Fig. 4From: Identification of key gene networks related to the freezing resistance of apricot kernel pistils by integrating hormone phenotypes and transcriptome profilesEnrichment analysis and co-expression network of hub genes in the brown module associated with IAA. A The KEGG enrichment pathway of hub genes identified in the brown module. B Co-expression network of selected hub genes. Blue nodes represent transcription factors, protein kinases and Ca2+ related proteins; red nodes represent genes in significantly enriched pathways of hub genes. The size of nodes is based on kME. The width of edges is based on weight. C The expression heatmap of hub genes in the co-expression networkBack to article page
