Figure 6. — NtcA regulatory network and its transcriptional dynamics for the early stages of nitrogen depletion. Target genes are represented by nodes that are colored based on gene expression after 4 h of nitrogen depletion: yellow for upregulated genes, and blue for downregulated genes. Node sizes correspond to the magnitudes of expression changes as a log₂ expression ratio (−N/NH₄). Genes are grouped according to the functional categories obtained from CyanoBase. PPNN: purines, pyrimidines, nucleosides and nucleotides.
