Coexpression and regulatory networks of DEGs involved in carotenoid biosynthesis and chlorophyll metabolism. A: Gene coexpression network of the blue module. B: Gene coexpression network of the green module. C: Subnetwork of putative transcription factors (TFs) and structural genes related to carotenoid biosynthesis and chlorophyll degradation from the blue module. D: Subnetwork of putative TFs or other genes from the green module. Green circles denote target genes, and red circles denote TFs. The lines between the two dots indicate their interactions. The colours of lines represent the strength of correlations between the target genes and TFs; the bluer the stronger and the yellower the weaker the interactions between TFs and target genes. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
