Figure 2

Number of differently expressed genes (DEGs). Diagram of the number of genes modulated between the growth stages, where a different expression was defined as a symmetrical fold change of more than 1.5, a minimal intensity of 7 and a p-value < 0.05. Red represents upregulated genes while green represents downregulated ones. The arrows at the top of the figure illustrate the genes that are regulated in the same way during all the transitions; the ones in the middle represent the genes that are upregulated (red part of the arrow) or down regulated (green part) only during one specific transition; the arrows at the bottom represent the genes that undergo a dramatic shift in their regulation (from downregulation to upregulation, or vice versa). The numbers accompanying the arrows show the number of genes in each category.
