Glutamate dehydrogenase (GDH) tends to have a lower affinity for ammonium than glutamine synthetase (GS) in higher plants. Consequently, nitrogen is mostly assimilated as ammonium by the GS/glutamate synthase pathway which requires 2-oxoglutarate (2-OG) as carbon skeletons. In contrast, the NADP(H)-dependent GDH in fungi has a higher affinity for ammonium(More)
Heterologous expression of a fungal NADP(H)-GDH gene ( MgGDH ) from Magnaporthe grisea can improve dehydration stress tolerance in rice by preventing toxic accumulation of ammonium. Glutamate dehydrogenase (GDH; EC 1.4.1.2 and EC 1.4.1.4) may act as a stress-responsive enzyme in detoxification of high intracellular ammonia and production of glutamate for(More)
