Analysis of nitrate reductase mRNA expression and nitrate reductase activity in response to nitrogen supply
Nitrate is one of the major sources of nitrogen for the growth of plants. It is taken up by plant roots and transported to the leaves where it is reduced to nitrite in the. The main objective of this research was to investigate stimulatory effects of sodium nitrate, potassium nitrate, ammonia and urea on the production/generation of the nitrate reductase mRNA in Triticum aestivum plants. The pl...
متن کاملInheritance of Nitrate Reductase Activity
-Since the F1 hybrid (B14 X Oh43) had been shown to have a higher (heterotic) level of nitrate reductase activity than either inbred parent (B14 or Oh43), studies were undertaken to determine the mode of inheritance. Standard methods for determining MNendelian inheritance were used to study segregation for level of nitrate reductase activity of individual plants. The genetic material used was t...

متن کاملViscosity effects on eukaryotic nitrate reductase activity.
Rate-limiting processes of catalysis by eukaryotic molybdenum-containing nitrate reductase (NaR, EC 1.7.1.1-3) were investigated using two viscosogens (glycerol and sucrose) and observing their impact on NAD(P)H:NaR activity of corn leaf NaR and recombinant Arabidopsis and yeast NaR. Holo-NaR has two "hinge" sequences between stably folded regions housing its internal electron carriers: 1) Hing...
متن کاملA nitrate reductase inactivating enzyme from the maize root.
The nitrate reductase in the mature root extract of 3-day maize (Zea mays) seedlings was relatively labile in vitro. Insoluble polyvinylpyrrolidone used in the extraction medium produced only a slight increase in the stability of the enzyme. Mixing the mature root extract with that of the root tip promoted the inactivation of nitrate reductase in the latter. The inactivating factor in the matur...
