Correlations were calculated from measurements of 40 samples representing 8 lines in 5 replications each. Bolded values: P<0.05. Underlined values: P<0.001. G6PDH: glucose-6-p dehydrogenase, ALD: fructose-biphosphate aldolase, PGK: phosphoglycerate kinase, GAPDH: NADP-dependent glyceraldehyde 3-phosphate dehydrogenase, GLK: glucokinase, PGM: phophoglucomutase, NADP-IDH: NADP-dependent isocitrate dehydrogenase, IDH: NAD-dependent isocitrate dehydrogenase, FUM: fumarase. TCA: tricarboxylic acid cycle.
