Fig. 4
Transcript co-expression network based on Pearson correlation. The network of transcript co-expression links with correlation coefficients higher than 0.6 or lower than −0.6 as visualized in Cytoscape [148]. A circular layout is used for 19 clusters that contain at least 15 nodes. The remaining transcripts are displayed in the middle with a prefuse force directed layout. Node colors and shapes represent the associations of transcripts with the traits (in the figure legend, _P stands for positive and _N for negative correlation with the trait concerned), whereby similarly colored circles and triangles depict opposite associations with the same traits. The strength of the correlations between transcripts is reflected in the hue of the edges
