MetabolomicsNitrate Reductase NarGHJI Modulates Vancomycin Susceptibility by Coordinating Cell Wall Remodeling and Agmatine Metabolism in Staphylococcus aureus
Staphylococcus aureus is a ubiquitous pathogen responsible for a wide range of severe infections. Our previous work established that the nitrate reductase NarGHJI modulates bacterial pathogenicity through regulation of the agr system, yet its role in antibiotic resistance remains poorly understood. ...

TranscriptomicsExpressionprofiling of a glnR-mutant of Mycobacterium tuberculosis during culture on nitrate
Identification of glnR-dependent regulation of nitrate assimilation Keywords: genetic modification Mycobacterium tuberculosis H37Rv wild type and glnR mutant strain were incubated in minimal medium supplemented with 5 mM NO3 for 18 and 48 hours. RNA was extracted at indicated time points and microa...

TranscriptomicsNext generation sequencing for understading the role of nitrate reductase in remodeling intermediate metabolism in Phaeodactylum tricornutum
We have done next generation sequencing of optically thin, exponentialy growing WT Phaeodactylum tricornutum and our ~50% nitrate reductase knock-down cultures. Culture were grown with and without nitrogen source to improve our undestanding of the pathways regulation under conditions that promote li...

TranscriptomicsTranscriptional characterization of maize roots in response to urea and nitrate
Although urea is the most used nitrogen fertilizer worldwide, little is known on the capacity of crop plants to use urea per se as a nitrogen source for development and growth. To date, the molecular and physiological bases of its transport have been investigated only in a limited number of species....

ProteomicsInteractome of the Escherichia coli nitrate reductase respiratory complex, NarGHI, under various metabolic conditions
Cellular respiration is a fundamental process undergone within energy-transducing membranes through the redox activity of multimeric protein assemblies, so-called respiratory complexes. In most cases, electron transport is ensured by lipophilic molecules, quinones, serving as electron shuttles. This...

TranscriptomicsTranscription profiling of Arabdiopsis wild type and G'4-3 seeds grown with different nitrate concentrations to investigate effects on seed dormancy
Freshly harvested Arabidopsis seeds (ecotype Col0 obtained under 10 mM nitrate nutrition, referred to as C10 seeds) are dormant and do not germinate when sown on an agarose-based medium. However, when C10 seeds are sown on 10mM nitrate or when Col0 mother plants are grown on 50 mM nitrate (referred...

ProteomicsNitrate reduction to ammonia by Acididesulfobacillus acetoxydans, an acidophilic sulfate reducing bacterium
Acididesulfobacillus acetoxydans is an acidophilic sulfate reducer that can dissimilatory reduce nitrate to ammonia (DNRA). However, no known nitrite reductase is encoded. This study was performed to investigate how A. acetoxydans reduces nitrate to nitrite and elucidated a novel DNRA mechanism and ...

TranscriptomicsFunctional genomic analysis of a nitrate reductase knockdown relative to wild-type in model-ecosystems (mesocosm)
Current advances in genomics and computational biology have afforded novel insight as to how the phenotype is generated from the genotype – systems biology. We argue that systems biology, when viewed through an ecological lens, provides an unprecedented opportunity to understand how genes cascade th...

TranscriptomicsTreatment of Arabidopsis with low concentration of nitrate
The genomic response to low levels of nitrate was studied in Arabidopsis using the Affymetrix ATH1 chip containing more than 22,500 probe sets. Arabidopsis plants were grown hydroponically in sterile liquid culture on ammonium as the sole source of nitrogen for 10 d, then treated with 250 um nitrate...
