimation in two natural accessions of Arabidopsis thaliana Principal component analysis (PCA) on levels of (a) the primary C/N-metabolome, (b) protein abundance, and (c) phosphopeptide abundance. Accession samples are represented by filled circles (Cvi) and filled diamonds (Rsch). Blue colour indicates non-acclimated samples, black colour indicates acclimated samples. Detailed information about loadings and explained variances of the PCA as well as absolute levels of metabolites, relative levels of proteins and phosphopeptides are provided in the supplementsBack to article page
