The inferred network using the CG list was used as a scaffold and extended to include genes from the entire mouse genome by expression profile similarity. Representative annotations using the Gene Ontology database are shown by node color. All annotations are relevant to cardiogenesis with some more specific than others. Edge color and thickness are as in Figure 3. Directional arrows are omitted for clarity. The gene interactions shown are the edges with fidelity scores greater than 2.5. GO term acronyms: MCO, multicellular organismal development; HD, heart development; ASM, anatomical structure morphogenesis; TD, tissue development; NRGE, negative regulation of gene expression; SMTD, striated muscle tissue development; CD, cell differentiation; ESO, extracellular structure organization; SMMP, small molecule metabolic process; OD, organ development; SD, system development; CDP, cellular developmental process; MTD, muscle tissue development; CSD, cardiovascular system development; O, other. White nodes have no annotation ascribed. See also Tables S2 and S3.
