Regulation of nitrate reductase (NR; EC 1.6.6.1) breakdown, measured as loss of maximal activity (MNRA), was studied in leaf segments of 7-day-old oat plants in the light for up to 4 h. In segments floating on 1 mM tungstate, NR lost more than 40% of

The in situ and in vitro regulation of nitrate reductase (NR; EC 1.6.6.1) activity by glucose (Glc) and glucose-6-phosphate (Glc6P) was studied in leaf segments of 7-day-old corn plants. In situ, Glc and Glc-6P not only prevented NR inactivation, but

The effect of substrates on the phosphorylation status of nitrate reductase (NR; EC 1.6.6.1) was studied. The enzyme was obtained from the first leaf of 7-day-old oat (Avena sativa L. cv. Suregrain) plants, grown in the light. When desalted crude ext

Summary The effect of water stress on nitrate reductase (NR) activity was studied in detached oat leaves exposed to various levels of oxygen. Drought inhibited NADH:NR only in the presence of oxygen, the higher the concentration of oxygen in the atmo

It is generally accepted that young leaves have higher nitrate reductase (NR) activity than older ones. To determine the physiological basis of this observation and gain a better understanding of the regulation of NR activity, we investigated NR acti

The nitrate induction of NADH:nitrate reductase mRNA in maize roots, scutella and leaves was investigated in the presence and absence of inhibitors of protein synthesis. In the absence of inhibitors, nitrate treatment caused a fairly rapid (2 to 3 h)

Nitrogen metabolism including nitrate reductase (EC 1.6.6.1), glutamate dehydroge-nase (EC 1.4.1.2) and glutamate-oxalacetate aminotransferase (EC 2.6.1.1) activities were studied during growth of petals taken from carnation flowers (Dianthus caryoph

Nitrate reductase (NR, EC 1.6.6.1) is sensitive to O2 concentration, and therefore it was of interest to study the action of H2O2, a normal substance in plant metabolism, on NR activity in segments of 7-, 14- and 17-day-old leaves of oat (Avena sativ

Detached first leaves of 3-day-old corn seedlings (Zea mays L. W64AxW183E) were incubated with nitrate in air or 100% O(2) in the light. Nitrate accumulation in the leaves was not depressed by O(2). NADH:nitrate reductase activity and enzyme protein,
