Rice module-related co-expression network, and MapMan ontology term enrichment for Modules 34 and 42. (Left panel) Module based gene co-expression network in rice. Different colors of the nodes (modules) indicate different cell wall composition associated with the module eigenvectors. Colors as indicated in Figure 3 (clade color code). (Right panel) Pie charts depicting ontology term enrichment for genes in Modules 34 (upper pie) and 42 (lower pie). Only major Bin terms have been used for pie construction. For complete set, see Additional file 9A and B. Only ontology terms with a significance score above 0.001 are shown.
