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 کاملNitrate reductase for nitrate analysis in water
Nitrate analysis in water is one of the most frequently applied methods in environmental chemistry. Current methods for nitrate are generally based on toxic substances. Here, we show that a viable alternative method is to use the enzyme nitrate reductase. The key to applying this Green Chemistry solution for nitrate analysis is plentiful, inexpensive, analytical grade enzyme. We demonstrate tha...
متن کاملBradyrhizobium japonicum cytochrome c550 is required for nitrate respiration but not for symbiotic nitrogen fixation.
Bradyrhizobium japonicum possesses three soluble c-type cytochromes, c550, c552, and c555. The genes for cytochromes c552 (cycB) and c555 (cycC) were characterized previously. Here we report the cloning, sequencing, and mutational analysis of the cytochrome c550 gene (cycA). A B. japonicum mutant with an insertion in cycA failed to synthesize a 12-kDa c-type cytochrome. This protein was detecta...
متن کاملA Toggle Switch in Plant Nitrate Uptake
In plants, the uptake of nitrate from the soil is a critical process controlled by complex regulatory networks that target nitrate transporters in the roots. In this issue, Ho et al. (2009) show that phosphorylation of the CHL1 nitrate transporter allows the plant root to sense and respond to different nitrate concentrations in the soil.
