Molecular characterization of nitrate reductase gene and its expression in the marine red alga Gracilaria tenuistipitata (Rhodophyta)
(SPRINGER, 2010)
The enzyme nitrate reductase (NR) responsible for the conversion of nitrate to nitrite is considered to be the rate-limiting step in nitrogen assimilation. The economically important marine macroalga Gracilaria tenuistipitata ...
Nitric oxide inhibits nitrate reductase activity in wheat leaves
(Elsevier Masson, 2011-02)
Nitrate reductase (NR), a committed enzyme in nitrate assimilation, is involved in the generation of nitric oxide (NO) in plants. In wheat leaf segments exposed to sodium nitroprusside (SNP) or S-nitrosoglutathione (GSNO), ...
Nitrate reductase activity in field-grown pueraria lobata (Kudzu) in southeastern Brazil.
(Pesquisa Agropecuaria Brasileira, Brasilia, v.33, n.12, p.1971-75,dez.1998., 2011)
The effect of the sixth sulfur ligand in the catalytic mechanism of periplasmic nitrate reductase
(John Wiley & Sons Inc, 2009-11)
The catalytic mechanism of nitrate reduction by periplasmic nitrate reductases has been investigated using theoretical and computational means. We have found that the nitrate molecule binds to the active site with the Mo ...
Growth, nutritional status and nitrogen metabolism in Vigna unguiculata (L.) Walp is affected by aluminum
(2014-01-01)
Al toxicity is one of the most important abiotic stresses that reduce the growth and development of plants. From a physiological standpoint, Al affects the activity of several important enzymes such as nitrate reductase, ...
Structural and functional characterization of the Colletotrichum lindemuthianum nit1 gene, which encodes a nitrate eductase enzyme
(Genetics and Molecular Research, 2017)
Application methods of Azospirillum brasilense in first- and second-crop corn
(Univ Federal Campina Grande, 2019-11-01)
This study investigated whether inoculation of Azospirillum brasilense in the seeds or sowing furrow could reduce the need for nitrogen fertilizer application in the corn grown in the first and second crop harvest. The ...
Growth and biochemical alterations in coffee due to selenite toxicity
(Kluwer Academic PublDordrechtHolanda, 1998)
Expressed sequence tags related to nitrogen metabolism in maize inoculated with Azospirillum brasilense
(Funpec-editora, 2017-06-14)
The relative quantitative real-time expression of two expressed sequence tags (ESTs) codifying for key enzymes in nitrogen metabolism in maize, nitrate reductase (ZmNR), and glutamine synthetase (ZmGln1-3) was performed ...
