Detection of co-expression network in duck breast muscle. a Hierarchical cluster tree showing co-expression modules identified by WGCNA analysis. Each leaf in the tree is one gene. The major tree branches constitute nine modules labeled by different colors. b Module-tissue association. Each row corresponds to a module. Each column corresponds to a specific fatty acid composition trait. The color of each cell at the row-column intersection indicates the correlation coefficient between the module and the trait. A high degree of correlation between a specific module and the trait is indicated by dark red or dark green. c and d The relationships between the hub genes and lipid metabolism genes in MEblue and MEbrown. The top 150 connections sorted by correlation coefficients among transcripts are shown for each module
