Fig. 5From: Identification of key genes and pathways associated with feed efficiency of native chickens based on transcriptome data via bioinformatics analysisThe three protein-protein interaction (PPI) hub network modules. The three significant modules, including (a) module 1 (MCODE score = 22.33), b module 2 (MCODE score = 11), and c module 3 (MCODE score = 5.67), were constructed from PPI network of DEGs using MCODE. The red node represents the up-regulated gene, while the green node represents the down-regulated gene. The seed node of each module was shaped as diamond and highlight the blue gene symbol. Node size indicated the fold change of each geneBack to article page
