Learned regulatory network from an unselected list of 15,000+ genes. The learned network structure starting from a set of nine genes (four clock and five GATA genes of interest), with additional genes added to the network from an unselected set of 15,000+ genes - all the probes on the microarray after filtering out low entropy signals. The number in parentheses next to the gene name denotes the order it was added to the network. The nodes coloured green signify that the genes are localized in the chloroplast. It is also worth noting that the large number of undirected edges indicates that there are many equivalently predictive networks which model the data equally well particularly between these chloroplast localized genes.
