Weighted gene co-expression network analysis of wheat genes. a Heatmap of eigengene adjacencies. Blue represents negative correlation and red represents a positive correlation. The colored box on the left side of the heatmap illustrates the corresponding module and gene number. b-d Nightingale rose diagrams show the distribution of DEGs of each module under stripe rust, powdery mildew and drought stresses. The sectors with different colors indicate the distinct expression patterns over time after stress treatment. The larger the radius of a sector, the greater number of DEGs is included. “-”, non-significant; “d”, significant down-regulation; “u”, significant up-regulation. The deep-blue number indicates the percentage of differentially expressed genes in corresponding module. e Ten co-expression subnetworks constructed using several TabHLHs as guide genes. The red notes represent TabHLHs. The numbers in bracket correspond to genes annotated for the top GO term and genes in the module
