Transcript levels of genes in metabolic pathways of fatty acid biosynthesis (a), nitrogen metabolism (b), and amino acid metabolism (c) in D5A during N deprivation [5 mM (NH₄)₂SO₄, − N] compared to N replete [35 mM (NH₄)₂SO₄, + N]. The numbers in the shaded rectangles next to blue gene names indicate the log₂-transformed fold changes in time points T1, T2, and T3, from left to right, respectively. Shades of green indicate the respective degree of which the gene is down-regulated and shades of red indicate the respective degree of which the gene is up-regulated. All transcriptional differences are shown as the mean of duplicate log₂-based values
