Network comparison between maize and Arabidopsis. a A maize module functioning in photosynthesis. Red color indicates the gene has conserved interaction(s) in the Arabidopsis network. The maize genes’ Arabidopsis homologues are shown in parenthesis. b An Arabidopsis sub-network for the homologues of the maize genes in (a). c A maize gene is considered to have conserved interaction(s) in Arabidopsis if its homologues and at least one of its interactors’ homologue also interact within the Arabidopsis network
