Schematic Synechocystis sp. metabolisms, with associated heatmaps. Heatmaps represent expression values for a set of significantly (p < 0.05) variable (LFC > 1) genes in the comparison B12 (−N vs +N) on the right, and the corresponding expression values in the comparison 6803 (−N vs +N) on the left. Differentially expressed genes are grouped according to the pathway: A photosynthesis, B carbon fixation, C nitrogen metabolism, D carbon metabolism and E PHB biosynthesis. Red shadows indicate upregulated genes while blue is used for downregulated genes, with the scale bar showing LFCs. * indicates p < 0.05, ** p < 0.01 and *** p < 0.001. PSII, photosystem II; PQ, plastoquinone; Cyt b6f, cytochrome b6f; PSI, photosystem I; Fd, ferredoxin; FNR, Fd-NADP+ oxidoreductase; Cyt bd, cytochrome bd; CCM, carbon concentrating mechanism; CBB cycle, Calvin–Benson–Bassham cycle; PPP, pentose phosphate pathway; FBP, fructose 1,6-bis-phosphate; Ru5P, ribulose 5-phosphate; PHB, poly-hydroxy-butyrate biosynthesis; TCA cycle, tricarboxylic acid cycle; Gln, glutamine; Glu, glutamate; NiR/NaR, nitrite/nitrate reductases; NH4, ammonium; NO3, nitrate
