Fig. 7From: Genome-wide identification and expression profiling analysis of maize AP2/ERF superfamily genes reveal essential roles in abiotic stress toleranceHeat map and topological map of gene expression profile in the module. A Turquoise module (B) blue module (C) brown module (D) yellow module (E) green module (F) red module. In the heat map, blue indicates low expression and red indicates high expression. The black line in the topological graph indicates the interaction between genes, and the thicker the line is, the deeper the relationship is; the ellipse represents genes, and the color represents the score of genesBack to article page
