Fig. 4From: Phenotypic divergence between broiler and layer chicken lines is regulated at the molecular level during developmentMitotic cell cycle regulatory network generated from broilers’ upregulated DEGs. A gradient of red was used to indicate upregulated DEGs; darker red indicates higher expression levels. Transcription factors are represented as bold octagons. Arrows indicate the interaction between the regulator and the target gene. White geometric shapes denote genes that are not DEGsBack to article page
