Roles of cytosolic NADP-dependent dehydrogenases in high-CO₂-triggered accumulation of SA and related defense compounds. A, Simplified scheme of glycolysis and the tricarboxylic acid cycle showing the reactions catalyzed by NADP-ICDH, NADP-ME2, and np-GAPDH. B, Defense compounds in Col-0 and knockout mutants grown at high CO₂ as in Figure 3. Data are means ± se of nine biological replicates. Asterisks indicate significant differences from Col-0 at P < 0.05. AcCoA, Acetyl-CoA; FW, fresh weight; GAP, glyceraldehyde 3-phosphate; IsoCit, isocitrate; OAA, oxoloacetate; 2-OG, 2-oxoglutarate; PGA, 3-phosphoglycerate.
