WGCNA of genes in the red- and green-stem cuttings that responded to NAA treatment. a Hierarchical cluster tree showing co-expression modules. Each leaf of the tree represents one gene. The major tree branches constitute 22 modules labelled by different colours. b Module–sample association. Each row corresponds to a module, and each column corresponds to a specific sample. The colour of each cell at the row-column intersection represents the correlation coefficient between the module and the sample. A high degree of correlation between a specific module and the sample is indicated by an underlined module name
