Maize domestication gene network. Regulatory relationships among genes contributing to differences in plant and inflorescence architecture between maize and teosinte which are reported in this article or known from the literature. Solid lines and arrows indicate direct regulatory interactions supported by ChIP and gene expression assays or RNA–DNA complementary binding for corngrass1. Dotted lines and arrows indicate interactions based on gene expression assays alone and thus uncharacterized as to whether they are direct or indirect. The gray cone represents shading or a reduction in the ratio of red:far-red light. Red starbursts demark genes that show evidence of selection during domestication.
