General Information

EC Number General Information Comment Organism
1.4.1.14 physiological function NADH-GOGAT1 insertion mutants show significant reduction in NADH-GOGAT activity in the grain. The grain weight of neither the NADH-GOGAT1 mutant nor that of the NADH-GOGAT2 mutant is significantly different from that of Nipponbare. The NADH-GOGAT1 mutant does not show a significant difference in grain protein concentration. Loss-of-function of NADH-GOGAT1 leads to an increase in glutelin acidic (14%) and basic subunits (19%). Both the NADH-GOGAT1 and the NADH-GOGAT2 mutant show higher free amino acid concentrations in their grains than does Nipponbare Oryza sativa Japonica Group
1.4.1.14 physiological function the grain weight of neither the NADH-GOGAT1 mutant nor that of the NADH-GOGAT2 mutant is significantly different from that of Nipponbare. A loss of NADH-GOGAT2 function leads to an increase of almost 20% in grain protein concentration. Loss-of-function of NADH-GOGAT2 leads to an increase in concentrations of both glutelins and prolamins. The concentrations of all glutelins, their precursors, and their acidic and basic subunits in the NADH-GOGAT2 mutant increases by 27-40%. Prolamins accumulate in the grains of the NADH-GOGAT2 mutant to higher concentrations. Both the NADH-GOGAT1 and the NADH-GOGAT2 mutant show higher free amino acid concentrations in their grains than does Nipponbare Oryza sativa Japonica Group
