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 کاملDetection of genes for membrane-bound nitrate reductase in nitrate-respiring bacteria and in community DNA.
A nested PCR primed by four degenerate oligonucleotides was developed for the specific amplification of sequences from the narG gene encoding the membrane-bound nitrate reductase. This approach was used to amplify fragments of the narG gene from five Pseudomonas species previously shown to be able to express the membrane-bound nitrate reductase and from community DNA extracted from a freshwater...

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 کاملMolybdenum and Nitrate Reductase
Numerous investigators have shown that nitrate nitrogen accumulates in higher plants (l-3) and fungi (2, 4) which are deficient in molybdenum. Other workers have shown that sulfur, zinc, and manganese deficiencies in higher plants may also result in a similar phenomenon (5). The free amino acids present in molybdenum-deficient plants are usually less than those in normal tissues, thus indicatin...
