Gene regulatory network (GRN) for endomesoderm specification in sea urchin embryos. GRN for period from initiation of zygotic regulatory control shortly after fertilization to just before gastrulation (∼6-30 h). The short horizontal lines represent relevant cis-regulatory modules of indicated genes on which the color coded inputs impinge. The sources of these inputs are other genes of the GRN, as indicated by the thin colored lines. Small open and closed circles represent protein-protein interactions that occur off the DNA and are not included explicitly in the GRN, the objective of which is to display the predicted genomic regulatory organization responsible for spatial and temporal expression of the genes it includes. For symbolism, explanations, and access to the BioTapestry software by which the GRN is built and maintained see (http://sugp.caltech.edu/endomes/webstart/bioTapestry.jnlp), where current version of GRN is posted.
