WGCNA of drought-associated genes in G. furcata. a: Clustering dendrogram and modules for 27805 uni-genes. Each gene is represented by a leaf in the tree, the y axis represents network distance, as determined by topological overlap (TO), different colors shows module membership after being merged. b: Module-trait relationships. Colors on the left represent twenty modules and the numbers of uni-genes were written in each module. A heat-map shows the module eigen-gene (ME) correlations to traits (eight samples for experiment). Numbers in the Coral2 analysis reported the correlation coefficients for the ME-trait relationship. c: Eigengene expression profile for Coral2 module. The bar-plot reported eigengene expression at each sampling point. For the heat-map, rows corresponded to genes, columns to samples, the green color represented under-expressed, the red denoted over-expressed. d: Top ten statistics of KEGG pathway enrichment. The names of those enriched pathways with P< 0.05 were marked in red
