Metabolic pathway network analysis of differentially expressed genes in response to water deficit treatment. Cytoscape graph depicting genes with an FDR of <0.2 with known links to pathways in plant metabolic networks. Genes and pathway interactions are found in two main clusters, cluster a (a, i), and cluster b (a, ii) as well as numerous small ‘unlinked’ clusters (a, iii and iv). Sub-clusters are also identified within cluster a (b i, ii, iii, iv) and cluster b (c i, ii, iii, iv, v, vi)
