Fig.4

Identification of stage-specific DEGs and TFs with crucial roles in breast muscle melanin deposition process. A The expression levels and fold change of stage-specific DEGs at various stages of melanin deposition. The size of circle represents the normalized gene expression level in Silkies and the color of circle represents the fold change between Silkies and Wenchang chickens. B The normalized gene expression of TFs significantly enriched in promoters of stage-specific DEGs, and the top representative motif are shown below TFs. C The networks of stage-specific DEGs regulated by TFs. The colors of edges are the PCC between stage-specific DEGs and TFs (purple for upregulated; yellow for downregulated). Red circles represent enriched TFs, and blue circles represent stage-specific DEGs
