Importance of the two dissimilatory (Nar) nitrate reductases in the growth and nitrate reduction of the methylotrophic marine bacterium Methylophaga nitratireducenticrescens JAM1

Frontiers in Microbiology, 2015
Methylophaga nitratireducenticrescens JAM1 is the only reported Methylophaga species capable of growing under anaerobic conditions with nitrate as electron acceptor.

Mesoporous Silica Nanoparticles With Customized Drug Ratio/Loading for Effective Treatment of Gemcitabine‐Resistant Pancreatic Tumors

Advanced NanoBiomed Research, EarlyView.
Redox responsive mesoporous silica nanoparticles (MSNs) were engineered to deliver gemcitabine (Gem) and cisplatin (cisPt) at defined ratios to overcome chemoresistance in pancreatic ductal adenocarcinoma (PDAC). Optimized Gem MSNs and Gem cisPt MSNs enhanced cytotoxicity in murine and human Gem resistant models, with select formulations inducing ...

Differential expression of nitrate reductase in response to potassium and sodium nitrate: realtime PCR analysis

, 2012
Cucurbita pepo L. plants were grown in plastic pots with 2 kg washed sand per pot at three levels of potassium and sodium nitrate supplies to investigate the effects of nitrate supply on nitrate reductase activity and nitrate reductase expression in the ...

Detection of nitrate reductase activity in nitrate reductase deficient mutants of barley (Hordeum vulgare)

, 1983
Nitrate reductase deficient mutants of barley Az12 and Az13 showed 40-50% in vivo enzyme activity as compared with the Steptoe non-mutant under strictly anaerobic conditions of assay.

Regulation and Symbiotic Role of nirK and norC Expression in Rhizobium etli

Molecular Plant-Microbe Interactions, 2011
Rhizobium etli CFN42 is unable to use nitrate for respiration and lacks nitrate reductase activity as well as the nap or nar genes encoding respiratory nitrate reductase.

Nitrate transport and assimilation in Aspergillus nidulans

, 2012
In this study, several aspects of nitrate assimilation and transport have been studied using the filamentous fungus Aspergillus nidulans, which has been shown to be safe laboratory organism as judged by it’s pathogenicity towards insect larvae.

Omeprazole Treatment Enhances Nitrogen Use Efficiency Through Increased Nitrogen Uptake and Assimilation in Corn

Frontiers in Plant Science, 2019
Omeprazole is a selective proton pump inhibitor in humans that inhibits the H+/K+-ATPase of gastric parietal cells. Omeprazole has been recently shown to act as a plant growth regulator and enhancer of salt stress tolerance.

Purification and Characterization of Nitrate Reductase (NAR) from Pseudomonas sp. SH7 Isolate

مجلة مركز بحوث التقنيات الاحيائية, 2010
Sixty five soil samples and fifteen water samples were collected from different places in which previously explosions were occurred in Iraq. Seven isolates showed ability to utilize 0.1mM trinitrotoluene (TNT) and/or 0.2mM glycerol trinitrate (GTN) as a

Nitrate and nitrate reductase in papaw fruit [PDF]

, 1972
Because high nitrate (NOs-) levels in Queensland-grown papaws (Garica papaya L.) cause severe detinning in canned fruit products, some factors affecting the level of nitrate in this fruit have been examined.

A novel mechanism for dissimilatory nitrate reduction to ammonium in Acididesulfobacillus acetoxydans

mSystems
The biological route of nitrate reduction has important implications for the bioavailability of nitrogen within ecosystems. Nitrate reduction via nitrite, either to ammonium (ammonification) or to nitrous oxide or dinitrogen (denitrification), determines
