Genetic effects and heritabilities of nine CCM enzyme activities.

Values were calculated from a set of 8 diverse maize inbred lines grown and measured in five replications.
aIDH: NAD-dependent isocitrate dehydrogenase, G6PDH: glucose-6-phosphate dehydrogenase, ALD: fructose-biphosphate aldolase, PGM: phosphoglucomutase, FUM: fumarase, NADP-IDH: NADP-dependent isocitrate dehydrogenase, PGK: phosphoglycerate kinase, GLK: glucokinase, GAPDH: NADP-dependent glyceraldehyde 3-phosphate dehydrogenas.e.
bThe taxa effect in a one-way ANOVA.
cBroad-sense heritability, the proportion of the genetic variation from the total phenotypic variation (σ2G/(σ2G+σ2E)).
dNormalized heritability was calculated in the same way as broad-sense heritability but using normalized enzyme activity values that are the difference between each individual standardized activity value of a sample and the mean standardized activity of each sample across the 10 enzymes.
