Fig. 6From: Exploring gene networks in two sunflower lines with contrasting leaf senescence phenotype using a system biology approachGene co-expression networks analysis (WGCNA). a upregulated TFs and b downregulated TFs at anthesis time, R453 vs. B481–6 with Log2 fold-change > 2 or < − 2. The nodes represent TFs and the edges represent connections between them. The node size and colour are related to the number of connections, large orange nodes represent highly connected hub genes (high degree), small blue nodes represent genes with few connections (low degree). Strong connections are visualized as wider linesBack to article page
