Fig. 6From: Time-series transcriptome provides insights into the gene regulation network involved in the volatile terpenoid metabolism during the flower development of lavenderWGCNA of 9246 DEGs at different developmental stages of lavender flower. a Hierarchical cluster tree showing 22 modules of co-expressed genes. Each of the 9246 DEGs is represented by a leaf of the tree and major tree branches constitute 22 modules, labeled with different colors at the lower panel. Note that module ‘Grey’ is for unassigned genes. b Expression heatmap of genes clustered in 21 modules (exclude module ‘Grey’). c The correlations between 56 volatile terpenoids and modules. Each row represents a module and each column represents a terpenoid. The color of each block at the row–column intersection indicates the correlation coefficient: red for high positive correlation and blue for high negative correlation, with a scale shown on the right of the panel. The number of DEGs involved in each module is presented in parentheses in the left panel. Asterisks indicate significant correlations (*P < 0.05, **P < 0.01)Back to article page
