Nitrate reductase activity and protein concentration of two populas clones.
Nitrate reductase activity and protein percentage of various tree parts of two Populus clones were determined in relation to nitrate ion activity. Nitrogen was supplied as NH(4)NO(3) in a nutriculture system. Wisconsin-5 had significantly greater nitrate reductase activity than Tristis No. 1. Protein percentages of leaf plastochron index 10 leaves (tenth leaf below first leaf lamina exceeding 2...
متن کاملAnalysis 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 کاملNitrate effects on nitrate reductase activity and nitrite reductase mRNA levels in maize suspension cultures.
Nitrate reductase (NR) activity and nitrite reductase (NiR) mRNA levels were monitored in Black Mexican Sweet maize (Zea mays L.) suspension cultures after the addition of nitrate. Maximal induction occurred with 20 millimolar nitrate and within 2 hours. Both NR and NiR mRNA were transiently induced with levels decreasing after the 2 hours despite the continued presence of nitrate in the medium...
