Visualization, integration and analysis of plant metabolic networks. (A) Metabolic network representing sugar metabolism in SBGN. A new node for the morphological parameter fresh weight (FW) was added to the network. (B) Integration of metabolic data into the network by visualization of corresponding charts inside the nodes. Metabolite concentrations are mapped to simple chemical glyphs whereas enzyme activity data is mapped to macromolecule glyphs. Bar charts display respective values for all Arabidopsis thaliana accessions of climate class A. (C) 1:n correlation analysis on mapped data for the detection of correlations between the morphological parameter FW and all other metabolic parameters. Correlation coefficients are visualized by color-coded nodes.
