Fig. 4From: Exploring gene networks in two sunflower lines with contrasting leaf senescence phenotype using a system biology approachMetabolism overview using Mapman. Post-anthesis vs. Anthesis in a early senescence line (R453), and b delayed senescence line (B481–6). Genes and metabolites are represented by squares and circles, respectively. Colour intensity corresponds to the expression ratio at logarithmic scale (log2). Red: upregulated, blue: downregulatedBack to article page
