The response of diatom central carbon metabolism to nitrogen starvation is different from that of green algae and higher plants [PDF]
, 2011 The availability of nitrogen varies greatly in the ocean and limits primary productivity over large areas. Diatoms, a group of phytoplankton that are responsible for about 20% of global carbon fixation, respond rapidly to influxes of nitrate and are ...

Nitrate Reductase mRNA Regulation in Nicotiana plumbaginifolia Nitrate Reductase-Deficient Mutants [PDF]
The Plant Cell, 1989 Light and substrate regulation of nitrate reductase (NR) expression were compared in wild type and mutant lines of Nicotiana plumbaginifolia. Mutants affected in the NR structural gene (nia) or in the biosynthesis of the NR molybdenum cofactor (cnx) were examined.

On The Regulation of Spinach Nitrate Reductase [PDF]
Plant Physiology, 1990 A coupled assay has been worked out to study spinach (Spinacea oleracea L.) nitrate reductase under low, more physiological concentrations of NADH. In this assay the reduction of nitrate is coupled to the oxidation of malate catalyzed by spinach NAD-malate dehydrogenase.

Cyanate Assimilation by the Alkaliphilic Cyanide-Degrading Bacterium Pseudomonas pseudoalcaligenes CECT5344: Mutational Analysis of the cyn Gene Cluster [PDF]
, 2019 The alkaliphilic bacterium Pseudomonas pseudoalcaligenes CECT5344 can grow with cyanate, cyanide, or cyanide-containing industrial residues as the sole nitrogen source, but the assimilation of cyanide and cyanate takes place through independent pathways.

Nitrogen Oxyanion-dependent Dissociation of a Two-component Complex That Regulates Bacterial Nitrate Assimilation [PDF]
, 2013 Nitrogen is an essential nutrient for growth and is readily available to microbes in many environments in the form of ammonium and nitrate. Both ions are of environmental significance due to sustained use of inorganic fertilizers on agricultural soils ...

Structure and evolution of chlorate reduction composite transposons. [PDF]
, 2013 UnlabelledThe genes for chlorate reduction in six bacterial strains were analyzed in order to gain insight into the metabolism. A newly isolated chlorate-reducing bacterium (Shewanella algae ACDC) and three previously isolated strains (Ideonella ...

Relationships between nitrate uptake and nitrate reductase activity in Cucumis sativus L.
Acta Societatis Botanicorum Poloniae, 2014 Anti-NR IgG fragments obtained after papain digestion of polyclonal antibodies gave the positive immunological reaction with both, a soluble and plasma membrane-bound nitrate reductase.
