Glutamine Synthetase in Rice: A COMPARATIVE STUDY OF THE ENZYMES FROM ROOTS AND LEAVES.

abstract：:Here, we investigated the physiological role of Arabidopsis (Arabidopsis thaliana) AtNUDX6, the gene encoding ADP-ribose (Rib)/NADH pyrophosphohydrolase, using its overexpressor (Pro35S:AtNUDX6) or disruptant (KO-nudx6). The level of NADH in Pro35S:AtNUDX6 and KO-nudx6 plants was decreased and increased, respectively,...
