抄録

NO_2 fumigation at 8 ppm of spinach plants resulted in nitrite accumulation in the leaves in the dark but not in the light. When spinach plants were fumigated with ^<15>N-labeled NO_2 in the light, amide nitrogen of glutamine, glutamic acid, γ-amino butyric acid and aspartic acid, in this order, were highly labeled with ^<15>N and nitrate was also labeled. These results suggest that NO_2-nitrogen (at least some of it) is converted into nitrite and nitrate, and then actively assimilated into amino acids through the glutamine synthetase/glutamate synthase pathway in spinach leaves.
